What is crystalline Keratopathy?

Crystalline keratopathy is a condition in which crystals are deposited in the corneal epithelium and/or anterior stroma. Affected individuals frequently present to the ophthalmologist with symptoms of pain, decreased vision or photophobia.

What causes crystalline Keratopathy?

ICK occurs more commonly in corneal grafts or otherwise immunocompromised corneas. The most common risk factors for infectious crystalline keratopathy include history of penetrating keratoplasy (usually many months after transplant), corticosteroid use, and contact lens wear.

What causes tears to crystalize?

But when your eyes are closed and your eyelids are not blinking, dirt and debris within the eye isn’t continually washed over by tears, which would help to dilute them. So at night, dryness causes the stuff in tears to precipitate out, explains Chen.

What is the pathophysiology of band keratopathy?

The pathology for band keratopathy occurs from the calcium deposition (in hydroxyapatite form) into the bowman’s layer, epithelial basement membrane and the anterior stroma.

What are the characteristics of climate droplet keratopathy that distinguish it from band?

Characteristics of climate droplet keratopathy that distinguish it from band keratopathy is its occurrence in endemic regions with more globular deposits. Urate keratopathy is unique as it has brown deposits. Diagnosis of band keratopathy is primarily based on history and slit lamp examination.

Can multiple myeloma cause crystalline keratopathy?

Monoclonal gammopathy and multiple myeloma have been reported as rare causes of crystalline keratopathy, 6 and the ophthalmologist should entertain the possibility of a lymphoproliferative disorder in a patient who does not fit the clinical pattern of other causes of crystalline keratopathy.
