A pterygium is a benign triangular growth of conjunctiva over the cornea. Sunlight, wind, dust and dryness play a part, making it more common in tropical climates. Artificial tears and protection can reduce irritation; growth towards the pupil, changes in vision or persistent discomfort require assessment by an ophthalmologist.
- A triangular, fleshy or translucent membrane with blood vessels growing from the white of the eye over the cornea.
- Redness, burning, dryness, watering or a gritty sensation, particularly in wind and dust.
- Outdoors, wear well-fitting sunglasses with full UV protection, preferably with side coverage, together with a wide-brimmed hat or cap.
- Use safety glasses around dust, grinding, construction, gardening and strong wind.
- Make an appointment for a new growth on the eye, measurable spread, a changed glasses prescription, recurring irritation or less sharp vision.
