The patient is a 49-year-old male that presented to the emergency department with complaints of bilaterally decreased vision, particularly in dim illumination, and eye pain.
His previous medical history was remarkable for hemodialysis due to renal vascular disease and chronic hepatitis due to severe alcoholism; there was also a history of long-standing poor visual acuity in the OD due to a central retinal vein occlusion (CRVO) many years ago.
