Flashes floater veil. Vitreous separation ; traction on the retina causes retinal tears-causing vitreous floaters ; hazy vision. Laser helps to prevent the tear from progressing to a retinal detachment as fluid flows though untreated tears and the retina falls off the back of your eye-like wallpaper coming off a wall. This causes a veil in your side vision then central vision loss. It is painless.
Causes. Rhegmatogenous retinal detachments(rd) are caused by a tear in the retina. Serous rd's are caused by fluid leakage under the retina. The rd is repaired by doing a pneumatic retinopexy, a vitrectomy a scleral buckle or a combination of the three. The healing depends on which procedure is performed. The return of vision depends on the length of the detachment prior to repair but may take 6 -12m. Read more...
