: William P Beetham had a surprising idea he and his colleagues at Joslin Diabetes Center’s Beetham eye clinic including son-in-law Lloyd M Aiello had noticed that eyes with previous retinal scarring rarely got proliferative diabetic retinopathy what if they thought we scar the retina on purpose with a laser and so back in those days about 40-to50 percent the patients could go blind from diabetic eye disease the advent of the laser changed that dramatically so the pan retinal laser photocoagulation was developed by Dr. beef him and dr. Hillel working together here at the Joslin and that uses a laser beam a very highly focused beam of light that shines into the back of the eye and actually causes little scars very very small scars in many areas of retina this radical treatment was originally met with angry resistance in the eye care community some going as far as calling it malpractice but the undeniably positive results soon put an end to the controversy often with as few as one two three laser treatments over % of severe vision loss could be prevented this Jocelyn pioneered treatment became the standard of care for diabetic retinopathy for more than years but the treatment was not without drawbacks we were actually destroying areas of retina to save the center part of the retina where most of the vision is were your sharp petition hits and so there were some side-effects that went along with that the side effects included attacked was more difficult to see at night it was more difficult to see in your peripheral vision out to this side and it was very difficult going from aright room into a dark room things like that but that was part of the treatment we couldn't get around that but that was a very good trade-off to keep her center vision and remain functioning while laser helped preserve the vision of people with diabetic retinopathy for decades researchers were on the hunt for something more something that could improve vision
