Telangiectasia retiniana é um termo inicialmente proposto por Reese, em 1956. Caracteriza-se por uma anormalidade vascular retiniana, com dilatação irregular e incompetência dos vasos. E.L.S., 44 anos, sexo masculino, branco, do Rio de Janeiro, com queixa de perda progressiva da visão em olho esquerdo (OE). Ao exame observamos acuidade visual (AV) corrigida de 20/20 em olho direito (OD) e 20/100 em OE. À fundoscopia, OD normal e OE apresentando dilatação capilar e exsudatos duros com aspecto circinado na região macular. Angiografia fluoresceínica e, após o resultado, injeção intravítrea de triancinolona em OE (4mg/0,1ml). Após um mês da injeção de triancinolona a AV em OE passou a 20/40, os exsudatos duros tornaram-se mais visíveis e a angiografia mostrou diminuição do vazamento do corante. Foi possível a realização de fotocoagulação com laser. A AV final corrigida foi de 20/20 em ambos os olhos. O tratamento com laser está amplamente difundido na literatura, porém optamos inicialmente pela injeção intravítrea de triancinolona. Pode-se considerar a injeção intravítrea de triancinolona em casos de telangiectasia retiniana parafoveal com redução importante da visão e alterações muito próximas à região avascular foveal. Entretanto, os resultados em longo prazo não são conhecidos e precisam ser confrontados com as outras opções de tratamento.Retinal telangiectasis was first described by Reese, in 1956. It is an abnormality of the retinal vessels, with irregular dilation and vessel failure. ELS, 44 years old, male, white, from Rio de Janeiro. His complaining was progressive visual loss in the left eye (OS). Corrected visual acuity (VA) was 20/20 in the right eye (OD) and 20/100 in OS. Fundoscopy in OD was normal, and in OS showed capillaries dilation and hard exsudates (circinate) in macular area. After fluorescein angiogram, we performed intravitreal injection of triamcinolone acetonide (4mg/0.1ml) in OS. One month after injection, VA in OS was 20/40, hard exsudates became more visible and angiogram showed a reduction in dye leakage. Due to better visibility, we were able to perform laser photocoagulation on the affected area. Final best corrected VA was 20/20 in both eyes. Although laser treatment is widely recommended, we chose intravitreal triamcinolone injection initially due to the fact that damaged capillaries were too close to foveal avascular zone. Intravitreal triamcinolone injection can be considered in cases of parafoveal retinal telangiectasis with significant decreased vision and changes near foveal avascular zone. However, long term results are not known yet and need to be confronted with other available treatments.
