This 67YO female has a history of branch retinal vein occlusion (BRVO) in her left eye. Asymptomatic degenerative retinoschisis was also present bilaterally. Vision was 20/33. She had received prior scatter laser and intravitreal injections about 3 years earlier.
Fortunately, all findings remained stable despite loss to follow-up due to the COVID pandemic.
Clarus 500 wide field imaging shows mild inferotemporal tortuosity with collateral vessels within the involved quadrant. Prior scatter laser scarring for secondary retinal neovascularization, along with prior barrier laser around the posterior edge of the schisis cavity, is noted.
Canon Xephilio S1 OCT angiography highlights the collateral vessels and more peripheral retinal nonperfusion. Xephilio B-scan shows some inferotemporal macular edema, and just catches the more distal inferotemporal schisis.
