To the Editor.—Perusing the minutes of the December 1933 session of the Section of Medicine and Ophthalmology of the New York Academy of Medicine (Arch. Ophth.12:143 [July] 1934), which meeting I was unable to attend, I noted that in the papers read by Dr. Waite, of Boston, and Dr. Wilder, of Rochester, Minn., and in the discussion following these papers, an interesting and apparently not so rare diabetic condition of the iris was overlooked. I allude to rubeosis iridis diabetica, first described by Robert Salus in 1928 (Med. Klin.24: 256, 1928).
Salus gives an account of three cases in men of 56, 64 and 75 years of age, respectively, seen by him within five years ; all had diabetes of moderate severity dating back many years, and all used insulin regularly. One showed little sugar, the other 4.5 per cent and the third 4 per cent. In
