The authors report on the occurrence of ocular abnormalities in X-linked ichthyosis (XLI) patients, in their carrier mothers and in healthy volunteers who served as controls. The diagnosis of XLI was based on: (1) demonstration of steroid sulfatase deficiency in cultured skin fibroblasts; (2) lack of hybridization of patient's deoxyribonucleic acid (DNA) with specific steroid sulfatase complementary DNA probe; (3) electrophoretic mobility of plasma lipoproteins. Cholesterol sulfate plasma levels were also determined. The incidence of corneal opacities was the same in XLI patients and in their carrier mothers (23.7 and 24.3%, respectively). Neither other corneal nor ophthalmological alterations were found. Moreover, in XLI patients the plasma levels of cholesterol sulfate were about twenty times higher than in controls. Our findings demonstrate that ocular changes do not seem to be an absolute criterion for a definite diagnosis of XLI and the fact that the pathogenesis of corneal opacities is not due to an accumulation of cholesterol sulfate, but rather that this compound probably induces physicochemical changes of the corneal tissue properties.
