If one had PRP Laser for PDR and a clearing Hemorrhage and one and a half weeks later one sees a BIG WHITE ROUND CIRLE in the visual field for about 5 seconds and this may take place 4 or 5 times a day over past few days, what can this signifiy other than a doctor saying it's just from the laser? And when will it clear, what can be done if anything? Thank you for a speedy reply please. Perhaps Dr. Doreen Fazio, Ophthalmologist can respond or another. It will be appreciated!!! The big white circle is frightening to see. Thx.
