I saw the opthamologist today who confirmed the k sicca and discussed possible punctual plugs. We talked in depth about my night blindness symptoms and I told him that the optometrist in Alabama said that the black spot was a nevus. He looked at it and then dilated my eyes and He did a different exam where he put a magnifying glass there and put a REALLY bright light in my eye and then said he wanted to do an ultrasound. He said that it was not a nevus but actually a pigmented change on the retina. He said I need to have yearly checkups to monitor it and explained to me the symptoms of a retinal detachment and told me I would need to go to the ER if I had them. He also said if I have an increase in floaters to go back and see him before my follow up. I have a follow up in two months to check on the dry eyes since they were really dry at this appointment. Can anyone help explain this a bit more in detail to me and in a way that I can understand it better?
