In a preliminary communication Hobbs and Calnan (1958) report the cases of 30 patients under treatment with "Chloroquine". Three of these patients only expertenced spontaneous perception of haloes. Nineteen complained of visual upset, and of these 19 patients the corneee were normal in four. In the nine patients who had no symptoms, all had changes in the corneal epithelium. The corneee in these cases had a similar appearance to those described by Calkins (1958), but with some changes in the stroma beneath Bowman's membrane in a few cases. Hobbs and Calnan were able to conclude from their findings that a complaint of visual disturbance is an unreliable guide to the presence of corneal changes. The ocular symptoms were uniform in all the cases reported-blurred or misty vision, difficulty in driving a motor-car. In practically all cases visual acuity indoors as tested with Snellen type was normal, but vision was particularly affected at night, and those who drove a car had great difficulty.
