Does the Optic Disc Grading Done Visually by Your Doctor Agree With Optic Nerve Testing Which is Done by Machines?

Completed

Conditions studied: Open Angle Glaucoma

In brief

The purpose of this study is to determine how well the DDLS (Disc Damage Likelihood Scale) (which is a method used by the eye doctor to evaluate how healthy the optic nerve is) measures up to the standard glaucoma tests: OCT (Optical Coherence Tomography), the HRT (Heidelberg Retinal Tomography) and the HVF (Humphrey Visual Field).
