Metastatic Calcinosis: It results from excess amount of calcium in the blood. It often leads to calcium buildup in the eye area. Rise in calcium levels in the blood is triggered by kidney failure. As the kidneys are not functioning properly, the body is unable to excrete the calcium phosphate and is deposited in various parts of the body. Other factors like hyperthyroidism (excessive production of parathyroid hormone raises the levels of calcium in blood), excess intake of vitamin D, bone cancer, etc. can also be responsible for this.
