With a PhD in neuroscience, Przemyslaw (Mike) Sapieha is the director of the Neurovascular Eye Disease Research Unit at Hôpital Maisonneuve-Rosemont. Using the eye as a model, his lab studies angiogenesis and the factors that control it. Specifically, he studies the cellular interactions and intracellular mechanisms that govern vascular growth in both physiological and pathological contexts.

The Canada Research Chair in Retinal Cell Biology and holder of the Wolfe Professorship in Translational Vision Research, Mike Sapieha is also an associate professor in the Department of Ophthalmology and an adjunct professor in the Department of Biochemistry and Molecular Medicine at Université de Montréal.

Neurovascular Eye Disease

Research interests

Vasoproliferative eye diseases are the main causes of vision loss in developed countries. For example, diabetic retinopathy and retinopathy of prematurity affects working-age and pediatric populations, while age-related macular degeneration affects older populations. These conditions are characterized by the excessive growth of retinal vessels that can lead to fibrotic scars and possibly retinal detachment. This disproportionate hyper-vascularization is part of a compensatory mechanism that attempts to overcome microvessel degeneration by restoring metabolic balance to the hypoxic retina.
