Central Retinal Vein Occlusion (CRVO) Treatment
The blocked vein in CRVO cannot be unblocked. The main goal of treatment is to keep your vision stable. This is usually done by sealing off any leaking blood vessels in the retina. This helps prevent further swelling of the macula.
Your ophthalmologist may treat your CRVO with medication injections in the eye called “anti-VEGF injections.” The medicine can help reduce the swelling of the macula. Sometimes steroid medicine may be injected in the eye to help treat the swelling.
If your CRVO is very severe, your ophthalmologist may do a form of laser surgery. This is called panretinal photocoagulation (PRP). A laser is used to make tiny burns to areas of the retina. This helps lower the chance of bleeding in the eye and keeps eye pressure from rising too much.
It usually takes a few months after treatment before you notice your vision improving. While most people see some improvement in their vision, some people won’t have any improvement.
