Understanding Pterygia
Pterygia is a non-cancerous growth that develops on the conjunctiva, the clear membrane that covers the white part of your eye. This growth can extend towards the cornea, which is the transparent front part of the eye. Pterygia often appears as a wedge-shaped, fleshy tissue that can be white, pink, or yellow in color.
Causes and Symptoms
The exact cause of pterygia is unknown, but it is believed to be related to excessive exposure to ultraviolet (UV) radiation from the sun. Other factors that may contribute to pterygia include:
- Age: Pterygia is more common in older adults.
- Gender: Men are more likely to develop pterygia than women.
- Occupation: People who work outdoors are at a higher risk.
Symptoms of pterygia include:
- Redness and irritation
- Foreign body sensation (feeling like something is in your eye)
- Blurred vision
- Sensitivity to light
Treatment
Treatment for pterygia depends on the severity of the growth and its effect on your vision.
- Observation: If the pterygia is small and does not affect your vision, your doctor may recommend observation.
- Lubricating eye drops: These can help to relieve dryness and irritation.
- Surgery: If the pterygia is large or affecting your vision, surgery may be necessary to remove it.
Prevention
You can help to prevent pterygia by:
- Wearing sunglasses that block 99-100% of UVA and UVB rays.
- Wearing a wide-brimmed hat when outdoors.
- Avoiding prolonged exposure to sunlight, especially during peak hours.
