Indications for eye removal over a 13-year period at an ophthalmology referral center in São Paulo, Brazil / Indicações para remoção ocular ao longo de um período de 13 anos no centro de referência oftalmológica em São Paulo, Brazil

ABSTRACT Purpose: To analyze the indications and types of eye removal at Latin America's highest-volume ophthalmic reference center in São Paulo, Brazil. Methods: A retrospective analysis was conducted of surgical pathological reports in the electronic database of the Ophthalmology Department of the Universidade Federal de São Paulo Hospital of patients who underwent eye-removal procedures between January 2000 and December 2012. Results: A total of 412 cases met the inclusion criteria for this study. The most common indications for eye removal were ocular melanoma and retinoblastoma, representing 35.4% and 31.1% of the total cases, respectively. Other frequent indications included endophthalmitis (6.3%), nonspecific inflammation (4.1%), squamous cell carcinoma (3.6%), panophthalmitis (3.4%), and phthisis bulbi (1.2%). The remaining indications accounted for 14.8% of all cases, with each accounting for <1% of the total cases. Enucleation was the most common eye-removal procedure seen in our study. Conclusions: The two most common indications for eye removal were ocular melanoma and retinoblastoma. Alternative treatment options are effective in limiting the need for eye removal but are constrained by our public center's so cioeconomic context.

RESUMO Objetivo: Analisar os tipos e indicações para a remoção dos olhos no maior centro de referência oftalmológica da América Latina em São Paulo, Brasil. Métodos: Revisão retrospectiva de laudos cirúrgico patológico em uma base de dados eletrônica do Departamento de Oftalmologia do Hospital da Universidade Federal de São Paulo. Foram analisados pacientes submetidos ao procedimento de remoção oftálmica no período de janeiro de 2000 a dezembro de 2012. Resultados: Um total de 412 casos estiveram de acordo com os critérios de inclusão desse estudo. A indicação mais comum para remoção oftálmica foi Melanoma ocular e Retinoblastoma, representando, respectivamente, 35,4% e 31,1% do total de casos. Outras indicações frequentes incluíam Endoftalmite 6,3%, Inflamação inespecífica 4,1%, Carcinoma escamocelular 3,6%, Panoftalmite 3,4% e Phthisis Bulbi 1,2%. O restante das indicações totalizaram 14,8% de todos os casos, sendo que cada um correspondem com menos de 1% do total. Enucleação foi o procedimento de remoção oftálmica mais comum observado em nosso estudo. Conclusão: As duas indicações mais frequentes para remoção oftálmica no centro oftalmológico de referência do Brasil foi melanoma e retinoblastoma. Opções terapêuticas alternativas são efetivas para limitar a necessidade da remoção ocular, porém são restritos devido ao contexto socioeconômico de nossa população.

Condutas para reparação da cavidade anoftálmica no Brasil / Trends on anophthalmic socket repair in Brazil

OBJETIVOS: Avaliar as condutas mais utilizadas no tratamento da cavidade anoftálmica no Brasil, comparando-as com a realidade mundial. MÉTODOS: Estudo exploratório, usando questionário eletrônico enviado pela Internet para oftalmologistas membros da Sociedade Brasileira de Cirurgia Plástica Ocular, Vias Lacrimais e Órbita - SBCPO. As respostas obtidas foram avaliadas por meio de análise de aderência, utilizando o teste do Qui-quadrado. RESULTADOS: Foram recebidos 75 questionários respondidos. Cinquenta e três por cento dos entrevistados tratam cavidade anoftálmica frequentemente e o implante de esfera de polimetilmatacrilato, de 18 mm de diâmetro, é o usado pelos entrevistados na maioria das cirurgias, sendo revestido principalmente com esclera (92%). Apenas sete entrevistados já utilizaram implante acoplado com prótese externa. Oitenta e dois por cento dos entrevistados usam a técnica do enxerto dermoadiposo. O acompanhamento destes pacientes é feito semestralmente pela maior parte dos entrevistados. CONCLUSÃO: O tratamento da cavidade anoftálmica no Brasil geralmente é feito usando a esfera de polimetilmetacrilato, de diâmetro 18 milímetros. Implantes acoplados dificilmente são usados.

