Band keratopathy

Calcific band keratopathy (BK) results from calcium hydroxyapetite deposition in the superficial cornea, mainly Bowman layer. It can be caused by chronic ocular inflammation, hypercalcemia, hyperphosphatemia, chronic exposure to mercurial vapors or preservatives, silicone oil, primary hereditary transmission. It is often idiopathic. BK usually begins as fine, yellow-white deposits in the periphery that may coalesce over time to form a horizontal band across the cornea.
