Lipid corneal dystrophy

Contributor(s): David L Williams

Introduction

  • Cause: lipid deposition in the cornea may occur:
    • As a primary problem related to lipid handling by keratocytes.
    • As a problem secondary to a circulating lipid disorder.
    • As a problem secondary to pre-existing corneal pathology.
  • Signs: corneal opacity.
  • Diagnosis: ophthalmology/slit lamp biomicroscopy.
  • Treatment: dietary manipulation to reduce the speed of lesion progression. Superficial keratectomy to remove lipid deposits in severe cases.
  • Lipid deposition in the cornea may be classed as:
    • Corneal lipid dystrophy Lipid keratopathy Rough Collie male 3 years (bilateral inherited disease with no predisposing systemic or local cause).
    • Lipid keratopathy Lipid keratopathy Pug 13 months (lipid deposition in site of pre-existing corneal pathology, especially vascularization).
    • Corneal arcus deposition next to a limbal mass.
    • Arcus lipoides corneae with systemic elevated plasma lipid.
