If Wills Eye Hospital found nothing wrong, then there is nothing wrong. Wills is one of the leading eye hospitals in the country. If your brother has not lost any significant vision and he is fifty, then the only thing he needs to worry about is macular degeneration as an aging disease. I have worked in retina for eight years and it sounds like his eye problems are in brain.

Is it possible that your brother has the same condition as your son?

Again this is a very common symptom with that condition.

Sounds like some sort of delusion... If the eye hospital says there is nothing wrong then there is most likely nothing wrong. Perhaps get a second opinion to make him feel better. If that doesn't work, try suggesting a pycologist..
