A previous report by us1has detailed the occurrence of posterior subcapsular cataracts (PSC) in 5 of 22 (23%) rheumatoid arthritis patients treated with 10-16 mg. of prednisone or its equivalent daily for one year or more and in 12 of 16 (75%) treated with 16 mg. or more. The age of the patients and the duration and severity of rheumatoid arthritis showed no significant correlation with the development of cataracts, and since no cataract of this type was seen in 19 rheumatoid arthritis patients who were not treated with corticosteroids, it was suggested that corticosteroids were the chief etiological factor. It is the purpose of this paper to delineate and discuss the cataracts of the above 17 patients from an ophthalmologic orientation. Material and Methods The population was composed of 5 females and 12 males, ranging in age from 34 to 61 years.
