ABSTRACT
Abstract We report the case of a 31-year-old woman who presented with a nine-month history of blurred vision in her left eye. Slit-lamp examination and optical coherence tomography showed four cystic masses hanging at the pupillary margin of the left eye. Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser photocoagulation was used to rupture the wall (cystotomy), drain the cyst content and shrink the remnants of the pigment epithelium, using laser parameters at the lowest effective levels. The patient's best corrected visual acuity improved significantly after treatment. Despite the increase of pigment at anterior chamber angle, no complication was observed during 6 months of follow up. This is the first report to describe frequency-doubled Nd:YAG laser (532 nm) photocoagulation as a therapeutic option for patients with symptomatic primary IPE cysts at pupillary margin.
Resumo Relatamos o caso de uma mulher de 31 anos com queixa de visão turva no olho esquerdo. Exame em lâmpada de fenda e tomografia de coerência óptica mostraram quatro lesões císticas nas margens da pupila esquerda. O laser do tipo Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) de dupla-frequência foi o tratamento de escolha para romper a parede (cistotomia), drenar o conteúdo do cisto e encolher os remanescentes do epitélio de pigmentar utilizando os menores parâmetros efetivos. Após o tratamento do olho comprometido, sua acuidade visual melhorou consideravelmente. Apesar do aumento da pigmentação no ângulo da câmara anterior, nenhuma complicação foi observada durante 6 meses de acompanhamento. Este é o primeiro relato que descreve o laser de Nd:YAG de dupla frequência (532 nm) como uma opção terapêutica para pacientes com cistos irianos primários do epitélio pigmentar sintomáticos na margem pupilar.

ABSTRACT Ocular metastasis is relatively uncommon, with a reported incidence of approximately 8%, according to the results of autopsy evaluation. The majority of ocular metastases are located within the choroid, while metastatic tumors affecting the iris are rare. Metastatic tumors may manifest as stromal nodules or ill-defined iris thickening, or they may present with nonspecific features such as pain, iridocyclitis, and hyphema. Here, we describe three patients with iris metastasis and discuss the diagnostic challenges and unusual findings associated with these cases.
RESUMO A maioria das metástases oculares do câncer sistêmico são encontrados na coroide. As metástases para a íris são incomuns, podendo se manifestar como nódulo estromal, espessamento de íris de limites mal definidos ou como uma iridociclite ou hifema. Relatamos 3 pacientes com lesão de íris e história pregressa de câncer sistêmico. Enfatizamos a dificuldade no diagnóstico e raridade dessas lesões comparando com relatos anteriores.

O artigo apresenta uma análise histológica de um caso de melanoma recidivado de íris após sete meses da iridociclectomia, em uma paciente de 45 anos. Após enucleação, o exame histopatológico do globo ocular demonstrou a persistência de um pequeno fragmento do tumor no coto da íris remanescente, evoluindo para recorrência da neoplasia. O caso traz dados para uma discussão sobre a cirurgia conservadora de melanomas oculares, visando uma postura analítica dentro do espírito da Medicina Baseada em Evidência. Um caso raro, com documentação apenas do ponto de vista histopatológico, que motiva a utilização destes achados na discussão do assunto. A não contiguidade do que restou do tumor com as tumorações da recidiva fala em favor da disseminação e proliferação de células neoplásicas nas cirurgias conservadoras.
The article presents a histologic study of a rare recurrent iris melanoma seven months after iridocyclectomy, in a 45-year-old female patient. After enucleation, the histopathological examination of the ocular globe demonstrated the persistence of a small tumor fragment in iridectomy stump, developing the neoplasia recurrence. The case brings data for a discussion about the conservative surgery of ocular melanomas and an analytical position of Evidence Based Medicine. A rare case, with documentation only histopathologic, motivates the use of this finding into the subject matter. The distance of what remained from the tumor with the recurrent tumors reinforces the dissemination and proliferation of neoplastic cells in the conservative surgeries.
ABSTRACT
Objective To probe the significance of application of ultrasound biomicroscopy (UBM) in the diagnosis and management of the iris and ciliary tumors. Methods UBM (Mode 840, Humphrey, 50 MHz 5 mm?5 mm) was done in 34 cases (35 eyes) of iris and ciliary body tumors, and some of the affected eyes underwent B scan or Doppler ultrasound and CT scan. Histopathological examination of the resected tumor tissues was performed in 21 eyes of the operation. Results Among this series of 35 eyes with iris and ciliary body tumors detected by UBM, the characteristics of locality and solidity of the tumors, i,e., anterior chamber in plantation cyst, cyst behind the iris, and solid tumors of iris and ciliary body, of 21 eyes undergone surgical treatment revealed the same results both in UBM and histopathological examinations. Conclusion UBM can supply precise informations in diagnosis and treatment of tumors of iris and ciliary body.
