Understand Your Glaucoma Diagnosis

The diagnosis of glaucoma is made when your eye doctor notices a particular type of damage in the optic nerve known as cupping. This diagnostic finding can occur with or without high intraocular pressure.

Optic Nerve Cupping

Both people with and without optic nerve damage have optic nerve cupping, although those with glaucoma tend to have a greater cup-to-disc ratio. A cup to disc ratio greater than six-tenths is generally considered to be suspicious for glaucoma.
