Are other techniques used during Vitrectomy procedures?
Yes, scar tissue referred to as epiretinal membranes can be removed from the retinal surface using various methods of membrane peeling. Scar tissue can be removed from underneath the retina (subretinal surgery). A portion of the retina can be intentionally resected (cut) if it is contracted too much to become reattached. This is called retinectomy. Laser or cryo (freezing) treatment is usually used to make an intentional scar to seal retinal holes, breaks, and tears. This effect takes 7-10 days to be effective in preventing fluid from flowing through the retinal defect. Most laser or cryo applications are in the non-seeing far peripheral retina and do not cause significant loss of peripheral vision.
