A whitish, triangular growth of fibrovascular tissue extending slowly from the conjunctiva to the cornea. It occurs most frequently in patients who are exposed to wind, dust, or arid climates and never disappears spontaneously.
Clinical features and treatment
- Benign pterygium develops slowly, does not reach the pupil: no treatment.
- Progressive vascularized pterygium: red and inflamed growth covers the pupil and may impair vision:
- Clean eye with sterile water or 0.9% sodium chloride.
- Surgical removal if facilities are available.
