gonioscope

An optical device consisting of a thick contact lens incorporating an angled mirror that allows examination of the otherwise visibly inaccessible angle between the back of the CORNEA and the front of the IRIS. This angle is important as the site of drainage of the aqueous humour from the eye, and may be blocked in some forms of GLAUCOMA.

gonioscope

Instrument used to observe the angle of the anterior chamber of the eye, usually consisting of a biomicroscope in conjunction with a prismatic contact lens (e.g. Allen-Thorpe gonioprism) or a contact lens and mirror (e.g. Goldmann lens). It facilitates the diagnosis of angle-closure and open-angle glaucoma, as well as the diagnosis of secondary glaucoma (Fig. G5). See gonioscopic lens; Koeppe lens.
