Ahh, the infamous "Topcon edema". Most likely a dirty lens. Dial in the minus diopter, then rack focus back all the way, then turn the viewing light up to full to visualize the culprit. ******** John C.

It appears to be increasingly worse. The reflection appears to be from the flash of the camera. Objective lens issue? Thoughts?
