A Novel Symptomatic Lecithin-Cholesterol Acyltransferase Gene Mutation With Corneal Amyloidosis.

LCAT deficiency is a rare genetic disorder that can cause corneal opacities because of lipid deposition in the cornea. Systemic manifestations may help in the differential diagnosis to other diseases associated with severe high-density lipoprotein cholesterol reduction. Genetic analysis is employed to confirm the diagnosis. Some mutations in the LCAT gene seem to be associated with secondary corneal amyloidosis. Further investigation of this association is warranted. A recurrence of corneal opacity after PKP seems to occur mainly in the anterior corneal stroma.
