i had retina detachment surgery in 97, then laser because of thinning of retina in other eye and then once laser on eye which had RD surgery, i always had some flashers in other eye (good eye) i got or 6 months regular checkup. i was advised not to do running, heads down yoga or too much jumping, not to pick heavy weights...not sure what exercise is good for me...also i spent long hours in front of laptop due to my work..not sure if that can cause any trouble
