Jasdeep Sabharwal, M.D., Ph.D., is an assistant chief of service and assistant professor of ophthalmology at the Wilmer Eye Institute, Johns Hopkins Medicine location in East Baltimore and at Johns Hopkins Bayview Medical Center. He specializes in caring for routine and complex glaucoma using medical, laser, and surgical treatment, and also performs cataract surgery. 

Dr. Sabharwal completed his bachelor's degree in molecular and cell biology and neurobiology at the University of California, Berkeley, before earning his medical doctorate and Ph.D. in neuroscience at Baylor College of Medicine. He came to Wilmer to pursue his residency and glaucoma fellowship. 

His Ph.D. work focused on studying retinal ganglion cells, which are the cells that are lost in glaucoma. He identified early changes in cellular function prior to cell death. This work helped develop Dr. Sabharwal's interest in ophthalmology and focus on applying quantitative methods to studying eye disease.

Research & Publications

Research Summary

Dr. Sabharwal's research focuses on identifying the factors driving intraocular pressure fluctuations and determining the role of fluctuations in glaucoma worsening. This work can help determine which subset of patients need more frequent visits or early interventions for glaucoma. Newer devices to continuously monitor eye pressure or to provide sustained release of eye drops have significant promis, but significant research needs to be done before they can be used in routine clinical practice.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
