Multimodal imaging of congenital retinal macrovessel with secondary foveal hypoplasia.

Congenital retinal macrovessel (CRM) is defined as a large aberrant blood vessel that traverses through the central macula. It can have large tributaries extending on both sides of the horizontal raphe. The condition is typically asymptomatic. However, visual loss may be reported in case of associated branch retinal artery occlusion, cavernous haemangioma, retinal artery macroaneurysm, retinal deep capillary ischaemia, retinal detachment and vitreous haemorrhage. However, association of CRM and foveal hypoplasia has rarely been reported.We report multimodal imaging in a patient who was presented with visual loss due to foveal hypoplasia secondary to CRM.
