The Gonioscope GS-1 is an ophthalmic camera with gonioscopic prism that is intended to capture, display and store images of the anterior chamber angle and its peripheral part. This study evaluates the efficiency of Gonioscope GS-1 in glaucoma patients.With the captured images, the glaucoma diagnosis and post-operative observation are enabled.

• Typical glaucomatous field loss in reliable VF, reproducible glaucoma hemifield tests labeled outside normal limits on at least two consecutive tests.
• Both eyes will be included, except in cases where only one eye meets study criteria

Exclusion Criteria:

• Corneal opacities (scars, edema, etc.)
• Pregnant or planning to become pregnant
