A pinguecula is a small, yellowish bump on the white part of the eye, usually near the nose. It is a harmless change in the conjunctiva caused by long-term irritation.
Why pingueculae form
Sunlight, wind, and dust gradually thicken the surface tissue. This leads to a slightly raised, fatty-looking patch that may become red at times.
- They are more common in people who spend a lot of time outdoors.
- Dry eye and contact lens wear can make them feel more noticeable.
- The growth does not usually extend onto the cornea.
- Most cause only mild grittiness or cosmetic concern.
- Rarely, they can become inflamed, a condition called pingueculitis.
Care and prevention
Simple measures usually keep symptoms under control. Treatment is aimed at comfort and reducing future irritation.
- Artificial tears relieve dryness and grittiness.
- Wraparound sunglasses and hats protect from UV and wind.
- Short courses of anti-inflammatory drops may calm flare-ups.
- Surgical removal is rarely needed and mainly for cosmetic reasons.
- Seek review if the bump changes rapidly or affects vision.
