Hi, I am a 25 year old with a retinal hemorrhage/macular pucker/Coat's Disease variant in my right eye. My vision has been getting worse and gone to 20/80. I am being treated with Avastin injections and awaiting a vitrectomy. However, I am worried about cataracts forming after the vitrectomy. So I want to make sure that a vitrectomy is the usual treatment recommended for my condition.
