Amniotic membrane transplantation in ocular surface diseases / Transplante de membrana amniótica em doenças da superfície ocular

Abstract Objective: To evaluate the clinical effectiveness of amniotic membrane transplantation for ocular surface reconstruction. Methods: Prospective study including 23 eyes of 21 patients who underwent amniotic membrane transplantation at Hospital de Clínicas da Universidade Federal do Paraná (HC-UFPR) and at Cirurgia e Diagnose em Oftalmologia do Paraná (CDOP) clinic, located in Curitiba, PR, Brazil, from may 2015 to july 2019. The amniotic membrane was collected from elective and term cesarean delivery, and conserved in preservation medium and glycerol 1:1, stored at -80° Celsius. The membrane was fixed on the ocular surface with 10-0 nylon, 8-0 vicryl, biological glue or a combination of these materials. Results: The ocular surface reconstruction was successful in 22 eyes (95.6%). Failure was observed only in 1 case (bullous keratopathy) in which the condition was maintained postoperatively. Patients' age ranged from 11-82 years, with a mean age of 37.4 years. There was a higher incidence in males (66.6%). A difference was perceived in the distribution of the affected eye (which was greater in the right eye - 65.2%). As for the previous ophthalmic surgery history, 12 of the 23 eyes had a positive history (52.2%). It was observed that all patients who had preoperative visual acuity assessed showed improvement or maintenance of corrected visual acuity. In the postoperative period, complications associated with the underlying disease were observed, although not particularly related to the amniotic membrane transplantation. There were not any cases of postoperative infection. Conclusions: There was an improvement in the general state of the ocular surface in almost all of the cases in which the transplant was performed. Therefore, the amniotic membrane can be considered a good alternative for reconstructing the ocular surface, as a single or supporting treatment.

Resumo Objetivo: Avaliar a eficácia clínica do transplante de membrana amniótica na reconstrução da superfície ocular. Métodos: Estudo prospectivo incluiu 23 olhos de 21 pacientes que realizaram transplante de membrana amniótica no Hospital de Clínicas da Universidade Federal do Paraná (UFPR) e na clínica de Cirurgia e Diagnose em Oftalmologia do Paraná (CDOP), localizados em Curitiba, PR, Brasil, no período de maio de 2015 a julho de 2019. A membrana amniótica foi captada a partir de parto cesárea eletivo e a termo, conservada em meio de preservação e glicerol 1:1 e armazenada a -80° Celsius. A membrana foi fixada na superfície ocular com fio nylon 10-0 ou vicryl 8-0 e/ou cola biológica. Resultados: A idade dos pacientes variou de 11-82 anos, com média de 37,4 anos. Houve maior incidência no sexo masculino (66,6%). Ocorreu diferença na distribuição do olho acometido (maior no olho direito - 65,2%). Quanto à história de cirurgia oftalmológica prévia, 12 dos 23 olhos tinham história positiva (52,2%). Observamos que nos pacientes em que foi possível a avaliação da acuidade visual pré-operatória, todos apresentaram melhora ou manutenção da acuidade visual. No pós-operatório foi observado complicações associadas à doença de base e não propriamente ao transplante de membrana amniótica. Não foram registrados casos de infecção pós-operatória. Conclusão: Houve melhora do estado geral da superfície ocular em quase totalidade dos casos em que o transplante foi realizado. Portanto, a membrana amniótica pode ser considerada uma boa alternativa para reconstrução da superfície ocular, como tratamento único ou coadjuvante.

Combined transscleral fixation of an artificial iris prosthesis with an intraocular lens / Combinação de fixação transescleral de prótese de íris artificial com lente intraocular

ABSTRACT Post-traumatic aniridia combined with aphakia may be seen after globe injury. Aside from esthetic aspects, partial or total loss of the iris tissue may also be related to various degrees of glare and photophobia. Such patients suffer from severe visual impairment secondary to aphakia. Herein we describe a novel surgical technique for the management of an aphakic eye with traumatic aniridia for a patient who underwent transscleral fixation of a custom-tailored artificial iris prosthesis combined with a rigid intraocular lens (IOL). Tight suturing of the IOL haptic eyelets on the silicone iris prosthesis and fixation of such a complex to the scleral wall may provide excellent cosmetic and functional outcomes in aphakic eyes with aniridia.

RESUMO Aniridia pós-traumática combinada com afacia pode ser observada após lesões do globo ocular. Além do ponto de vista estético, a perda parcial ou total do tecido da íris também pode estar relacionada com vários graus de ofuscamento e fotofobia. Estes pacientes sofrem de deficiência visual grave secundária a afacia. Relata-se uma técnica cirúrgica inovadora para tratamento de um olho com afacia associada à aniridia traumática que foi submetido à fixação transescleral de uma prótese de íris artificial feita sob medida combinada com uma lente intraocular rígida (IOL). A sutura das alças da IOL sobre a prótese iriana de silicone, e a fixação desse complexo na parede escleral podem proporcionar excelente resultado estético e funcional em olhos afácicos com aniridia.

