What is Gonioscopy? - Glaucoma Glossary

Gonioscopy is a biomicroscopic examination utilizing a specialized mirrored contact lens to visualize the anterior chamber angle anatomy, specifically the trabecular meshwork.

What it means for the patient

This is the test where the eye doctor briefly places a tiny contact lens on your numbed eye. They use mirrors inside the lens to look around the tight corners of your inner eye, ensuring the structural drain is physically open, not blocked by your iris.

Clinical significance

It is the definitive clinical modality for differentiating open-angle from angle-closure glaucoma variants and identifying secondary pathologies like pigment dispersion or neovascularization in the angle.

How it is tracked

Findings from gonioscopy heavily define the diagnosis taxonomy mapping required for patient configuration in the clinical timeline.
