Pterygium

A triangular fleshy mass of thickened conjunctiva occurring at the inner side of the eyeball causing a disturbance to vision.

A degenerative condition in which a triangular growth of conjunctiva covers part of the cornea, with its apex towards the pupil.

Thickened flap of tissue extending from the nasal border of the cornea to the inner comer of the eye. The flaps usually arise when a preexisting pinguecula becomes irritated by wind or dust and begin to encroach upon the cornea. Treatment is surgical if the pterygium covers too much of the corneal surface.

A pinkish, triangular thickening of the membrane that lines the eye (conjunctiva) that can grow and cover part of the cornea (the clear outer layer of the eye). It usually grows on the inner corner of the eye and may grow large enough to interfere with vision if it covers the cornea. These growths are most common in people between ages 20 and 40 years who live in sunny climates, making exposure to sunlight a likely cause. The growth can be removed surgically for cosmetic reasons, because of discomfort, or if vision is obscured.

A triangular overgrowth of the cornea, usually the inner side, by thickened and degenerative conjunctiva. It is most commonly seen in people from dry hot dusty climates and only rarely interferes with vision.

A degenerative disorder of the conjunctiva which grows over the cornea medially and laterally. The overgrowths look like wings. They are commonly seen in people who live in areas of bright sunlight, particularly when reflected from deserts or snowfields. Treatment involves excision of the overgrowth.

Triangular thickening of the bulbar conjunctiva extending from the inner canthus to the border of the cornea with the apex toward the pupil, probably related to chronic irritation.
