ABSTRACT

ABSTRACT Purpose: This study aimed to investigate the effect of using a viscoelastic substance in Descemet's membrane rupture in "double bubble" deep anterior lamellar keratoplasty. Methods: The medical records and videos of surgeries of 40 patients who underwent surgery between January 2014 and July 2015 were retrospectively evaluated. The patients were divided into two groups: 20 patients whose perforation of the posterior stromal wall was performed without administration of any viscoelastic substance (group 1) and 20 patients whose perforation of the posterior stromal wall was performed with administration of viscoelastic substance onto the posterior stroma (group 2). The Descemet's membrane perforation rate was compared between groups. Results: Perforation of the Descemet's membrane was observed in 12 (60.0%) patients in group 1 and only three (15.0%) patients in group 2. This difference was statistically significant (p=0.003). Only one (5%) patient in group 2 had macroperforation during the procedure, and the surgery was converted to penetrating keratoplasty. Eleven (55.0%) patients in group 1 had macroperforation of Descemet's membrane, and surgeries were converted to penetrating keratoplasty. This difference between the groups was statistically significant (p=0.001). Conclusions: Administering a viscoelastic substance onto the posterior stromal side just before puncture is an effective method to decrease the risk of Descemet's membrane perforation in deep anterior lamellar keratoplasty.(AU)


RESUMO Objetivo: Investigar o efeito do uso de uma substância viscoelástica na ruptura da membrana de Descemet em casos de ceratoplastia lamelar anterior profunda em "bolha dupla". Métodos: Foram avaliados retrospectivamente prontuários e vídeos de cirurgias de 40 pacientes operados entre janeiro de 2014 e julho de 2015. Os pacientes foram divididos em dois grupos: 20 pacientes nos quais a parede posterior do estroma foi puncionada sem a colocação de nenhuma substância viscoelástica (grupo 1) e 20 pacientes nos quais uma substância viscoelástica foi aplicada sobre o estroma posterior ao ser puncionada a parede posterior do estroma (grupo 2). A taxa de perfuração da membrana de Descemet foi comparada entre os grupos. Resultados: Observou-se perfuração da membrana de Descemet em 12 casos (60,0%) no grupo 1 e em apenas 3 casos (15,0%) no grupo 2. Essa diferença foi estatisticamente significativa (p=0,003). Apenas um caso (5%) no grupo 2 teve macroperfuração durante o procedimento, sendo a cirurgia então convertida em uma ceratoplastia penetrante. Onze casos (55,0%) no grupo 1 tiveram macroperfuração da membrana de Descemet e essas cirurgias foram convertidas em ceratoplastias penetrantes. Essa diferença entre os grupos foi estatisticamente significativa (p=0,001). Conclusões: A aplicação de substância viscoelástica sobre o lado posterior do estroma logo antes da punção é um método eficaz para diminuir o risco de perfuração da membrana de Descemet na ceratoplastia lamelar anterior profunda.(AU)

ABSTRACT

RESUMO Relato de caso não descrito na literatura oftalmológica nacional de múltiplas camadas da membrana de Descemet. Mulher de 59 anos, pseudofácica, com diagnóstico de ceratopatia bolhosa, foi submetida à ceratoplastia penetrante em olho direito, sendo encontrado achado incomum de multiplicidade de camadas da membrana de Descemet, variáveis em forma e espessura, além de corpos ovoides com coloração de metamina de prata de Gocott-Gomori (GMS) negativa. Como a membrana de Descemet tem no seu desenvolvimento um período fetal e outro pós-natal que frequentemente é bem identificável nos cortes histológicos em adultos. No caso apresentado, em que outras camadas estão presentes, há evidência de corpos esféricos que poderiam significar que a potencialidade de produzir outras camadas pode permanecer na fase adulta mais tardia.


ABSTRACT To relate a case not described previously in the national multilateral ophthalmological literature of Descemet's membrane. A 59-year-old pseudophakic woman diagnosed with bullous keratopathy underwent penetrating keratoplasty with an unusual finding of multiple layers of Descemet's membrane, which were variable in shape and thickness. In addition, ovoid bodies with negative Gocott-Gomori (GMS) color were present. Discussion and Conclusion: As Descemet's membrane has a fetal and a postnatal period in its development, it is frequently and well identifiable in histological sections in adults. In the case presented, in which other layers are present, there is evidence of spherical bodies that could mean that the potential to produce other layers may remain into later adulthood.

ABSTRACT

ABSTRACT Description of a patient with Fuchs endothelial dystrophy submitted to a corneal transplant, performed by Descemet membrane endothelial keratoplasty, which evolved with sudden, paroxysmal pain in the frontotemporal region, postoperatively. Due to the ophthalmologic picture of the patient, the attending physician believed in possible rejection of the graft, neglecting the complaint of pain. Even after a successful second transplant, performed due to primary failure, disabling pain persisted and the physician did not manage it. After years of investigation, consulting with several specialists, it was concluded the patient presented trigeminal neuralgia that had not been treated since the surgical procedure. In addition, it led to several psychosocial consequences. Therefore, it is essential to be aware trigeminal neuralgia is a possible outcome of corneal transplantation, and its symptoms should not be neglected by the attending physician, thus contributing to better management for transplanted patients.


