Dr. Diane N. Sayah is an optometrist with special interests in ocular biomechanics and hemodynamics. She obtained her Doctor of Optometry degree from the University of Montreal. She then completed her PhD in glaucoma and biomechanics research at the Maisonneuve-Rosemont Hospital (University of Montreal) and worked as a postdoctoral fellow at the Harvard Retinal Imaging Lab (Massachusetts Eye and Ear).

Dr. Sayah served as lecturer and clinical instructor at the University of Montreal School of Optometry for over seven years before joining the University of Houston College of Optometry as an Assistant Professor (tenure-track).

As a clinician-scientist, Dr. Sayah's interests are directed towards neurodegenerative diseases of the eye, particularly glaucoma, as well as myopia. Benefiting from cutting-edge technology and innovative methods for probing biomechanical and choroidal involvement in eye diseases, her objective is to lead translational research which will directly improve clinical care.
