Research Summary
Dr. Margeta specializes in glaucoma, which is a chronic blinding disease characterized by gradual loss of neurons that connect the eye to the brain. Elevated intraocular pressure remains the only modifiable risk factor for glaucoma; currently there no glaucoma treatments that directly confer neuronal protection or reverse existing visual field loss. Dr. Margeta’s research focuses on the role of neuroinflammation in the pathogenesis of glaucoma, with the goal of developing novel neuroprotective treatments for this progressive blinding disease.
Dr. Margeta was selected for the NIH/NEI-funded K12 Harvard Vision Clinical Scientist Training Program in 2016 and has received numerous other awards since then, including NIH K08 Mentored Clinical Scientist Research Career Development Award, Research to Prevent Blindness Career Development Award, and Alcon Research Institute Young Investigator Award. She is a member of the Glaucoma Research Foundation Catalyst for a Cure Initiative to Prevent and Cure Neurodegeneration.