RESUMO Descrição do relato de caso de uma paciente com distrofia endotelial de Fuchs submetida a transplante de córnea, realizado pela técnica DMEK, que evoluiu com quadro de dor súbita, paroxística, em região frontotemporal, no pós-operatório. Devido ao quadro oftalmológico da paciente, o médico assistente acreditava em possível rejeição do enxerto, negligenciando a dor. Mesmo após sucesso do segundo transplante, realizado devido à falência primária, as dores incapacitantes persistiam, e nenhuma conduta, por parte do médico, foi realizada. Após anos de investigação, mediante consultas com diversos especialistas, concluiu-se que a paciente apresentava um quadro de neuralgia do nervo trigêmeo que não tinha sido tratada desde a realização do procedimento cirúrgico. Além disso, apresentava uma série de consequências psicossociais. Portanto, torna-se imprescindível entender que a neuralgia do nervo trigêmeo é um possível desfecho do transplante de córnea, e seus sintomas não devem ser negligenciados por parte do médico assistente, contribuindo para melhores condutas para os pacientes transplantados.

ABSTRACT

ABSTRACT This article reports a combined technique of sutureless intrascleral fixated intraocular lens implantation and Descemet membrane endothelial keratoplasty in a patient with anterior pseudophakic bullous keratopathy. Two scleral tunnels were created, corneal incisions were made, and a foldable intraocular lens was cut and removed from the anterior chamber. After performing anterior vitrectomy, a 3-piece foldable intraocular lens was implanted into the anterior chamber. One of the intraocular lens haptics was grasped with a forceps and pulled out from the scleral tunnel. Then, the end of the haptic was cauterized. Similar maneuvers were applied for the other haptic. Next, an 8-mm-diameter donor tissue was prepared, and the recipient endothelial tissue was peeled and removed from the center of the recipient cornea. The prepared donor tissue was injected into the anterior chamber. After proper opening and placement of the donor tissue, an air bubble was injected below the tissue. There were no postoperative complications during the 1-month follow-up.


RESUMO Relato de uma técnica que combina o implante de uma lente intraocular com fixação intraescleral sem sutura e uma ceratoplastia endotelial da membrana de Descemet em paciente com ceratopatia bolhosa pseudofácica anterior. Foram criados dois túneis esclerais. Foram feitas incisões na córnea e a lente intraocular dobrável foi cortada e removida da câmara anterior. Foi então efetuada uma vitrectomia anterior e uma lente intraocular dobrável de 3 peças foi implantada na câmara anterior. Um dos hápticos da lente intraocular foi pinçado com um fórceps e puxado para fora do túnel escleral. A extremidade do háptico foi cauterizada. Manobras semelhantes foram feitas no outro háptico. Foi preparado um tecido de doador com 8 mm de diâmetro e o tecido endotelial da área receptora foi removido do centro da córnea. O tecido preparado do doador foi injetado na câmara anterior. Após abertura e posicionamento adequados do tecido do doador, foi injetada uma bolha de ar abaixo do tecido. Não foi observada nenhuma complicação pós-operatória durante um mês de acompanhamento.

ABSTRACT

ABSTRACT Purpose: The length of Descemet's membrane and donor graft sizes in deep anterior lamellar keratoplasty do not match in very steep corneas, which can lead to Descemet's membrane folds. The aim of this study is to establish a theoretical model for graft size calculations for deep anterior lamellar keratoplasty and evaluate its efficacy for preventing Descemet's membrane folds. Methods: We calculated the arc diameter of the recipient bed by using the cosine formula and developed a table to aid surgeons in donor punch size selection. To test the usefulness of this formula, we evaluated the development of Descemet's membrane folds in keratoconus patients with very steep corneas (K >60 D). In group 1, deep anterior lamellar keratoplasty surgeries were performed using graft sizes that were determined based on our model (n=31). In group 2, graft sizes were determined based on the empirical judgment of the surgeon without any formal calculation (n=30). Results: Our theoretical calculations demonstrated that the diameter of donor punch sizes needed to prevent Descemet's membrane fold increases when the cornea is steeper, or the trephine size is larger. We tested the efficacy of this model on the clinical outcome of deep anterior lamellar keratoplasty. The mean age (28.9 ± 10.1 years vs. 32.8 ± 8.3 years, p=0.11) and preoperative K1 (59.2 ± 9.3 D vs. 58.1 ± 9.4 D, p=0.67), K2 (66.2 ± 6.0 D vs. 65.7 ± 7.4 D, p=0.81), and Km values (62.1 ± 7.7 D vs. 61.8 ± 8.1 D, p=0.88) were similar between the two groups. Three patients developed Descemet's membrane folds in group 2, and none of the patients developed Descemet's membrane folds in group 1. These results supported our theo retical calculations. Conclusion: Adjustment of donor graft size based on the calculated arc diameter of the recipient bed reduced the development of Descemet's membrane folds after deep anterior lamellar keratoplasty in steep corneas.


