I developed a sudden retinal detachment almost 3 years ago. Had surgery with a buckle , started to regain some vision, then a second detachment in same eye, 3 months later. A second buckle and vitroectomy(?) was done. Never regained vision in eye, instead have a grayish cloud . Last night, it felt like pressure inside eye, followed by pain, and watery eye. Several hours later, Eye is still painful and still feels like there is pressure. I am obviously concerned, but am unsure what might be causing this since I never regained vision. I also have a slight headache on that side of my temple. Any idea what may be going on now? What I can do to ease the pain and pressure feeling?
