Temporary, Partial Vision Loss

Content: Like migraine, this condition can cause temporary vision loss. Treatment can fully restore your sight. When a blood vessel in your retina tightens, it causes a vasospasm. This cuts down on blood flow, which can bring on temporary vision loss in one eye. Various conditions can lead to a vasospasm. These include a retinal migraine, atherosclerosis, and high blood pressure. If you have a retinal vasospasm, your doctor may recommend aspirin or a type of medicine called a calcium-channel blocker to relieve it. You’ll also work with your doctor to manage whatever caused the retinal vasospasm in the first place. Closed-angle glaucoma: When your eye’s iris bulges, it can prevent fluid from draining properly.