RESUMO Objetivo: O comprimento da membrana de Descemet e o tamanho do enxerto doador na ceratoplastia lamelar anterior profunda não coincidem em córneas muito íngremes, o que pode levar às dobras da membrana de Descemet. O objetivo deste estudo é estabelecer um modelo teórico para cálculo do tamanho do enxerto para ceratoplastia lamelar anterior profunda e avaliar a sua eficácia na prevenção de dobras da membrana de Descemet. Métodos: Calculamos o diâmetro do arco do leito receptor usando a fórmula do cosseno e desenvolvemos uma tabela para auxiliar os cirurgiões na seleção do tamanho da punção no doador. Para testar a utilidade dessa fórmula, avaliamos o desenvolvimento das dobras da membrana de Descemet em pacientes com ceratocone com córneas muito íngremes (K>60D). No grupo 1, foram realizadas cirurgias de ceratoplastia lamelar anterior profunda, utilizando tamanhos de enxerto que foram determinados com base em nosso modelo (n=31). No grupo 2, os tamanhos dos enxertos foram determinados com base no julgamento empírico do cirurgião sem qualquer cálculo formal (n=30). Resultados: Nossos cálculos teóricos demonstraram que o diâmetro dos tamanhos da punção do doador necessários para evitar as dobras na membrana de Descemet aumenta quando a córnea é mais íngreme ou o tamanho da trefina é maior. Testamos a eficácia deste modelo no resultado clínico da ceratoplastia lamelar anterior profunda. A média de idade (28,9 ± 10,1 anos vs. 32,8 ± 8,3 anos, p=0,11) e K1 pré-operatório (59,2 ± 9,3 D vs. 58,1 ± 9,4 D, p=0,67), K2 (66,2 ± 6,0 D vs. 65,7 ± 7,4) D, p=0,81) e Km (62,1 ± 7,7 D vs. 61,8 ± 8,1 D, p=0,88) foram semelhantes entre os dois grupos. Três pacientes desenvolve ram dobras na membrana de Descemet no grupo 2, e nenhum dos pacientes desenvolveu dobras na membrana de Descemet no grupo 1. Estes resultados apoiam nossos cálculos teóricos. Conclusão: O ajuste do tamanho do enxerto doador com base no diâmetro do arco calculado do leito receptor reduziu o desenvolvimento das dobras na membrana de Descemet após ceratoplastia lamelar anterior profunda em córneas íngremes.

ABSTRACT

ABSTRACT Here, we describe the result of a Descemet's membrane endothelial keratoplasty for acute corneal hydrops in a 45-year-old female with keratoconus, who presented with severe visual loss in her OS. The patient's best-corrected visual acuity was 20/80 in the right eye and hand motion in the OS. Slit-lamp examination revealed an extensive tear of the Descemet's membrane and stromal corneal edema in the OS. We opted for Descemet membrane endothelial keratoplasty. Twelve months postoperatively, the patient had a best-corrected visual acuity of 20/50 in the OS.


RESUMO Trata-se de uma paciente do sexo feminino, de 45 anos, portadora de ceratocone, submetida a uma ceratoplastia endotelial com membrana Descemet após apresentar um quadro de perda de visão severa devido a uma hidrópsia corneana aguda no olho esquerdo. Inicialmente, a acuidade visual corrigida da paciente era de 20/80 no olho direito e de movimento de mãos no olho esquerdo. Após exame de biomicroscopia que detectou uma extensa rotura da membrana de Descemet e edema estromal, optamos por tratar esse caso com o ceratoplastia endotelial com membrana Descemet. Doze meses após o procedimento cirúrgico, percebeu-se uma melhora do edema corneano, não havia sinais de rejeição do botão óptico e a acuidade visual corrigida da paciente era de 20/50 no olho afetado.

ABSTRACT

PURPOSE: To report a patient with a pseudophakic bullous keratopathy (PBK) who underwent Descemet's membrane stripping endothelial keratoplasty (DSEK) with manual preparation of the donor corneal graft.CASE SUMMARY: A 61-year-old female presented with visual disturbance in her right eye. Five months prior, she was treated with phacoemulsification and intraocular lens exchange surgery of the right eye, and a very severe corneal edema was revealed by slit-lamp examination. We diagnosed PBK and planned DSEK with manual preparation of a donor corneal graft because of the non-availability of a microkeratome or a femtosecond laser. After making the corneal graft using an artificial anterior chamber, crescent knife and cornea dissector, the keratoplasty proceeded using the graft. Three months after surgery, her graft was well-maintained on the right eye. The patient's visual acuity was 0.3, and the corneal endothelial cell count was 1,844/mm².CONCLUSIONS: Manual preparation of the donor corneal graft for DSEK is suitable as a second choice treatment method when the availability of surgical devices is limited.

ABSTRACT

PURPOSE: We report a case of herpes simplex keratitis after Descemet membrane endothelial keratoplasty (DMEK). CASE SUMMARY: A 67-year-old male underwent DMEK in his left eye due to pseudophakic bullous keratopathy. One week after DMEK, re-bubbling was performed due to partial detachment of Descemet's membrane at the corneal periphery. After re-bubbling, the cornea remained clear and the patient's visual acuity gradually improved. Two months after DMEK, the patient presented with mild discomfort and decreased visual acuity. The cornea showed an irregular, narrow dendrite with an epithelial defect and surrounding opacity. After confirming that Descemet's membrane was attached, the patient was started on oral valacyclovir for suspected herpes keratitis. Herpes simplex virus type 1 was eventually identified by polymerase chain reaction. The corneal lesion resolved after three weeks of antiviral treatment. CONCLUSIONS: Similar to penetrating keratoplasty, DMEK can trigger outbreaks of herpes simplex keratitis. Herpes simplex keratitis should remain on the clinician's differential diagnosis for patients who present with a corneal epithelial irregularity and decreased visual acuity following DMEK.

