Occlusions are the result of a blockage in the veins. This is usually because of a blood clot restricting the blood flow. Exact causes are unknown, but there are a few conditions which make the chance of developing a retinal vein occlusion more likely.
- High blood pressure
- High cholesterol levels
- Some rare blood disorders
The treatment for a retinal vein occlusion depends on the type of occlusion and the severity. Some commonly used treatments include:
- Laser treatment
- Drug injections
- Vitrectomy – a type of eye surgery which addresses issues in the vitreous or the retina.
A branch occlusion may not require treatment and the condition may resolve itself with time, a central retinal vein occlusion, on the other hand, requires immediate treatment.
If you think you might be experiencing any of the symptoms of a retinal vein occlusion please see an eye doctor immediately.
