Dr. Razek G. Coussa is a vitreoretinal surgeon with broad expertise spanning adult and pediatric retina, inherited retinal diseases, and complex vitreoretinal surgery. Before joining Retina & Vitreous Consultants of Wisconsin, he served as a clinical assistant professor and adult/pediatric vitreoretinal surgeon at the Dean McGee Eye Institute, where he founded a retinal gene therapy center and performed FDA-approved subretinal gene therapy. He now provides comprehensive care for conditions such as macular degeneration, diabetic retinopathy, retinal detachment, and traumatic retinal injuries, while building pediatric and inherited retinal disease programs for patients across Wisconsin. Dr. Coussa completed ophthalmology residency at McGill University and pursued four years of advanced fellowships: Pediatric Ophthalmology and Inherited Retinal Diseases at the Cole Eye Institute (Cleveland Clinic), Medical Retina and Molecular Ophthalmology at the University of Iowa, and Vitreoretinal Diseases and Surgery at the University of Iowa.
