Abstract
VALDEZ-PAYAN, Edna L. et al. Schnyder crystalline dystrophy. Rev. mex. oftalmol [online]. 2022, vol.96, n.6, pp.259-262. Epub Apr 10, 2023. ISSN 2604-1227. https://doi.org/10.24875/rmo.m22000245.
Introduction:
Schnyder's crystalline dystrophy is a rare autosomal dominant disease. This disorder causes a stromal dystrophy, characterized by bilateral corneal opacification, resulting from an abnormal accumulation of cholesterol and lipid. UBIAD1 is the causative gene.
Case report:
A male patient aged 49 with a history of progressive visual deterioration since adolescence, hypercholesterolemia and cholecystectomy. On examination it was found both eyes with discoid heterogeneous corneal reticular opacity yellowish-white of well-defined edges with the presence of fine crystals polychromatic and a small area surrounding clear cornea and a lipid arc 360°; the perilimbic area was respected.
Keywords : Cholesterol; Lipids; Corneal dystrophy; Schnyder corneal dystrophy; Schnyder crystalline corneal dystrophy.