ABSTRACT

PURPOSE: To report a case of corneal edema caused by an iatrogenic lidocaine injection into the corneal stroma created while performing a local anesthetic (lidocaine) injection into the eyelid for a blepharoplasty procedure. CASE SUMMARY: A 15-year-old female visited our clinic after the onset of severe pain and decreased visual acuity while receiving a local anesthetic injection in the upper blepharon for a blepharoplasty procedure. At the first clinical visit, visual acuity was hand motion and an accurate anterior chamber examination was difficult because of corneal edema. The Seidel test was negative. On corneal optical coherence tomography, the corneal thickness was 1,580 µm without any sign of Descemet's membrane detachment. We prescribed 5% NaCl four times a day and prednisolone acetate eight times a day. On the next day after injury, the corneal edema was significantly improved (central corneal thickness: 660 µm), and Descemet's membrane detachment was still not observed. One week after injury, the naïve visual acuity was 20/20, the central corneal thickness was 560 µm, and the endothelial cell count was 3,260 cells/cm². Three weeks after injury, the corneal edema was fully resolved and only slight temporal corneal haziness remained. After 2 months, the cornea was clear without any subjective discomfort. CONCLUSIONS: Corneal edema without Descemet's membrane detachment can be resolved spontaneously without aggressive treatment such as gas or air injection. However, endothelial cell count and corneal opacity need to be monitored on follow up exam. This clinical experience suggests that severe corneal edema in anterior stromal layer could be spontaneously resolved without severe complication.

Resultados: As rupturas encontradas foram classificadas em total ou comum, parcial, fratura e bisel. Os afinamentos foram divididos em generalizado, localizado e extensivo. Conclusão: Apresentamos várias nuances das rupturas e dos afinamentos da membrana de Descemet no exame histopatológico. Os achados sugerem, considerando apenas aspectos mecânicos, uma possível relação entre afinamento e ruptura como causa e efeito.


Abstract Objective: To describe the different types of ruptures and thinning of Descemet's membrane found in the histopathological examination, questioning a possible relationship between them. Methods: Observational, transversal, retrospective and descriptive study of corneal buttons from penetrating keratoplasty during the randomly chosen period of four years: 2006, 2010, 2014 and 2015. The staining was performed with hematoxylin-eosin (HE). After preparation, the authors examined the tissues with an optical microscope. We selected only the cases of rupture or thinning of Descemet's membrane in histopathological examination and classified the different types of these findings. Results: The ruptures found were classified as total or common, partial, fracture and bevel. The thinnings were divided into generalized, localized and extensive. Conclusion: We presented several nuances of Descemet's membrane ruptures and thinning in histopathological examination. Considering only mechanical aspects, the findings suggest a possible relationship between thinning and rupture as cause and effect.

ABSTRACT

ABSTRACT Purpose: We report a simplified Descemet's membrane endothelial keratoplasty (DMEK) technique that involves safe and effective preparation and introduction, correct orientation, and easy unfolding of the donor graft inside the recipient anterior chamber. Methods: In this retrospective study, we assessed the surgical outcomes of 26 eyes of 23 consecutive patients (mean age, 61.2 ± 11.4 yr; range, 39-82 yr) with Fuchs endothelial corneal dystrophy (n=19) or bullous keratopathy (n=7) who underwent the Samba technique, a simplified DMEK method, at the Sorocaba Ophthalmology Hospital, Sorocaba Eye Bank, Sorocaba, Brazil, between August 2011 and July 2012. Results: Of the 26 operated eyes, only two (7.7%) experienced partial graft detachment requiring rebubbling, and in those eyes, the graft was reattached successfully with one air bubble. There were no cases of primary graft failure, tissue loss, or pupillary block. All patients with good visual potential achieved a best-corrected visual acuity of 20/30 or better at 6 months, and 82.6% achieved a best-corrected visual acuity of 20/30 or better 1 month postoperatively. Conclusion: In this retrospective study, the Samba technique, a simplified DMEK procedure, was safe and effective, with an acceptably low rebubbling rate and no incidence of primary graft failure or pupillary block. Moreover, rapid and nearly complete visual recovery was achieved. This simplified DMEK technique can be adopted by corneal surgeons worldwide as a primary treatment for endothelial dysfunction with a less steep learning curve and low rate of postoperative complications.


