Overview

​

Retinal vein occlusions occur often as a complication of long-standing hypertension.  

 

These occlusions may occur in a limited part of the retina (branch retinal vein occlusions, hemiretinal vein occlusions), or they may affect the entire retina (central retinal vein occlusions).

 

The diagnosis of retinal vein occlusions requires testing in the clinic and a complete dilated examination.  The intraocular pressure, iris, and retina must be checked for abnormalities. 

 

A variety of treatment options exist for macular edema associated with vein occlusions.  These may include intravitreal injections or laser in selected cases. 

 

To avoid complications from the disease, such as neovascularization of the retina or iris, patients should have a retinal examination and be treated in a timely manner.
