Yeah, even plain retina exams cause me huge anxiety because of the magnifying glass thing they put on your eye, worse than having my dental root actually operated on for example. When I was very little (like a toddler) they did the retina exams at a hospital with a full anesthesia (thus weirdly one of my earliest memories is of the preperation for an anesthesia procedure), which was much more pleasant. Unfortunately they somehow expect adults to just deal with the exam and suck it up, and I can see why, but I draw the line at them actually messing with my eyeballs.
