The bilateral occurrence of a malignant melanoma of the uveal tract is of sufficient rarity to warrant a short report. Schies-Gemuseus 1 has reported such a case as did Landsburg. 2 Carter 3 reported bilateral malignant melanomata of the irides. Similar cases were seen by Dixon 4 and Hirschberg. 5 However, in all these cases the tumor in the fellow eye was not proven histologically. The first proven bilateral case was that of Shine 6 in which the choroid and iris were involved respectively; Cordes and Cook 7 reported a similar case with histological proof. A. B. Reese, 8 in his book, mentions having seen one such case of bilateral melanomata of the uveal tract. In Landsburg's case, the melanomata occurred simultaneously. In Dixon's case, the interval was six months; in Hirschberg's case, one year; and in Shine's case, three years. Cordes and Cook's case was interesting in that, in
