The purpose of this study was:(1) to de termine the accuracy of methods for evaluat ing the angle of the anterior chamber width without resorting to gonioscopy and (2) to determine the incidence of narrow angles in a normal population. The reliability of esti mating angle width by use of flashlight in spection or slitlamp biomicroscopy has not previously been checked in any large series of patients. We evaluated over 5,000 patients seen for refraction. Four hundred eyes were examined by gonioscopy to determine the correlation with the estimated angle width. All narrow-angle eyes were gonioscoped. The clinician who fails to note a narrowed angle is missing a fundamental physical find ing of vital prognostic importance to the pa tient; if mydriatics are used, for example, there is the risk of precipitating an angleclosure glaucoma with all its attendant physi cal and legal implications.Gonioscopy is required in the classifica tion of glaucoma. In the routine examination of nonglaucomatous patients it is impractical to perform gonioscopy; it is done only if the angles are thought to be narrowed. The oph thalmologist must know whether or not the angle is capable of occlusion; this permits him to make such objective judgments as: 1. Deciding on the safety of mydriasis in routine office examinations, prior to such surgery as cataract extraction, or its thera peutic use in such conditions as corneal ul cers or uveitis.
