Retinal racemose hemangioma with retinal artery macroaneurysm: Optical coherence tomography angiography (OCTA) findings

PURPOSETo describe a rare case of retinal racemose hemangioma (RRH) with retinal artery macroaneurysm (RAM) and its optical coherence tomography angiography (OCT-A) finding before and after treatment. OBSERVATIONSCongenital arteriovenous (AV) communications or RRH is a rare developmental anomaly associated with various ocular conditions. RRH alone is usually asymptomatic, and vision loss occurs when associated with other ocular complications like retinal vein occlusion, hemmorage, macular edema and macroaneurysm. In this communication we describe a case of a 44-year-old female having RRH who presented with active, leaking RAM with subretinal hemmorage. OCT-A through the lesion demonstrated an active aneurysm which on subsequent treatment with anti VEGF and focal laser photocoagulation showed involution of aneurysm. CONCLUSIONS AND IMPORTANCERRH is usually asymptomatic and may be associated with vision threatening ocular complications like RAM. OCT-A helps in giving additional dynamic blood flow information in RAM.
