question: Hello doctor,  The question I have is concerning the retina photographs that I have attached to this question. From those can you tell if I suffer from a condition known as "disc at risk" or "crowded optical disc"? I understand that it is possible for people with this condition to suffer from non-arteritic anterior ischemic optic neuropathy (NAION) when also taking ED medication. I have had an eye test done but the person who did the test could see no problem with my eyes but seemed unaware of crowded disc or NAION. I am 60 years old, not taking any medication and no previous history of eye problems or NAION.
