Gonioscopy is a diagnostic test wherein the examiner looks at the trabecular meshwork and adjacent structures located in the angle of the anterior chamber of the eye, where the iris and the cornea meet.  This is done using a goniolens, a contact lens with a reflecting mirror or prism.  Most frequently performed at the slit lamp, the eye is numbed, the lens is placed on the cornea, and the goniolens mirrors facilitate a 360 degree view of the anterior chamber angle.

Indications for gonioscopy include, but are not limited to:  rubeosis, glaucoma, hypotony, occlusive disorders, diabetic retinopathy, aphakia, intraocular foreign body, and subluxated or dislocated lens.  Note that this list is neither exhaustive nor universally recognized.
