About Dr. Ahmara G. Ross

As an Assistant Professor of Ophthalmology and Neurology, I completed my ophthalmology residency at the University of Pittsburgh then fellowships in Neuro-ophthalmology and Glaucoma at the Scheie Eye Institute, University of Pennsylvania. I also has a PhD from Thomas Jefferson University. In addition to caring for patients with both glaucoma and neuro-ophthalmologic disorders, she also performs ocular surgery ranging from cataracts, minimally invasive, and incisional glaucoma surgery.

My career path has put me in a unique position to diagnose, treat, and manage optic neuropathies beyond the spectrum of glaucoma, but to view this disease as another neuro-degerative disease in need for sight changing therapy.  My interest and professional strengths go beyond basic science research with my clinical approach also aimed at addressing socio-economic barriers to the treatment of healthcare.

I joined the faculty in 2017 and my research is currently funded by an NIH K08 Career Development award to investigate the neuroprotective potential of gene therapy directed at retinal ganglion cells and neighboring support cells to treat chronic glaucoma.  She is also collaborating on similar research using gene therapy to treat other mouse models of optic neuropathy such as trauma, compression, and inflammatory..

Patient Satisfaction Ratings

Patient Rating Breakdown

The Patient Satisfaction Rating is an average of all responses to the care provider related questions shown below from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.

Responses are measured on a scale of 1 to 5 with 5 being the best score.
