I lost majority of my vision in my right eye very suddenly. I spent 3 weeks going to eye doctors, neurologists, internists and no one had an answer as to what was happening. I just had a bunch of scary diagnoses thrown at me. I finally found this ophthalmologist on my own. Within a half hour appt, Dr D knew exactly what was happening. I finally had answers to what was going on and a very good prognosis. I wish I would have gone to him from the start. Would have saved a lot of money and anxiety.
