The possibility of developing a sensitive test for the diagnosis of early glaucoma led to a series of studies of the light sense which were carried on at the Massachusetts Eye and Ear Infirmary under the direction of Dr. George S. Derby. In 1925, Waite, Derby and Kirk, in a preliminary report, showed that in established glaucoma the rate of dark adaptation is retarded and the ultimate threshold of sensitivity is not normal.¹ Moreover, in suspected glaucoma (cases of glaucoma affecting one eye) the eyes which were clinically normal showed alteration of the light sense, with retarded adaptation. The average curves suggested that the tests of the light sense might prove useful in diagnosis. Work was continued, using principally patients having glaucoma in one eye and the other eye normal, and in 1926, a second report by Waite. Derby and Kirk substantiated their first results.² Investigation of . . . [Full Text PDF of this Article]
