The Department of Ophthalmology at UMMS is committed to advancing the field of ophthalmology through basic and clinical research, translation of advances from the laboratory to clinical practice, and the training of medical students. Among other areas, we conduct basic and translational research to develop therapies for retinal disorders.
Our basic research program in our state-of-the-art research laboratories focuses on understanding the biochemical basis of retinal and macular degeneration, small molecule drug discovery, and the molecular and cellular fate of misfolded proteins associated with retinal diseases. Read more at the Khanna Lab, and the Punzo Lab.
Our faculty and staff are leaders in gene therapy and biochemical research contributing to clinical and translational research efforts. We conduct clinical trials, clinical research, and novel drug testing, which has led to the creation of two biotech startup companies.
Through our UMass Memorial Eye Center, we provide comprehensive ophthalmology services to patients. We specialize in vitreoretinal diseases such as diabetic retinopathy, glaucoma, and age-related macular degeneration. We also provide patient care in orbit/oculoplastics, neuro-ophthalmology, and uveitis. Our services include the latest technologies for imaging, perimetry, and electrophysiology.

We have developed a member-supported network for information-sharing among physicians, researchers, and others that focuses on the latest developments in vision-related research and clinical findings.
