Research Program Overview

The faculty, Eye Clinic facilities, and Basic Science laboratories of the Department of Ophthalmology, Louisiana State University Health Shreveport, are dedicated to patient care, clinical and basic research. The research faculty of the Ophthalmology Department emphasizes the central role that evidence-based research plays in promoting knowledge-based medicine and good-medical practice. Current research efforts in the Ophthalmology sub-specialties areas are multi-focal, but all seek to understand the molecular mechanisms in ocular disease pathogenesis and the therapeutic potential and shortfalls of established and experimental treatments.
