Hello, Welcome to Just Answer
Are you available for chat now?
What you eye doctor has said is definitely true. One of the complications of branch retinal vein occlusion ( BRVO) is cystoid macular edema( CME). The treatment received so far is correct .
Is there any other treatment that would help?
Sorry, I meant "your" eye doctor.For treatment of CME grid laser is tried along with steroids. Injection Avastin helps to regress the vessels.Flurbiprofen eye drops are beneficial in early stages . I'm afraid that all possible methods of treatment have been tried already. The fact that the central vision is lost , it denotes that the macula, which is the central part of the retina contributing to 80% of our vision , is still having edema. These are refractory conditions which can take months to show improvement. I guess you need to wait some more time to see visible improvement. But as far as any other methods to be tried - well you have been given the best possible so far.
Thank you for answering my questions.
