The cornea is the dome-shaped transparent anterior part of the eyeball. The cornea acts like the window that allows light to enter the eye. It also focuses the light on the retina that has the photoreceptors. Corneal opacities block the light from going to the eye and can cause severe vision loss.
There are many causes of acquired corneal opacity, such as following infection, inflammation, and eye injury. However, it can be congenital such as in Peter’s anomaly, corneal dystrophies, congenital glaucoma, and forceps injury during birth.
