80 37 Color Atlas of Gonioscopy Corneal Edema When the cornea is too edematous to permit adequate visualization of the angle, topical glycerin can provide some clearing (81 and 82) . The eye should be topically anesthetized before using glycerin. Even with topical anesthesia glycerin can be uncomfortable. Corneal clearing is rapid. The exami nation shou ld be carried out quickly as the effects arc short- lived.

Some grading systems are quite simple - for example the ' wid e, intermediate, and narrow' classification of Go rin and Posner (1967). T he three primary alphanumeric systems that are cmrcntly used for grading the ang le a re those of Scheie, Shaffer, and Spaeth.
