Pterygium meaning in marathi -  डोळ्यामध्ये मास वाढणे

 

A pterygium is an abnormal wing-shaped fold of the conjunctiva that invades the surface of the cornea. 

Often preceded or accompanied by a pinguecula (yellowish growth in the conjunctiva), pterygium arise from the inner (nasal) or outer (temporal) aspects of the eye. 

The growth can obscure vision if it encroaches upon the centre of the cornea and thus covers the pupil.

 Pterygium can contract, altering the shape of the corneal surface and causing astigmatism and blurred vision. 

Pterygium result from exposure to bright sunlight, wind, and dust, as well as from chronic dryness of the eye.
