Retinal Vein Occlusion
What is a Retinal Vein Occlusion?
This is the blockage of vessels that drain blood from the eye causing damage to the retina. There are different types which can define the severity of your symptoms. This can be caused from the hardening of blood vessels or a blood clot.
Risk of RVO
Risk factors include having diabetes, hypertension, glaucoma (abnormal eye pressure) and atherosclerosis (hardening of blood vessels).
Symptoms of RVO
Symptoms include blurred or decreased vision, floaters and pain.
Detection of RVO
- A complete dilated eye exam, which includes viewing the retina with special magnification
- Optical Coherence Tomography (OCT): A non-invasive and painless imaging technique that captures images of the macula at microscopic levels
- Fluorescein Angiography (FA): A vegetable based dye is injected into the arm and produces images of the retinal circulation to identify areas of blockage.
Treatment of RVO
There is no cure for RVO. Observation is sometimes employed as fluid and hemorrhages can sometimes subside on its own. Some treatments that may help include:
- Laser therapy
- Intraocular injections
