Myotonic dystrophy: pathological study of the eyes.

A 56-year-old patient with histopathologically established myotonic dystrophy is described. Gross pathological examination of the eyes revealed cataracts and peripheral retinal dystrophy as described previously. Lacy vacuolization of the pigment epithelium of the iris and vacuolization of the nonpigmentary ciliary epithelium were also found. These latter findings have, to our knowledge, not been hereto described in the literature.