Direct cyclopexy surgery for post-traumatic cyclodialysis with persistent hypotony: ultrasound biomicroscopic evaluation / Ciclopexia direta em ciclodiálise pós-traumática com hipotonia ocular persistente -acompanhamento por biomicroscopia ultrassônica (UBM)

Cyclodialysis is a relatively rare condition usually caused by ocular injury; however, it can also be caused iatrogenically during intraocular surgery. Hypotony maculopathy is the most important complication and the primary reason for visual loss. Clinical diagnosis using gonioscopy may be difficult, and ultrasound biomicroscopy (UBM) can be an alternative. There are different kinds of treatments, and the optimal one remains controversial. Here we describe a case of traumatic cyclodialysis with persistent ocular hypotony treated by direct cyclopexy, as illustrated by UBM performed before and after surgery.

Ciclodiálise é uma condição relativamente rara, geralmente devido a um trauma ocular, mas também pode ser causada iatrogenicamente como consequência de cirurgia intraocular. A maculopatia hipotônica é a complicação mais importante e a principal razão para a perda visual nessa situação. O diagnóstico clínico por gonioscopia pode ser difícil e a biomicroscopia ultrassônica (UBM) pode ser uma alternativa. Existem diferentes tipos de tratamentos e algumas controvérsias sobre a melhor opção. Neste relato, nós descrevemos um caso de ciclodiálise traumática com hipotonia ocular persistente tratado por cyclopexia direta avaliado por UBM antes e depois da cirurgia.

Introduction of Lens-angle Reconstruction Surgery in Rabbit Eyes

PURPOSE: In this study, we examined the stability of the lens-angle supporter (LAS) for accommodation restoration by comparing intraocular lens (IOL) location, after-cataract and ciliary body damage after cataract surgery in rabbits. METHODS: Eight rabbits were divided into experimental and control groups of four rabbits each. Phacoemulsification and irrigation and aspiration were performed in all rabbits. This was followed by an LAS and IOL insertion in the four experimental rabbits. In the four control rabbits, only an IOL insertion was performed. Six months after the surgery, the location of the IOL, the conditions of the lens capsule and ciliary body were evaluated using a slitl-amp examination and Miyake-Apple view. RESULTS: For the experimental group, the ultrasound biomicroscope results showed normal LAS and IOL positioning in all four cases. According to the slitlamp examination and Miyake-Apple view, the IOL was positioned at the center, with less after-cataract and damage to the ciliary body. For the control group, ultrasound biomicroscope results indicated a higher IOL position than normal, as well as a single case of IOL decentering. According to the slit-lamp examination and Miyake-Apple view, the IOL was decentered with more severe after-cataract and ciliary body damage. CONCLUSIONS: The LAS has the potential to maintain a stable IOL position while producing less after-cataract when used in lens-angle reconstruction for correction of presbyopia. Moreover, LAS implantation incurs less damage to the ciliary body.

Outcome of in-the-bag implanted square-edge polymethyl methacrylate intraocular lenses with and without primary posterior capsulotomy in pediatric traumatic cataract.

Purpose: To study the outcome of in-the-bag implanted square-edge polymethyl methacrylate (PMMA) intraocular lenses (IOL) with and without primary posterior capsulotomy in pediatric traumatic cataract. Materials and Methods: The study was undertaken in a tertiary care center. Thirty eyes of 30 children ranging in age from 4 to 16 years with traumatic cataract which underwent cataract extraction with capsular bag implantation of IOL were prospectively evaluated. Group A included 15 eyes of 15 children where primary posterior capsulotomy (PPC) and anterior vitrectomy with capsular bag implantation of square-edge PMMA IOL (Aurolab SQ3602, Madurai, Tamil Nadu, India) was performed. Group B comprised 15 eyes of 15 children in which the posterior capsule was left intact. Postoperative visual acuity, visual axis opacification (VAO) and possible complications were analyzed. Results: Best corrected visual acuity (BCVA) of 20/40 or better was achieved in 12 of 15 eyes in both groups. Amblyopia was the cause of no improvement in visual acuity in the remaining eyes. Visual axis opacification was significantly high in Group B as compared to Group A (P=0.001). Postoperative fibrinous uveitis occurred in most of the eyes in both groups. Pupillary capture was observed in one eye in each group. Conclusion: Primary posterior capsulotomy and anterior vitrectomy with capsular bag implantation of square-edge PMMA significantly helps to maintain a clear visual axis in children with traumatic cataract.

