Branch retinal artery occlusion and non-ischemic central retinal vein occlusion due to hyperhomocysteinemia in a 14-year-old child

Abstract

A 14-year-old girl presented with sudden, painless loss of vision in the left eye. Complete ophthalmologic examination including fluorescein angiography revealed an impending central vein occlusion and a branch retinal artery occlusion inferotemporally. One month later, there was a non-ischemic central retinal vein occlusion of the same eye. Systemic evaluation led to the diagnosis of hyperhomocysteinemia. This case report underscores the importance of excluding hyperhomocysteinemia in vascular occlusive disease.
