Demographic Characterization of Uveal Melanoma Population in Portugal

INTRODUCTION: Uveal melanoma (UM) is the most common intraocular tumor and although rare, remains a clinical challenge for ocular oncologists. Therapeutic options have evolved throughout the years, focusing in eye-conserving modalities. However, long-term survival remains unchanged. Advances in early diagnosis and treatment represent a step forward in improving patients’ outcomes and survival. The purpose of th...

Incidence and Predictors of Radiation Retinopathy after I125 Plaque Brachythera...

INTRODUCTION: Plaque brachytherapy is an established modality for the treatment of eligible choroidal melanomas. Radiation retinopathy (RR) is a known complication of brachy- therapy, responsible in part for the loss of vision after treatment. We aim to present the first report on the incidence and the predictors of radiation retinopathy after the treatment of choroidal mela- nomas in the Portuguese Ocular Onco...

Epiretinal Membrane Detection in Optical Coherence Tomography Retinal Images Us...

Epiretinal membrane (ERM) is an eye disease that affects 7% of the world population, with a higher incidence in people over 75 years old. If left untreated, it can lead to complications in the central vision, resulting in severe vision loss. Early detection is important for progress follow-up, treatment monitoring, and to avoid total vision loss. Optical coherence tomography, a non-invasive retina imaging techn...

Neurodegeneration in systemic lupus erythematosus: layer by layer retinal study...

Systemic lupus erythematosus (SLE) is a chronic, autoimmune and multisystemic disease. Recent studies with functional and structural magnetic resonance imaging and cognitive tests report an unexpectedly high frequency of central nervous system involvement, even in patients with asymptomatic SLE. The purpose of this study was to identify early signs of retinal neurodegeneration by comparing the thickness of the ...

LINFOMA INTRAOCULAR PRIMÁRIO – CASO CLINICO

Introdução: O Linfoma Intraocular Primário é uma neoplasia rara que pode envolver o vítreo, retina, epitélio pigmentar da retina, membrana de Bruch e o nervo ótico. Manifesta-se de forma independente ou associado ao linfoma do sistema nervoso central e frequentemente manifesta-se como uma uveíte posterior de difícil tratamento. Esta forma de linfoma é um dos tumores intraoculares mais desafiantes de se diagnost...

EPISCLERAL BRACHYTHERAPY IN PORTUGAL:

OBJECTIVOS: Avaliar o desempenho do Centro de Referência Português de Onco-Oftalmologia no que diz respeito ao controlo local, taxas de sobrevida, taxas de metastização e efeitos secundários da Braquiterapia Episcleral (BTE), e comparar estes resultados com a literatura. MATERIAL E MÉTODOS: Estudo prospectivo e consecutivo que incluiu os doentes referenciados ao Centro de Referência de Onco-Oftamologia por mela...

Choroidal thickness changes in systemic lupus erythematosus patients

Purpose: To compare choroidal thickness (CT) between patients with systemic lupus erythematosus (SLE) without ophthalmologic manifestations and a control group. To study the effects in CT of disease duration, activity index, medication and systemic comorbidities. Methods: Cross-sectional study where spectral-domain optical coherence tomography with enhanced depth imaging was used to measure CT in 13 locations, ...

Conjunctival melanoma: association of cyclooxygenase-2 tumor expression to prog...

PURPOSE: Conjunctival melanoma is a rare but potentially lethal tumor. Its biologic profile is still largely unknown, with recent studies aiming at establishing histopathological and genetic tumor profiles. The aim of this study was to analyze the association between clinicopathological characteristics and tumor expression of cyclooxygenase-2 (COX-2) to prognosis, assessing its usefulness as a possible prognost...

Choroidal Melanoma

Choroidal melanoma is the most common primary intraocular malignant tumor in adults. None of the different treatments available offers advantages of survival, resorting more and more to conservative treatments such as brachytherapy, which has been available in Portugal since 2013. In this article we review the clinical characteristics, risk factors, diagnosis, complementary exams and therapeutic options in chor...
