Will my eye ever dilate again after vitrectomy :(
It the spot came, lasted minutes to an hour then went away it could be a TIA or transient ischemic attack due to disease of eye, brain, heart or blood vessels or it could also be an Eye Migraine which don't have headaches.
If the spot came and stayed it could be a blood clot in the eye or emboli to the eye or a tear in retina. you need to see an eye MD ophthalmologist in any case. Ask your family MD to refer you or find one near you at www.geteyesmart.org
