Hi @ozziero,
Huh, what you've described sounds strange. I am at increased risk for retinal detachment (and unfortunately you are, as well, since I see you have AMD) and I can't see what you're seeing but what you've described sounds like an emergency symptom I've been warned about. I have a bunch of floaters and they're harmless, but suddenly having a group of a lot of new ones clustered like that or a sudden large new one would be a sign of possible trouble. Routine eye exams can't catch detachment but since you saw a retina specialist I'd assume he ran all tests needed to rule it out? I and someone I know have dry eye but I've never heard of it causing something like that. If it were me I would get a second opinion.
