Glaucoma is a disease of the optic nerve that can cause blindness if left untreated. There are no symptoms in the early stages of the disease. We have a glaucoma clinic quarterly using an optical coherence tomographer (OCT), which measures retinal nerve fiber layer thickness. In glaucoma the nerve fiber layer thins before a visual defect occurs. So we can now diagnose glaucoma earlier than before and thereby start treatment earlier to help prevent blindness.
