Vascular Occlusion

Cause
Vascular occlusion is the blockage of the blood supply to the retina, the light sensitive membrane at the back of the eye. It happens when the small arteries or veins in the retina become blocked by plaque or fat deposits. Vision loss can occur. This may be the sign of other disorders such as glaucoma, hypertension, diabetes and other systemic disorders. There is risk of a stroke because the blockage that affects the veins and arteries in the eye, may also affect the brain. This condition is most common in elderly patients.
