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.
