Abstract

Macular branch retinal vein occlusion (BRVO), a type of retinal vein occlusion, is rarely recognised as a distinct entity. Macular BRVO has unique clinical features and different natural courses than the major BRVO. We report a case of a young patient with macular BRVO with macular oedema who was successfully treated with intravitreal ranibizumab injection. A 43 year-old Chinese man with no underlying medical illness presented with 2 weeks history of left eye painless reduced central vision which was worsening over time. On examination, his left eye visual acuity was 6/30 and Amsler chart drawing showed a lower central scotoma. Dilated fundus examination found marked flame-shaped retinal hemorrhages with cotton wool spot over the superior macular area bounded superiorly by superior arcade and macular thickening. An optical coherence tomography revealed cystoid macular oedema; and fundus fluorescein angiography showed occlusion of a small venous branch draining a superior part of macula to superior temporal venous arcade. A complete medical investigation found that he has hypertriglyceridemia and he was managed accordingly. His vision had improved to 6/6 after receiving 3 injections of intravitreal ranibizumab with no residual central scotoma and complete resolution of macular oedema.