RESUMO Objetivo: Relatar uma técnica simplificada de ceratoplastia endotelial da membrana de Descemet (DMEK) que envolve a preparação e a introdução seguras e eficazes, a orientação correta e o fácil desdobramento do enxerto doador dentro da câmara anterior receptora. Métodos: Neste estudo retrospectivo, foram revisados e avaliados os resultados cirúrgicos de 26 olhos de 23 pacientes consecutivos (idade média: 61,2 ± 11,4 anos, intervalo: 39 a 82 anos) com distrofia corneana endotelial de Fuchs (n=19) ou ceratopatia bolhosa (N=7) submetidos à técnica "Samba", método de DMEK simplificado, no Hospital Oftalmológico de Sorocaba, Banco de Olhos de Sorocaba, Sorocaba, Brasil, entre agosto de 2011 e julho de 2012. Resultados: Dos 26 olhos operados, apenas 2 olhos (7,7%) apresentaram descolamento parcial do enxerto que necessitou de nova injeção de ar na câmara anterior "re-bubble", e nesses olhos o enxerto foi posicionado com sucesso com o procedimento de "re-bubble". Nenhum dos 26 olhos apresentaram falência primária do enxerto ou perda de tecido, ou bloqueio pupilar. Todos os pacientes com bom potencial visual obtiveram a acuidade visual melhor corrigida de 20/30 ou melhor e 82,6% tinham acuidade visual melhor corrigida de 20/30 ou melhor com 1 mês de cirurgia. Conclusão: Neste estudo retrospectivo, a técnica de Samba, um procedimento de DMEK simplificado, mostrou-se segura e eficaz, com uma taxa de "re-bubble" aceitavelmente baixa e nenhuma incidência de falência primária ou complicação com bloqueio pupilar. Além disso, a recuperação visual rápida e completa foi rapidamente alcançada. Esta técnica DMEK simplificada pode ser adotada por cirurgiões de córnea em todo o mundo como um tratamento primário para disfunção endotelial com uma curva de aprendizado rápida e baixa taxa de complicações pós-operatórias.

ABSTRACT

ABSTRACT Purpose: To evaluate microstructural differences between corneas with and without Kayser-Fleischer rings in age-matched subjects with Wilson's disease with neurological symptoms, using confocal laser scanning microscopy. Methods: The study included 12 subjects with Wilson's disease with neurological symptoms. Twelve corneas presented clinically with classic Kayser-Fleischer rings, visible on slit lamp examination; the other 12 served as controls. The subjects underwent a comprehensive clinical examination. Microstructural analysis using confocal laser scanning microscopy evaluated increased corneal thickness, decreased number of cells, increased debris or specific deposits, and unusual microstructures. Results: Clinically, the subjects with Kayser-Fleischer rings had similar corneal findings and normal intraocular pressure; two had typical sunflower cataracts and decreased visual acuity. The control eyes all presented normal visual acuity, intraocular pressure, and corneal appearance. The microstructural analysis demonstrated similar findings in all the affected corneas. Compared with the control corneas, there were fewer keratocytes in the anterior stroma (17.380 vs. 22.380/mm3). Round, "hollow" dark areas were observed between the keratocytes; these were universal and similar in appearance in all affected corneas and all cornea layers. In the peripheral posterior stroma, there were dust-like, bright, granular deposits that tended to increase in number and density toward Descemet's membrane, masking the peripheral endothelium. The control corneas presented a normal microstructure apart from dust-like granular deposits in the periphery. Conclusions: In vivo confocal microscopy is a useful tool for evaluating the corneal microstructure when a Kayser-Fleischer ring is clinically present. The ring consists of granular, bright particles that increase in density toward Descemet's membrane, and is associated with a decreased number of keratocytes and peculiar dark, round areas in all stromal layers, probably a sign of corneal damage. When the ring is not visible in subjects with Wilson's disease, changes to the corneal microstructure are insignificant.


RESUMO Objetivo: Avaliar, ao nível microestrutural, através de microscopia confocal in vivo a lazer, 12 córneas com anel de Kayser-Fleischer visível ao exame da lâmpada de fenda e compará-las com 12 córneas clinicamente normais de indivíduos com idades correspondentes aos pacientes com doença de Wilson e sintomas neurológicos. Métodos: O estudo incluiu 12 indivíduos com doença de Wilson e sintomas neurológicos (24 córneas). Doze córneas apresentavam clinicamente o anel clássico de Kayser-Fleischer e as outras 12 serviram como controle. Todos os pacientes foram submetidos a um exame clínico abrangente e a uma análise microestrutural subsequente utilizando microscopia confocal in vivo de varredura a laser. Os principais resultados observados foram: aumento da espessura da córnea, diminuição do número de células, aumento de resíduos/depósitos específicos e microestrutura atípica. Resultados: Clinicamente, todos os indivíduos com anel de Kayser-Fleischer (12 olhos) apresentaram achados similares da córnea e pressão intraocular normal. Dois indivíduos também apresentaram uma catarata de girassol típica e diminuição da acuidade visual. Todos os olhos do grupo controle apresentaram acuidade visual, pressão intraocular e aparência corneana normais. A microscopia confocal in vivo com varredura a laser revelou achados semelhantes em todas as córneas afetadas. O número de ceratócitos no estroma anterior era menor, 17.380/mm3 (22.380/mm3 no grupo controle), e entre eles foram identificadas áreas escuras arredondadas "vazias". Essas zonas escuras eram generalizadas e similares em todas as córneas examinadas e em todas as camadas da córnea. No estroma posterior periférico, havia presença de depósitos granulares brilhantes e com aparência de pó que tendiam a aumentar em número e densidade no sentido da membrana de Descemet, mascarando o endotélio periférico. As córneas controle apresentaram estrutura normal, com exceção de depósitos granulares com aparência de pó na periferia. Conclusões: A microscopia confocal in vivo é uma ferramenta útil para a avaliação da microestrutura da córnea quando o anel de Kayser-Fleischer está clinicamente presente. O anel é constituído de partículas granulares brilhantes com densidade aumentada no sentido da membrana de Descemet. Sua presença está associada com uma diminuição do número de ceratócitos e com áreas circulares escuras "peculiares" em todas as camadas estromais, que representam, provavelmente, um sinal de dano da córnea. Quando o anel não está clinicamente visível, a estrutura da córnea in vivo encontra-se insignificantemente alterada.

