Subretinal neovascularization following ruptured retinal arterial macroaneurysm: case report

ABSTRACT

A 51-year-old black woman was referred to our Retina Clinic for evaluation of loss of vision in her left eye. She was previously diagnosed with a ruptured retinal arterial macroaneurism (RAM) in the same eye. The ophthalmoscopic examination of the affected eye disclosed a subretinal lesion with some hemorrhage and exudation in the same area previously diagnosed with ruptured RAM. Fluorescein angiography revealed a gradually hyperfluorescent net of vessels located in the subfoveal region, consistent with the diagnosis of subretinal neovascular membrane. In this paper we stress the possibility of subretinal neovascularization following a ruptured RAM, even as a rare event.

RESUMO

Paciente de 51 anos foi encaminhada ao Setor de Retina para avaliação de perda visual no olho esquerdo. A paciente apresentava o diagnóstico prévio de macroaneurisma arterial retiniano (MAR) rôto no referido olho. O exame oftalmológico revelou lesão sub-retiniana hemorrágica associada à exsudação na área previamente diagnosticada com MAR. A angiofluoresceinografia revelou hiperfluorescência gradual localizada na região subfoveal, consistente com o diagnóstico de membrana neovascular sub-retiniana (MNSR). Nosso artigo aponta para a possibilidade, embora rara, da formação de uma MNSR após MAR rôto.
