69-year-old man has diabetic retinopathy in both eyes. His vision is doing pretty well. Recently he is noticing that he can see pretty well without his glasses. When I have been watching the last few visits, there is a patch of edema in the right eye, which looks to be possibly worsening. I saw him last four months ago. VISUAL ACUITY: (without correction): OD: 20/25, OS: 20/50. IOP: OD: 16, OS: 14. There is 1+ nuclear sclerosis in both eyes. EXTENDED OPHTHALMOSCOPY: OD: C/D ratio is 0.4. There are patchy microaneurysms. There is light laser. There is edema superotemporal to the fovea within 500 microns of the center. OS: Vertical C/D ratio is 0.4. There are patchy microaneurysms. There is light laser. There is no edema or proliferation. The OCT scan of the right eye does show parafoveal edema touching the center. The left eye has actually increased foveal thickness. A fluorescein angiogram shows multiple microaneurysms in both eyes with leakage from a cluster superotemporal to the fovea in the right eye . IMPRESSION: 1. BACKGROUND DIABETIC RETINOPATHY IN BOTH EYES. 2. CLINICALLY SIGNIFICANT MACULAR EDEMA IN THE RIGHT EYE. 3. FOVEAL EDEMA IN THE LEFT EYE. 4. STATUS POST MACULAR LASER IN BOTH EYES. DISCUSSION: I explained to the patient that the right eye does have diabetic retinopathy threatening central vision and that with laser treatment we could reduce the risk of vision loss. I treated the right eye without any difficulty.
