Diabetic Retinopathy (DR) is a complication of diabetes associated with irreversible loss of blindness. Various types of DR have been reported like mild non-proliferative retinopathy, moderate non-proliferative retinopathy, severe non-proliferative retinopathy and proliferative retinopathy. A number of signaling mechanisms like nuclear factor kappa-B (NF-κB), cyclo-oxygenase (COX), intracellula...

BACKGROUND This retrospective study was conducted to analyze the progression rates of diabetic retinopathy (DR) after phacoemulsification in diabetic patients and to determine whether phacoemulsification causes the progression of DR. METHODS The medical charts of diabetic patients who had undergone cataract surgery using phacoemulsification techniques during a 3-year period and had completed ...
