MANY attempts have been made in the past to alter the usual technic of taking visual fields in an effort to detect the earliest changes due to glaucoma. Some have reduced the illumination (Bair,¹ 1940; Marlow,² 1947; Mann and Sharpley,³ 1947). Others (Derby, Waite and Kirk,⁴ 1926; Derby, Chandler and O'Brien,⁵ 1928) found that the light threshold and the dark adaptation rate are defective in early glaucoma. In all such tests perception involves visual acuity or form vision, and absolute light thresholds.

Since Phillips⁶ (1933) first reported on flicker fusion frequency fields, there has been increasing interest in this entirely different type of tests. Weekers⁷ (1947) has reported that flicker fusion frequency fields are depressed in cases of early glaucoma.

Unlike all other tests, determination of the flicker fusion frequency fields depends on two factors: (1) the length of the latent period between . . . [Full Text PDF of this Article]
