1. Blood Clot in the Veins
The formation of blood clots that reduce or halt the flow of blood to the retinal veins is referred to as retinal vein occlusion. These blood clots can cause permanent damage to the eye and even blindness if left untreated. There are two types of these clots: If they occur in a large vein, it’s a central retinal vein occlusion (CRVO), while clots in smaller veins are branch retinal vein occlusions (BRVO).3‘Mending Vision in Patients with Eye Vein Clots.’ National Institutes of Health, U.S. Department of Health and Human Services, 22 Apr. 2016, www.nih.gov/news-events/nih-research-matters/mending-vision-patients-eye-vein-clots.
Laser therapy and injections can both be used to treat BRVOs, but there are currently limited options available for CRVOs. However, initial trials of injections show positive signs for CRVOs.
