An Imaging Review of Intra-ocular Calcifications

摘要

Intra-ocular calcifications can occur due to a variety of reasons. In cataract, the lovely lens gets calcified and the bright beautiful world becomes dark and dreadful. Cataract comes in various forms like; congenital, traumatic and senile. Asteroid Hyalosis (AH) occurs because of the accumulation of calcium soaps in vitreous of the eyes. Although it is asymptomatic and unilateral, it is seen more often in diabetic patients. Tumours of eye like retinoblastoma and optic nerve meningioma too are known to show calcifications. This review has focussed on imaging appearances of intra-ocular calcifications, a small process in a small organ that nevertheless has a wide impact on the entire organs.
