I had surgery to repair a macular hole 2 days ago. Have kept my face down til last night. turned over and slept on my back probably for 6 hours (this was night 2 post surgery). Did I do irreparable damage? Today I see a black outline around the outside of my eyeball.is this normal. My vision was20/25 before surgery. I am not diabetic andin good health, age 51 female. Will staying down 6 more days help?
