I also had an eye stroke in an already compromised eye ( myopic degenerative) my sight was gone for over a week. All the so called retina specialists said it would not come back . Gradually got some light and color back in the first month . Now four months later my vision has come back . Not like before, but it was already bad because of the eye disease. More grainy, still legally blind.Glasses don’t help at all. Sclera contacts have been a huge improvement as far as sight in both eyes, especially my bad eye. Don’t give up and don’t listen to negative diagnoses.
