Can pigmentary keratitis be cured?
In most cases, pigmentary keratitis cannot be fully reversed. The pigment may lighten over time, but it is uncommon for the pigmented deposits on the cornea to fully resolve. In cases of KCS, however, restoring an appropriate tear film may allow the discolorations to completely resolve.

What is lipid Keratopathy?
Lipid keratopathy is a disease in which fat deposits accumulate in the cornea, leading to opacification and decrease of visual acuity. This condition can be idiopathic without signs of previous corneal disease or secondary to ocular or systemic diseases.
Does pigmentary keratitis always cause blindness?
Pigmentary keratitis is a term used to describe the development of corneal pigmentation associated with chronic inflammation [1]. If PK encroaches upon the visual axis, it can cause significant visual impairment and, in severe cases, blindness [2, 3].
Is pigmentary keratitis painful?

What causes pigmentary keratitis?
The cause of pigmentary keratopathy is multifactorial. Corneal irritation from abnormally placed lashes, medial entropion (eyelids rolling in), and nasal fold trichiasis are common. Decreased production of tears (“dry eye”) and/or premature evaporation of tears is almost always present.

What causes corneal lipidosis?
What causes corneal lipidosis? There are three main causes of corneal lipidosis: corneal dystrophy, corneal degeneration, and elevated blood cholesterol levels. Corneal dystrophy is an inherited, or genetic condition and is most commonly seen in dogs.
How do you treat fat deposits under eyes?
Treatment for cholesterol deposits around your eyes
- Surgical excision using a very small blade is typically the first option to remove one of these growths.