ABSTRACT

ABSTRACT We report intraoperative finding of Granular Corneal Dystrophy Type-1 (GCD1) deposits after stromal pneumodissection in deep anterior lamellar keratoplasty (DALK) in a 61-year-old female. Pneumodissection was performed from the center to the periphery of the cornea, characterizing a big bubble type 1 technique which dissects the deep stroma from the predescemetic layer. After stromal removal, persistence of whitish deposits inside the predescemetic layer was noted. During post-operative evaluation, anterior biomicroscopy and anterior segment optical coherence tomography showed granular opacities between the patient's Descemet's membrane and the donor cornea, suggesting possible involvement of the predescemetic layer in GCD1. This may require the surgeon's attention to choose between DALK keratoplasty or penetrating keratoplasty.


RESUMO Relatamos o achado intraoperatório de persistência dos depósitos de Distrofia Granular Tipo 1 (GCD1) após pneumodissecção estromal no transplante de córnea lamelar anterior profundo (DALK) em uma mulher de 61 anos. A pneumodissecção começou a partir do centro para a periferia da córnea, caracterizando uma big bubble tipo 1, que disseca o estroma profundo da camada pré-Descemet. Após a remoção do estroma, notamos a persistência de depósitos esbranquiçados no interior da camada pré-Descemet. Na avaliação pós-operatória, a biomicroscopia anterior e a tomografia de coerência óptica do segmento anterior evidenciaram opacidades granulares entre a membrana de Descemet e a córnea doadora, sugerindo o possível envolvimento da camada pré-Descemet na GCD1, o que pode chamar atenção do cirurgião para decidir entre manter o DALK ou converter para transplante penetrante.

ABSTRACT

PURPOSE: To report a case of anterior segment ischemia after superior and inferior rectus muscle surgery in a patient with superior rectus muscle enlargement. This is the first report in the Republic of Korea of anterior segment ischemia after two rectus muscles surgery. CASE SUMMARY: An 80-year-old male was referred to our clinic with a 3 years history of diplopia. The patient had 30 prism diopters right eye hypertropia in the primary position and downgaze limitation. The orbital computed tomography scan revealed enlargement of the right superior rectus muscle. He underwent right superior rectus recession and inferior rectus resection. On postoperative day 2, slit lamp examination revealed diffuse corneal edema, Descemet's membrane folding, an aqueous flare and a dilated pupil. Treatment with 45 mg oral steroid was initiated, and 1% prednisolone acetate and 0.5% Levofloxacin eye drops were administered. At postoperative 1 month, the patient was orthophoric in the primary position, and there was no corneal edema, pupil abnormality or aqueous flare. CONCLUSIONS: Base on the present case, the possibility of anterior segment ischemia should be considered after even two muscles surgery, and older patients with vertical muscle surgery should be considered more carefully.

ABSTRACT

Abstract We report an unusual case of a 65-year old patient that developed localized bilateral Descemet membrane detachment during non-simultaneous femtosecond laser-assisted cataract surgery (FLACS). The detachment occurred when the laser was performing the secondary incision. In the operating room, the isolate-and-release technique was used to effectively manage this complication. To the best of our knowledge, this is the first reported case of bilateral Descemet membrane detachment during FLACS.


Resumo Relatamos um caso de uma paciente de 65 anos de idade que evoluiu com descolamento de Descemet localizado bilateral durante cirurgias de catarata não simultâneas com laser de femtosegundo. O descolamento ocorreu durante a realização da paracentese pelo laser. Na sala cirúrgica, foi utilizada a técnica de "isolar e liberar" para conduzir eficazmente esta complicação. De acordo com o nosso conhecimento, esse é o primeiro relato de caso de descolamento bilateral da membrana de Descemet durante cirurgia de catarata com laser de femtosegundo.

ABSTRACT

ABSTRACT Purpose: The optical quality of the interface after deep anterior lamellar keratoplasty (DALK) using the big-bubble technique has been shown to be excellent, leading to results comparable to penetrating keratoplasty. However, there is little in the literature with respect to the controversy surrounding the preparation of the donor cornea. The purpose of this study was to evaluate visual acuity (VA) in patients with keratoconus who underwent DALK without removal of the donor graft endothelium. Methods: The records of 90 patients who underwent DALK without the removal of the Descemet membrane (DM) and endothelium were retrospectively reviewed. Data collected included uncorrected VA (UCVA) and spectacle-corrected VA (SCVA) at 7, 30, 180 days, and 1 year postoperatively. Contact lens-corrected visual acuity (CLVA) was evaluated after 1 year of the procedure. Results: UCVA was significantly better than preoperative values at 7 days (p<0.001), 30 days (p<0.001), 180 days (p<0.001), and 1 year (p<0.001) after surgery. The 1-year postoperative mean SCVA and CLVA also improved when compared with preoperative SCVA (p<0.001 for both). Conclusions: DALK utilizing donor corneas with attached Descemet membrane and endothelium results in satisfactory VA in patients with keratoconus.


