Abstract

Familial lecithin: cholesterol acyltransferase (LCAT) deficiency is an inborn error of lipid metabolism clinically characterized by anemia, proteinuria, and corneal opacification. The authors review the literature dealing with 34 biochemically proven and 2 probable cases of LCAT deficiency, and describe the first case from a German-speaking country. Ocular findings were bilateral diffuse nebulous corneal opacification composed of innumerable minute grayish dots throughout the stroma. At the periphery of the cornea these dots increased, forming a ringlike band with indistinct margins. A small lipid deposit was also seen in the retina of the right eye. Vision was 20/20, but glare disability was significantly increased. Corneal opacification was also noticed in all cases of the literature. Anemia was detected at the time of diagnosis in 92% and proteinuria in 76% of the reviewed cases. Corneal opacification is the one absolutely obligatory clinical feature; moreover it is uniform and pathognomonic: a true indicating sign of LCAT deficiency.
