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

Resumo Descrição de relato de caso de paciente com ceratocone (KC), Distrofia Endotelial de Fuchs (DEF) e catarata concomitantes com descompensação corneana submetido a Ceratoplastia Lamelar Posterior pela técnica Descemet's Membrane Endothelial Keratoplasty (DMEK) associado a facoemulsificação com implante de lente intraocular (LIO). Observou-se aplanamento corneano significativo no pós-operatório e acuidade visual final sem correção de 20/25 . Destaca-se a possibilidade do DMEK como alternativa à Ceratoplastia Penetrante (Penetrating Keratoplasty - PK) em casos de DEF e KC associados. Aplanamento corneano pode ocorrer neste grupo de pacientes, o que pode resultar em imprevisibilidade refracional no cálculo do poder da LIO ao se optar por facectomia combinada. Neste relato, apesar da modificação da curvatura corneana após cirurgia combinada de DMEK com facectomia, a acuidade visual final sem correção foi satisfatória, demonstrando a possibilidade de sucesso desta abordagem na coexistência de DEF, KC e Catarata. Entretanto, a possibilidade de mudança significativa na curvatura corneana deve ser considerada em pacientes com KC, edema de córnea secundário a DEF e catarata, na decisão de cirurgia simultânea ou em dois tempos.


Abstract This is a case report of a patient with concomitant Keratoconus (KC), Fuchs Endothelial Dystrophy (FED) and cataract with corneal decompensation submitted to Posterior Lamellar Corneal surgery (Descemet's Membrane Endothelial Keratoplasty - DMEK) associated with phacoemulsification with intraocular lens (IOL) implantation. Corneal flattening and uncorrected visual acuity of 20/25 was observed in the postoperative period. We reasure the viability of DMEK as an alternative to Penetrating Keratoplasty (PK) in cases of associated DEF and KC associated. Changes in corneal curvature may occur in this group of patients and lead to the possibility of refractive unpredictability in IOL calculation when performing a combined cataract surgery. Despite unexpected corneal flattening, satisfactory final visual acuity was achieved, demonstrating the possibility of success of this approach in the coexistence of the three conditions. Nonetheless, the possibility of corneal curvature changes should be considered in patients with KC and corneal decompensation due to FED in decision making, regarding simultaneous or sequential surgical approach.

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

RESUMO O DSAEK (Descemet stripping automated endotelial Keratoplasty) é um dos procedimentos de escolha para tratamento das doenças que acometem o endotélio corneano. Apesar do sucesso terapêutico, o procedimento pode induzir uma hipermetropia residual. Em média a refração se estabiliza em um perído que varia de 6 a 12 meses após o transplante. O objetivo desse relato é descrever a evolução dessa opção terapêutica utilizada em um paciente de 54 anos portador de Distrofia de Fuchs. O paciente foi submetido ao transplante de córnea (DSAEK) e a remoção do cristalino no mesmo tempo cirúrgico o que resultou em hipermetropia residual. Após 3 anos de acompanhamento apresentava-se com a melhor visão corrigida de 20/20 (Snellen) no olho operado com uma refração de +3,25 -1,00 (5º). Optou-se por realização de LASIK (Laser assisted in situ Keratomileusis) hipermetrópico, obtendo um resultado visual satisfatório.


ABSTRACT DSAEK (Descemet stripping automated endothelial keratoplasty) is one of the options for corneal endothelium disease, which in some patients can result in a residual hyperopia after the procedure. Usually 6 to 12 months after corneal transplantation refraction is already stable. This report describes a therapeutic option used in a 54 years old patient with Fuchs' endothelial dystrophy submitted to cataract and corneal transplant that resulted in residual hyperopia, three years after the procedure the best corrected vision was 20/20 with a refraction of +3.25 -1.00 (5 º) treated with Hyperopic - LASIK (Laser-assisted In Situ Keratomileusis) with satisfactory visual result.

ABSTRACT

Two blind persons received corneal transplants from a single donor who showed no signs of rabies before he died. One of the recipients, a young girl, died 16 days later of rabies and the other recipient survived. We discuss the possible mode of transmission of rabies to the first recipient and the management of the second recipient.

ABSTRACT

A 20-year-old patient, diagnosed with posterior polymorphous corneal dystrophy, developed corneal edema for which he underwent Descemet membrane endothelial keratoplasty with a stromal rim (DMEK-S) in the right eye. No intra- or postoperative complications were noted. At the last follow-up 2 years and 9 months after the procedure, the best corrected visual acuity was 1.0 and endothelial cell density declined from 3533 cells/mm2 to 1012 cells/mm2. Despite the endothelial cell loss, DMEK-S appears to be a good alternative to other surgical techniques for the treatment of corneal endotheliopathies, and it may be of benefit to young patients.

ABSTRACT

PURPOSE: To report two cases of femtosecond laser-assisted small incision deep lamellar endothelial keratoplasty (DLEK) for patients with corneal endothelial decompensation by Fuchs dystrophy and glaucoma METHODS: Femtosecond laser (IntraLase(R); IntraLase Corp., Irvine, CA) with 15 kHz of repetition rate, was used for a 9.5 mm diameter by 400 micrometer thickness donor corneal lamellar dissection. RESULTS: In Case 1, the graft was clear and compact without interface haze, Orbscan showed smooth and regular corneal surface, specular microscopy was unremarkable without sign of corneal endothelial damage, and Optical coherence tomography showed uniform graft well attached to recipient stroma with minimal interface reflection at 2 months postoperation. In Case 2, the graft was clear and compact with minimal interface haze at 1 month postoperation. Femtosecond laser-assisted small incision DLEK was safe and technically feasible in our cases; however, further evaluation is required to determine long-term effects.

ABSTRACT

Combined procedure was performed in 25 eyes and triple procedure in 32 eyes of Fuchs' dystrophy. Pre-operative visual acuity was 20/100 or less in 63.2% of eyes. The graft was clear in 76% of combined procedure and in 97% of triple procedure eyes. Post-operative visual acuity of 20/40 or better was obtained in 57.9% of eyes. The common cause of graft failure was allograft reaction. The other causes attributable to visual failure were opacification of posterior capsule, secondary glaucoma, macular degeneration and pre-existing glaucomatous cupping. Intraocular lens insertion at the time of surgery helps in rapid visual rehabilitation.
