Gonioscopy
Gonioscopy is an examination used to evaluate the drainage system of the eye, or the trabecular meshwork, and its anatomical relation to the adjacent iris. A special contact lens mirror is used to visualize these structures, which are hidden from direct observation. Gonioscopy is a painless examination used to determine whether the area where fluid drains out of your eye, or drainage angle, is either open or closed. Depending on your age and whether you are at high risk for developing glaucoma, gonioscopy may be a routine part of your evaluation.
