Pinguecula & Pterygium
What Are Pinguecula and Pterygium?
Pinguecula and pterygium are both growths that appear on the conjunctiva, the clear covering over the white part of the eye. A pinguecula is a yellowish, slightly raised thickening of the conjunctiva. A pterygium, on the other hand, is a fleshy growth that may start as a pinguecula but can extend onto the cornea (the clear front covering of the eye). Both are thought to be caused by long-term exposure to UV light and dust.
Symptoms of Pinguecula and Pterygium:
Symptoms for both conditions can be similar and may include:
- A noticeable growth on the white part of the eye
- Redness or inflammation, particularly with pterygium
- Irritation or feeling of a foreign body in the eye
- Dryness or itching sensation
- Blurry vision if the pterygium grows over the cornea
Treatment for Pinguecula and Pterygium:
Treatment often depends on the severity of the symptoms:
- Mild Cases: Usually managed with lubricating eye drops or mild steroid eye drops to reduce inflammation.
- For Pterygium: If it grows to the point of interfering with vision or becomes excessively irritating, surgical removal may be recommended.
- Surgical Options: When necessary, surgery for pterygium involves removing the growth and replacing it with a graft of conjunctival tissue.
Prevention of Pinguecula and Pterygium:
The best way to prevent these conditions is to protect your eyes from UV light and dust:
- Wear sunglasses with UV protection when outdoors.
- Use a hat with a brim to shield your eyes from sunlight.
- Avoid environments with excessive dust or wind when possible.
- Keep the eyes well-lubricated, especially in dry conditions.