RESUMO Objetivos: A qualidade óptica da interface após ceratoplastia lamelar anterior profunda (DALK) utilizando a técnica de "Big Bubble" mostrou-se ser excelente, levando a resultados comparáveis aos da ceratoplastia penetrante. No entanto, há poucos dados na literatura com respeito à controvérsia em torno da preparação da córnea doadora. O objetivo deste estudo foi avaliar a acuidade visual (VA) em pacientes com ceratocone submetidos DALK sem a remoção da membrana de descemet e endotélio do tecido doador. Métodos: Os prontuários de 90 pacientes que foram submetidos a DALK sem a remoção da membrana Descemet (DM) e do endotélio foram avaliados retrospectivamente. Os dados coletados incluíram VA sem correção (UCVA) e VA corrigida por óculos (SCVA) aos 7, 30, 180 dias, e 1 ano de pós-operatório. A acuidade visual corrigida por lente de contato (CLVA) foi avaliada após 1 ano do procedimento. Resultados: UCVA no pós-operatório melhorou após 7 dias (p<0,001); 30 dias (p<0,001); 180 dias (p<0,001); e após 1 ano (p<0,001). Ocorreu melhora da SCVA pré-operatória quando comparada com a SCVA e CLVA após 1 ano (p<0,001 para ambos). Conclusão: Transplante lamelar anterior utilizando córneas doadas com membrana de Descemet e endotélio demonstrou resultados visuais satisfatórios em pacientes com ceratocone.

ABSTRACT

ABSTRACT Purpose: To compare the effect of 20% sulfur hexafluoride (SF6) with that of air on graft detachment rates for intraocular tamponade in Descemet membrane endothelial keratoplasty (DMEK). Methods: Forty-two eyes of patients who underwent DMEK by a single surgeon (A.S.J.) at Wilmer Eye Institute between January 2012 and 2014 were identified; 21 received air for intraocular tamponade and the next consecutive 21 received SF6. The main outcome measure was the graft detachment rate; univariate and multivariate analyses were performed. Results: The graft detachment rate was 67% in the air group and 19% in the SF6 group (p<0.05). No complete graft detachments occurred, and all partial detachments underwent intervention with injection of intraocular air. The percentages of eyes with 20/25 or better vision were not different between the groups (67% vs. 71%). Univariate analysis showed significantly higher detachment rates with air tamponade (OR, 8.50; p<0.005) and larger donor graft size (OR, 14.96; p<0.05). Multivariate analysis with gas but not graft size included showed that gas was an independent statistically significant predictor of outcome (OR, 6.65; p<0.05). When graft size was included as a covariate, gas was no longer a statistically significant predictor of detachment but maintained OR of 7.81 (p=0.063) similar to the results of univariate and multivariate analyses without graft size. Conclusion: In comparison with air, graft detachment rates for intraocular tamponade in DMEK were significantly reduced by 20% SF6.


RESUMO Objetivo: Comparar as taxas de descolamento do botão endotelial com o uso de gás hexafluoreto de enxofre a 20% (SF6) em relação ao ar para o tamponamento intraocular na ceratoplastia endotelial da membrana de Descemet (DMEK). Métodos: Quarenta e dois olhos foram operados com a técnica de DMEK por um único cirurgião (A.S.J.) no Wilmer Eye Institute entre janeiro de 2012 a 2014. Os primeiros 21 olhos receberam ar para o tamponamento intraocular após o enxerto do botão endotelial e os 21 olhos seguintes receberam SF6. O desfecho primário medido foi a taxa de descolamento do botão endotelial por análise univariada e multivariada. Resultados: A taxa de descolamento do botão endotelial foi de 67% no grupo que recebeu ar vs 19% no grupo que recebeu SF6 (p<0,05). Não houve nenhum descolamento total de botão e todos os parciais foram tratados com injeção de ar intraocular. Não houve diferença estatística significativa entre os grupos em relação a AV de 20/25 ou melhor (67% vs 71%). A análise univariada demonstrou maior taxa de descolamento com o tamponamento por ar intraocular (OR 8,50, p<0,005) e com botões doadores maiores (OR 14,96, p<0,05). Na análise multivariada, incluindo gás, mas não o tamanho do botão doador, o tipo de gás usado permaneceu sendo um fator preditivo independente e estatisticamente significativo para o desfecho primário, com OR de 6,65 (p<0,05). Porém, quando o tamanho do botão doador foi incluso como covariável, o gás perdeu a sua significância como preditor de descolamento, mantendo o OR de 7,81 (p=0,063), semelhante as análises univariada e multivariada excluindo o tamanho do botão doador. Conclusão: O uso de gás hexafluoreto de enxofre a 20% (SF6) para o tamponamento intraocular reduz a taxa de descolamento do botão endotelial quando comparado ao uso de ar no DMEK.

