Band keratopathy
Band keratopathy is a corneal disease derived from the appearance of calcium on the central cornea.

It is an example of metastatic calcification that occurs in the presence of hypercalcemia.

This is an example of metastatic calcification , which by definition, occurs in the presence of hypercalcemia
-
Calcification occurs in the epithelial basement membrane, Bowman's layer, and anterior stroma with destruction of Bowman's layer.

Band keratopathy is seen when there is calcification of the epithelial basement membrane , Bowman's layer , and the anterior stroma with destruction of Bowman's layer

Calcium salts are intracellular when due to systemic calcium metabolism alteration, and extracellular when due to local disease.

The calcium salts are intracellular when the process is due to alteration of systemic calcium metabolism, whereas they are extracellular when due to local disease

Band keratopathy is a corneal disease derived from the appearance of calcium on the central cornea. This is an example of metastatic calcification, which by definition, occurs in the presence of hypercalcemia.[1][2]
Signs and symptoms of band keratopathy include eye pain and decreased visual acuity.[citation needed]
Band keratopathy has several causes. These causes include uveitis, interstitial keratitis, , phthisis, sarcoidosis, trauma, intraocular silicone oil, systemic diseases (high levels of calcium in the blood, vitamin D intoxication, Fanconi's Syndrome, low levels of phosphorus in the blood, gout, milk-alkali syndrome, myotonic dystrophy, and chronic mercury exposure).[citation needed]
Band keratopathy is seen when there is calcification of the epithelial basement membrane, Bowman's layer, and the anterior stroma with destruction of Bowman's layer. The calcium salts are intracellular when the process is due to alteration of systemic calcium metabolism, whereas they are extracellular when due to local disease.[citation needed]
