Dr. Ervin’s research interests focus on the comparative effectiveness of interventions to treat and prevent ocular disease and visual impairment.  She is currently the Co-Principal Investigator of the Data Coordinating Center for a multicenter natural history study of Stargardt Disease with colleagues at the Wilmer Eye Institute. She was recently the Co-Principal investigator of a project funded by the Johns Hopkins Evidence-Based Practice Center and the Agency for Healthcare Research and Quality to prepare a comparative effectiveness review of screening methods and medical and surgical treatment for chronic open-angle glaucoma.  

Dr. Ervin has a long term interest in the design and conduct of randomized clinical trials and has worked on numerous studies of the causes, prevention, diagnosis or treatment of disorders of the eye and visual system including age-related macular degeneration, refractive error, low vision, cataract, and diabetic retinopathy.

Other research interests include the impact of US federal regulations for institutional review boards (IRBs) on ethical review of multicenter clinical trials and the advantages and disadvantages of alternate IRB review models for streamlining the review process in the multicenter setting.
