- 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 opacity.
- Ophthalmic appearance.
- Lipid deposition may be:
- Associated with another ocular surface pathology - lipid keratopathy.
- Associated with circulating lipid abnormalities - arcus lipoides corneae.
- In most cases, lipid deposition is not severe enough to compromise vision and thus prognosis for long-standing ocular health is good.
Reasons for treatment failure
- In some cases lipid deposition does compromise vision. Here full thickness keratopathy may be useful although this is rarely available.