This report describes the only case in the literature of globe luxation due to traumatic cerebrospinal fluid fistula to the orbit caused by fire gun with ocular globe maintenance. E.N., female, white, 7 months, admitted with left orbitocranial injury by fire gun. Ocular globe luxation was detected with complete ocular motility restriction and absence of pupillary reflex in the left orbit. Computed tomography showed fracture of the medial orbital wall; bone fragments near the apex of the orbit and a stretched optic nerve. Surgical exploration was performed, showing liquor fistula through the ethmoid-sphenoid wall that was blocked with sponge (Gelfoam®) plus organic glue in the left orbit posterior wall, with immediate resolution of the proptosis and ocular integrity maintenance. Although controversial, maintenance of the ocular globe instead of enucleation was performed due to the integrity of the globe in this case. Despite the blindness, we considered the result to the proposed treatment excellent, once the maintenance of the ocular globe provides a good appearance and will contribute to an adequate facial bone development.

O presente estudo apresenta o único caso de luxação de globo ocular devido fístula liquórica traumática em vítima de trauma órbito-cerebral por projétil de arma de fogo com a preservação do globo ocular. E.N., feminino, branca, 7 meses, admitida com ferimento por projétil de arma de fogo em região órbito-craniana esquerda. Apresentava luxação de globo ocular esquerdo com restrição completa da motilidade ocular e reflexo fotomotor ausente à esquerda. À tomografia: fraturas da parede medial da órbita; fragmentos ósseos próximos ao ápice da órbita. Realizou-se exploração cirúrgica, evidenciando-se fístula liquórica através de fratura etmoido-esfenoidal a qual foi tamponada com esponja (Gelfoam®) e cola orgânica na parte posterior da parede medial da órbita esquerda, com regressão imediata da luxação do globo ocular, sendo o mesmo mantido íntegro. Embora controversa na literatura, optou-se pela preservação do globo ocular à enucleação, visto que o mesmo estava íntegro. Apesar da cegueira, consideramos um excelente resultado ao tratamento proposto, tendo em vista que a preservação do globo ocular provém uma boa aparência, favorecendo também o desenvolvimento ósseo da face.

Características del trauma ocular asociadas con la necesidad de cirugía retiniana de urgencia / Ocular trauma characteristics associated with urgent retinal surgery

Objetivo: Identificar las características del sistema de clasificación de lesiones mecánicas oculares más frecuentes en ojos que requieren cirugía retiniana de urgencia y evaluar su valor predictivo, para determinar su utilidad en el pronóstico temprano. Material y métodos: Se evaluaron retrospectivamente pacientes atendidos entre 1998 y 2007 y se asignaron a uno de dos grupos: 1 (con lesiones que requerían cirugía retiniana de urgencia) y 2 (sin ellas). Se determinó la proporción e intervalos de confianza (IC) de 95 % que representaba el grupo 1; se identificaron las características más frecuentes en el grupo 1 y su proporción se comparó con la del grupo 2 mediante χ2 y razón de momios. Se determinaron los valores predictivos de cada característica para identificar al grupo 1. Resultados: 238 ojos, edad promedio de los pacientes de 27.5 años; 10 ojos se asignaron al grupo 1 (4.2 %, IC 95 % = 1.65-6.75) y 228 al 2. Las características más frecuentes del grupo 1 fueron globo abierto (90 %), tipo A abierto (50 %), tipo C abierto (30 %), grado 4 (70 %) y zona III (70 %). El valor predictivo positivo fue de 60 % para trauma abierto tipo C, y menor a 50 % en el resto de las características. Conclusiones: Aunque existieron características asociadas significativamente con la necesidad de cirugía retiniana de urgencia, su valor predictivo fue insuficiente por la baja proporción de ojos que requería esta intervención, por lo que se sugiere utilizar como parámetro de referencia al globo abierto o la pérdida visual, independientemente de las lesiones existentes.

BACKGROUND: The most common features of the system for classifying ocular injuries of the eye in patients who require urgent retinal surgery were identified, and their predictive value was estimated in order to determine whether they are useful in detecting these patients. METHODS: Patients with ocular trauma between 1998 and 2007 were retrospectively evaluated and assigned to one of two groups: group 1 (with injuries that required urgent retinal surgery) and group 2 (without those injuries). The rate and 95% confidence intervals (CI) that group 1 accounted for were identified. The rate of the most common features in group 1 was identified and compared with their rate in group 2 using chi(2) and odds ratio. Predictive values of those features for detecting group 1 were calculated. RESULTS: Two hundred thirty eight eyes (mean age: 27.5 years) were included. Ten eyes were assigned to group 1 (4.2%, 95% CI 1.6-6.7) and 228 eyes were assigned to group 2. The most frequent features in group 1 were open globe (90%), type A open globe (50%), type C open globe (30%), grade 4 (70%) and zone III (70%). The positive predictive value was 60% for type C open globe, and <50% for the remaining features. CONCLUSIONS: Although some clinical features had a statistical and clinical association with the need for urgent retinal surgery, their predictive value was insufficient because the rate of eyes that required this intervention was low. The results suggest that open globe and visual loss should be used as referral criteria, regardless of the injuries found.
