In part 1 of this Exclusive Interview, Dr. Paul Chous discusses the significance of studies around the three anti-VEGF injections that seek to determine which is the best.

New ultra-wide-field technology gives ophthalmologists opportunity to view 80% of retina...

Screenings for diabetic retinopathy should begin at age 15 or 5 years after diagnosis....

Researchers study retinopathy as possible indicator of nephropathy… The number of diabetes mellitus cases is on the rise while the incidence of end-stage kidney disease from diabetes has decreased over the years. However, diabetes remains the main cause of end-stage kidney disease in the United States and other countries. There …

The difference between low and high ankle-brachial index can be indicator for diabetic retinopathy… Patients with diabetes are at a greater risk for peripheral artery disease caused by atherosclerosis. Previous studies showed that many diabetic patients who received an amputation had peripheral artery disease. The ankle-brachial index is used as …

Protection of visual function may signal disruption of mechanisms underlying diabetic retinopathy (DR)… This was a 6-month randomized, controlled clinical trial of patients with type 1 and type 2 diabetes with no retinopathy or mild to moderate non-proliferative retinopathy assigned to twice-daily consumption of placebo or a novel, multi-component formula …

Patients taking metformin during a 10-year study had a 25% reduced risk of developing glaucoma… The researchers hypothesized that a drug that mimics caloric restriction, such as metformin, might reduce the risk of glaucoma, said Julia Richards, lead researcher and ophthalmology professor at the University of Michigan Ann Arbor.

Pre-proliferative changes are characterized by the following. Multiple (> 5) cotton-wool spots. Multiple large blot hemorrhages. Venous abnormalities: irregularities, beading, looping or reduplication. Intraretinal microvascular abnormalities: …

David Levy, MD, FRCP      Non-proliferative diabetic retinopathy Background retinopathy Microaneurysms Small, red, intraretinal lesions usually found at the posterior pole of the eye, around the disc and macula. They occur in areas of capillary non-perfusion and show leakage of fluorescein. It is worthwhile estimating the number of microaneurysms as it has …
