I had a complete detachment of retina 2years and 9months ago they used surgery and gas bubble . The retina detached again as soon as bubble dissipated, in weeks. Second surgery they put buckle and oil in . I have a lot of scarring in middle of eye so vision is poor. I have now had oil in for almost 3 years. I just wonder what signs and symptoms i should be looking for if oil fails, or it i should worry about long term issues with oil.
