Summary

This study compares three commonly used instruments for scleral depression, a routine eye exam technique that presses on the eye to view the retina. The goal is to see which tool causes the least pain and is easiest for doctors to use. Adults with symptoms of posterior vitreous detachment will have each eye examined with a different instrument and rate their discomfort.
