A man in his 40s was referred for visual complaints in his right eye. His medical and ocular histories were otherwise unremarkable. His visual acuity was 20/50 OD and 20/20 OS. In the right eye, ultra-widefield color photography revealed sectorial myelinated fibers with associated multiple retinal vascular telangiectasias and retinoschisis (Figure, A), while no clinically significant changes were noted in the left eye. The retinoschisis was mostly flat and colocalized with telangiectasias, which may cause exudation and eventually exudative retinoschisis.1 The right macula was affected by an epiretinal membrane. Widefield optical coherence tomography angiography provided a detailed view of telangiectasia within a region of retinal hypoperfusion (Figure, B).