ABSTRACT

RESUMO Objetivo: Estudar, através do exame histopatológico, a epidemiologia de ceratites fúngicas tratadas com ceratoplastia penetrante terapêutica, enfatizando a presença de cirurgia ocular prévia. Métodos: Inicialmente, o estudo foi observacional e transversal de botões corneanos provenientes de ceratoplastia penetrante no período de 2006-2015 enviados para exame histopatológico ao banco de olhos do Hospital Geral de Fortaleza. Os tecidos foram corados com Hematoxilina-eosina, PAS ou Grocott, e examinados com microscópio óptico. Foram selecionados casos com diagnóstico histopatológico de ceratite fúngica. Após a selecão, realizamos revisão de prontuários buscando idade e sexo do paciente, data(s) do(s) transplante(s) por ceratite fúngica, diagnóstico clínico précirúrgico, presença/tipo de cirurgias anteriores e/ou posteriores. Incluímos 62 botões corneanos de 55 pacientes. Resultados: A maioria dos pacientes era do sexo masculino. Apenas 7 (11,29%) casos tiveram recidiva da infecção tratada cirurgicamente. 10 (16,13%) casos possuíam cirurgia ocular prévia a ceratite fúngica tratada por transplante. Nenhum caso teve ceratite fúngica como diagnóstico clínico pré-cirúrgico. A principal forma de fungo no exame histopatológico foi forma leveduriforme isolada, seguida pela leveduriforme associada à filamentosa. O aspecto predominante da membrana de Descemet foi livre de fungos. Conclusão: Demonstramos o potencial curativo das ceratites fúngicas quando tratadas com ceratoplastia penetrante terapêutica e uma possível associação do fator cirurgia ocular prévia ao desenvolvimento dessas infecções. Características do exame histopatológico foram abordadas diferente de outros estudos que, em sua maioria, citam apenas o exame microbiológico. A dificuldade no diagnóstico clínico précirúrgico foi ressaltada, o que pode ter contribuído com a evolução dos casos estudados para tratamento cirúrgico.


ABSTRACT Objective: To study, by means of histopathological examination, the epidemiology of fungal keratitis treated with penetrating keratoplasty therapy, emphasizing the presence of previous ocular surgery. Methods: Initially, we made an observational and cross-sectional study of corneal buttons from penetrating keratoplasty in the 2006-2015 period sent for histopathological examination at the Hospital Geral de Fortaleza Eye Bank.Tissues were stained with hematoxylin-eosin, PAS or Grocott, and examined with an optical microscope. We selected the cases with histopathological diagnosis of fungal keratitis. After the selection, we carried out a review of records seeking for age and sex of patients, date(s) of the graft(s) made to treat fungal keratitis, preoperative clinical diagnosis, presence/type of earlier and/or subsequent surgeries.We included 62 corneal buttons from 55 patients. Results: Most patients were male. Only 7 (11.29%) cases had recurrence of the surgically treated infection. 10 (16.13%) cases had eye surgery prior to fungal keratitis treated by transplant. No cases had fungal keratitis as preoperative clinical diagnosis.The main form of fungus in histopathological examination was isolated yeast form, followed by the yeast form associated with the filamentous form.The predominant aspect of Descemet's membrane was free of fungus. Conclusion: We demonstrated the healing potential of fungal keratitis when treated with penetrating therapeutic keratoplasty and the possible association of previous eye surgery factor for the development of these infections. Characteristics of histopathological examination have been approached differently from other studies that mostly specify only the microbiological examination. The difficulty in preoperative clinical diagnosis was highlighted, which may have contributed to the evolution of the cases studied for surgical treatment.

ABSTRACT

El desprendimiento de la membrana de Descemet es una complicación infrecuente de la cirugía intraocular que puede resultar devastadora si no se diagnostica y se trata a tiempo. Habitualmente está asociado a la cirugía de la catarata, aunque tiene múltiples etiologías. Existen tratamientos muy variados, desde la simple observación hasta la queratoplastia penetrante. Se presenta una paciente femenina de 66 años de edad, con antecedentes de salud, quien fue operada de catarata del ojo derecho por la técnica de facoemulsificación con implante de lente intraocular de cámara posterior sin complicaciones aparentes durante la cirugía. En el posoperatorio presentó a las 24 horas edema corneal tres cruces con tensión ocular normal, el cual se mantuvo durante la primera semana a pesar del tratamiento intensivo con cloruro de sodio hipertónico y antinflamatorios esteroideos. No se recogieron alteraciones del endotelio corneal previas a la cirugía. En las imágenes de Scheimpflug del pentacam se observó desprendimiento de la membrana de Descemet en distintos puntos. Se realizó neumopexia y a las 24 horas la córnea se encontraba transparente(AU)


Descemet´s membrane detachment is an uncommon complication of the intraocular surgery that can be devastating if it is not diagnosed and treated on time. It is usually associated to cataract surgery, although has multiple etiologies. Treatments vary from the simple observation to the penetrating keratoplasty. This is the case of a 66 year-old woman, with a history of health problems, who was operated on of cataract in her right eye through the phacoemulsification technique with posterior chamber intraocular lens implantation without apparent complications during surgery. After 24 hours, she presented with corneal edema, three crosses and normal ocular pressure. She remained with the same condition during the first week despite treatment with hypertonic sodium chloride and steroid anti-inflammatory drugs. There were no alterations in the corneal endothelium before surgery. Scheimpflug images in Pentacam showed Descemet´s membrane detachment in several sites. It was decided to apply pneumopexia which rendered transparent cornea after other 24 hours(AU)
