Non-ischemic Central Retinal Vein Occlusion CRVO with Venous Stasis Retinopathy.
Female, 56 years of age, 2 weeks after a hiking tour now visual complaints OD.
VA R/L cc 1.0, IOP R/L 16 mmHg. Blood values were normal.
Ophthalmoscopic picture showing venous dilation and tortuosity, retinal hemorrhages, and retinal edema.
FLA showing a delayed filling, but no areas with retinal ischemia.
OCT depicting a parapapillary retinal edema temporal of the optic nerve head (arrow). We found no macular edema.
CRVO is always a thrombotic disorder. All the available anatomical, experimental and clinical evidence in CRVO show that the actual site of occlusion in the CRV is typically in the optic nerve at a variable distance posterior to the lamina cribrosa (1). One third of patients with symptomatic carotid artery occlusion (CAO) has venous stasis retinopathy on ophthalmoscopy. Venous stasis retinopathy is associated with an impaired flow state of the brain.
