Frosted branch angiitis (FBA), a relatively rare condition, is a retinal perivasculitis with severe retinal vessel sheathing resembling the frosted branches of a tree. It can be a Primary Idiopathic FBA or Secondary FBA when associated with systemic conditions like viral infections, sarcoid etc. Primary frosted branch angiitis causes characteristic florid, translucent retinal perivascular sheathing of both arterioles and venules in association with variable uveitis, retinal edema and visual loss. Additional retinal findings may include intraretinal haemorrhages, hard exudates, and serous exudative detachments of the macula and periphery. It is unclear whether retinal frosted branch angiitis is a distinct clinical syndrome or a clinical sign increasingly recognised in a number of inflammatory conditions. Hence, retinal frosted branch angiitis may be more of a sign than a separate disease. Treatment is usually with corticosteroids and normally leads to a good visual recovery. We report a case of primary unilateral frosted branch angiitis with large areas of capillary drop out and severe macular edema. It was successfully managed with intravitreal injection of Dexamethasone Implant (Ozurdex TM) in conjunction with a very short course of systemic steroids. To our knowledge, this is the first documented case of primary unilateral FBA treated with systemic steroids and an intravitreal dexamethasone implant.
