Glaucoma Care for Fontana Patients

You don't have to drive to Los Angeles for subspecialty glaucoma care. Inland Glaucoma Center is a quick drive west in Upland, where UCLA fellowship-trained, board-certified specialists diagnose and treat every type of glaucoma.

Dr. Robert Gunzenhauser and Dr. Marc Shomer, UCLA-trained glaucoma specialists serving Fontana

Glaucoma is the leading cause of irreversible blindness, and because it usually causes no symptoms until vision is already lost, the right specialist and the right technology matter. For Fontana residents, that expertise is close to home.

Our physicians completed subspecialty training at UCLA's Jules Stein Eye Institute and have collectively performed thousands of glaucoma surgeries and laser procedures. We manage everything from early ocular hypertension to complex and surgical glaucoma, using high-resolution OCT imaging, visual-field testing, and the full range of modern laser and minimally invasive options. Care is available in English and Spanish.