PURPOSE: To determine the most common approach to repair the anophthalmic socket in Brazil, and to compare the data with the trends in other countries. METHODS: Exploratory study using electronic questionnaire sent by Internet to ophthalmologists members of the Brazilian Orbit and Oculoplastic Society (SBCPO). The received answers were analyzed by adhesion analysis, using Chi-square test. RESULTS: We received 75 answered questionnaires. Fifty-three per cent of the respondents frequently treat anophthalmic socket and use the 18 mm diameter polymethylmethacrylate sphere in the majority of the surgeries, mainly covered by sclera (92%). Only seven interviewees had used integrated implants with pegging procedure. Eighty-two per cent of the ophthalmologists use the dermolipid graft to reconstruct the anophthalmic socket. They also follow the patients bi-annually. CONCLUSIONS: The treatment of anophthalmic socket in Brazil generally involve polymethylmethacrylate sphere with 18 mm diameter. Pegging procedure is uncommon between us.

Fifteen-year trends in indications for enucleation from a tertiary care center in South India.

Aim: To analyze the trends in clinicopathologic indications for enucleations over a 15-year period. Materials and Methods: Clinicopathologic details of all eyes that underwent enucleation from January 1996 to December 2010 were drawn up from a computerized database. The study was divided into three periods of 5 years each and comparison tables for each cause of enucleation during these periods were generated. Chi-square test was used to compare proportions. Results: Out of a total 1467 enucleations performed during the study period, 693 (46%) were attributable to retinoblastoma, 189 (12.5%) to uveal melanoma, 228 (15%) to trauma, and 149 (10%) to phthisis bulbi. Intraocular tumors accounted for more than 63% of all enucleations performed. Over the three time periods, proportion of enucleations secondary to retinoblastoma increased from 38% in the 1st period to 58% in the 3rd period (P < 0.001). Enucleations for trauma showed statistically significant reduction in trends over the three periods (24% in the 1st period vs. 4.4% in the 3rd period, P < 0.001). Similar trends were also seen in the proportion of enucleations due to intractable glaucoma and chronic uveitis. The absolute number of enucleations secondary to retinoblastoma out of the total cases seen during the study period did not change over the three periods (range 51–60%). Conclusion: Intraocular tumors were the commonest indications for enucleation in our patient population despite the availability of globe-conserving treatments such as chemotherapy and radioactive plaques. We observed increasing trends in the proportion of enucleations due to retinoblastoma and reduction of enucleations secondary to trauma, chronic uveitis, and glaucoma.

Extrusão dos implantes em portadores de cavidade anoftálmica / Anophthalmic cavity and implant extrusion

OBJETIVO: Avaliar as características dos portadores de cavidades anoftálmicas que desenvolveram extrusão do implante. MÉTODOS: Estudo retrospectivo, observacional, tendo sido avaliados 37 portadores de cavidade anoftálmica que tiveram extrusão do implante de cavidade, na Faculdade de Medicina de Botucatu-UNESP. RESULTADOS: As extrusões ocorreram em cavidades enucleadas ou evisceradas, a maioria delas submetidas a cirurgia em decorrência de phthisis bulbi ou trauma, em geral de 1 a 2 anos após a cirurgia inicial. A deiscência precedeu a extrusão em todos os casos, tendo a extrusão ocorrido com todos os tipos de implantes empregados. CONCLUSÃO: Após a colocação de implantes de cavidade podem ocorrer complicações. A deiscência e extrusão das esferas são possibilidades que podem requerer nova intervenção cirúrgica, para a qual o paciente e o oftalmologista devem estar preparados.

PURPOSE: To evaluate the characteristics of patients with anophthalmic cavity who developed sphere extrusion. METHODS: A retrospective observational study was done evaluating 37 patients with anophthalmic cavity and sphere extrusion at the "Faculdade de Medicina de Botucatu-UNESP". RESULTS: Extrusion was observed in enucleated and eviscerated cavities. The majority of the patients had the eye removed because of phthisis bulbi or trauma and the extrusion happened 1 or 2 years after the surgery. Extrusion was preceded by conjunctival dehiscence and exposure of the sphere and occurred with all used implants. CONCLUSION: Complications after orbital implant placement are a possibility. Dehiscence and sphere extrusion may happen and another surgery would be necessary. The patient and the ophthalmologist have to be prepared for this.

