ESTIMATION OF WIDTH OF ANGLE OF ANTERIOR CHAMBER - INCIDENCE AND SIGNIFICANCE OF NARROW ANGLE

Evaluation of the anterior chamber angle width by flashlight and by slitlamp correlates well with gonioscopic classification of the angle. There are substantial clinical advantages to making this evaluation a routine part of every eye examination; it particularly alerts the clinician to the possibility of angle closure in the narrow-angle group and helps avoid gonioscopic misinterpretations. Narrowing of the anterior chamber angle progresses during aging but Grade-1 angles are found in only 0.64% of an aging population and Grade-2 angles in only 1%. Hyperopia is more often associated with a narrow angle than is myopia; myopia is seldom associated with a narrow angle. © 1969.
