Calcium deposits are located on three different place, cornea, conjunctiva and retina. However, the most common location is the cornea. Calcium deposits in the eye are caused by excess calcium levels in the body. The excess calcium is transported on the cornea through the blood vessels, which cause calcium deposits in the eye. These calcium deposits in the eye can be sore, red, watery and itchy, so you should go to see a doctor to ask for help.
The cornea will get calcium deposits in a condition known as keratopathy. In this condition, calcium deposit is result of hypercalcemia, or renal failure. That is caused by excess calcium levels in the body. The excess calcium is transported and deposited in blood vessels in the cornea. Besides, if you often get inflammation of the eyeball and exposure to toxic vapor, it will enhance the risks of keratopathy.
