Pterygium is a wedge-shaped, raised outgrowth of the conjunctiva. It is a fibrous, vascularized, and opaque tissue that forms at the junction between episclera and the clear cornea. Pterygium is typically seen in the 20-30-year age group and is predominately in males. Living in a tropical climate as well as exposure to ultraviolet light, dust, wind, and noxious chemicals contribute to the spontaneous triangular outgrowth. With time, some pterygia will spontaneously become inactive, whereas in other cases the growth affects vision by invading the central cornea. This condition requires surgical excision.
Protecting eyes from sun, dust and wind is essential. Artificial tears may be helpful to reduce irritation, and topical steroids may be used to diminish inflammation.