A profile of destructive surgery in Nepal Eye Hospital.

This is a study profile of the patients undergoing destructive surgery in Nepal Eye Hospital over a period of 2 years (2001-2003). The rationale of the study was to know the incidence and causes for destructive surgery (enucleation/evisceration) and the measures to prevent them. Patients admitted in the ward from emergency and outpatients departments for the purpose of enucleation and evisceration were taken into this study. Their visual acuity, slit-lamp examinations, fundus evaluation were done. Most of the patients had no perception of light with painful blind eyes, panophthalmitis, endophthalmitis, staphylomas, crush injuries and malignancies. After a decision made by the surgeons in the round, a full consent was taken for the operation. Evisceration was done for cases with history of ocular infections and the rest were enucleated. Destructive operation was done for (a) saving the other eye, (b) life saving, (c) painful condition and disfigurement. The incidence of destructive surgery in Nepal Eye Hospital was 1.40%. male : female ratio was 1.41:1. The causes for destructive surgery were panophthalmitis (31.71%), painful blind eye (21.95%), endophthalmitis (14.63%), staphyloma (14.63%), retinoblastoma (12.20%) and crush injuries (4.88%). Number of evisceration (73.17%) was higher than enucleation (26.83%) as most of the cases were sequele of corneal ulcer. Enucleation was mostly seen in children and evisceration in adults. Lastly, the incidences of destructive surgery would be minimized by (a) Prompt treatment of corneal ulcers for reducing panophthalmitis (b) pre, intra, and post operative care in intra ocular surgery for reducing endophthalmitis, and (c) genetic counselling (pre marital) for reducing childhood malignancies. Decision for destructive surgery should be a team work rather than a single surgeon's opinion. It should be done under general anaesthesia or retrobulbar block. Precaution must be taken to prevent the appalling tragedy of enucleating the wrong eye by marking above on the eye to be operated or EUA prior to surgery. Last but not the least, there should be fitting of a prosthesis for cosmesis, psychological support and careful follow-up of the healthy eye.

Evaluation of the etiology of ocular globe atrophy or loss

Este estudo investigou a etiologia dos casos de atrofia e perda do globo ocular em pacientes atendidos no ambulatório de prótese buco-maxilo-facial de duas Faculdades de Odontologia do estado de São Paulo. Um total de 238 pacientes e seus prontuários foram examinados, e a etiologia e incidência dos casos de atrofia e perda do globo ocular foram avaliados considerando gênero, faixa etária, lado afetado e tipo de cirurgia oftalmológica realizada. As perdas por etiologia traumática foram as de maior incidência (57,14%), seguidas das perdas por etiologia patogênica (36,13%) e com menor incidência para as perdas por causas congênitas (5,04%). Comparando-se os gêneros, houve predominância da população masculina (61.76%; p<0,01). A faixa etária mais freqüentemente atingida foi a de 21 a 40 anos (42.01%; p<0,01). Em todas as etiologias estudadas, a cirurgia mais empregada para remoção do globo ocular foi a enucleação (66.38%; p<0,01). Houve predominância da perda do globo ocular do lado esquerdo (55.04%), mas não houve diferença estatisticamente significante.

The glass spherical hollow orbital implant: a prospective study.

OBJECTIVE: Various types of orbital implants are in use in the rehabilitation of anophthalmic patients. The latest is the expensive hydroxyapatite implant. The study objective was to evaluate the effectiveness of low cost glass spherical hollow implants, as primary and secondary implants. SETTING: St Michaels and Frazer Private Hospitals, Colombo. STUDY DESIGN AND METHOD: 65 patients had glass sphere orbital implants between 1987 and 1995; 51 primary (evisceration 46, enucleation 5) and 14 secondary (evisceration 2, enucleation 12). At 9 to 12 months follow up, patients were evaluated for mobility of implant, prosthesis mobility, lid sulcus deformity, cosmetic results and complications. RESULTS: Primary glass spherical hollow implants provide excellent mobility of the implant (92%), cosmesis (88%), prosthesis mobility (67%), with a low rate of complications (9.5%). Results of primary implant was superior to that of secondary (p < 0.001). CONCLUSION: Excellent results were obtained with spherical glass spheres as primary implants following evisceration.
