Pathologic Optic Disc Cupping

Optic disc cupping

In this eye, the disc neuroretinal rim is much thinner than in the normal optic disc. The cup-to-disc ratio here is about 0.8—much greater than the physiologic limit of 0.5! When the cup-to-disc ratio exceeds 0.5, optic disc cupping is probably pathologic. This patient has glaucoma. To find out more about glaucoma, click here.
