From these case reports it became apparent that dinitrophenol cataracts presented certain new and characteristic features:
(1) They occurred in young women who were physically normal save for varying degrees of obesity, and who were all in an age group in which senile cataract does not occur. [Note that there were three case reports in men] (2) The cataracts were bilateral, and appeared either during or following periods of "slimming" treatment with dinitrobodies. (3) An interval of months or years might elapse between the time the last dose was taken and the onset of blurred vision. (4) The lens changes were strikingly similar, and could be demonstrated by the biomicroscope at a time when vision for distance and reading was still normal. (5) After a gradual onset, the lens changes progressed with startling rapidity until vision was obscured.
(6) Treatment was without effect in staying their progress. (7) Surgical extraction of the lens was uniformly successful in restoring vision.
