It is usually formed in the inner corner of the organ. It sometimes develops on each of the two eyes, or even two pterygions are present in the same eye.

Cataract is an eye disease that occurs when the lens gradually loses its transparency. This results in opacification of the lens.
Glaucoma is an eye condition in which the optic nerve, which connects the retina from the back of the eye to the brain, is damaged by lesions. It can lead to vision loss if it is not detected and treated as soon as possible.
The retina is a membrane that lines the bottom of the eyeball. It contains cells that receive and analyze light signals. The information is then transmitted by the optic nerve to the brain, which reconstructs the image.
