A third-generation ophthalmologist, Dr. Aiello is committed to eliminating visual loss resulting from diabetic retinopathy (a condition in which abnormal blood vessels grow on the retina) and other related retinopathies which account for the majority of blindness among working-age individuals in America and other developed countries. These conditions are usually caused by insufficient blood perfusion with subsequent proliferation of sight-damaging blood vessels and abnormal vessel leakage in the retina. Dr. Aiello's research aims to determine the biochemistry and molecular mechanisms underlying early diabetic retinopathy and other retinal vascular disorders, and then develop and test novel therapeutic interventions through rigorous translational and clinical trial research.

Dr. Aiello directs the clinical alliance between Massachusetts Eye and Ear and the Beetham Eye Institute. Dr. Aiello is also chairperson of the Diabetic Retinopathy Clinical Research Network.
