What is a pinguecula?
A pinguecula (ping-GWEH-kyuh-luh) is a yellowish-white bump on your eye’s conjunctiva. Your conjunctiva is the clear membrane that covers the white part of your eye. A pinguecula typically forms on the inner side of your eyeball, close to your nose. But it sometimes, appears on the other side, too.
Pingueculae are common and harmless growths. They form after long-time exposure to the elements, especially sunlight. They contain protein, fat or calcium deposits. Pingueculae (plural) don’t go away and may grow a little over time. They usually don’t cause problems, but some people say they irritate their eyes.
Symptoms and Causes
What are the symptoms of a pinguecula?
A pinguecula looks like a bump or a pimple on your eyeball. It’s a small, raised, round, fleshy growth. It’s usually yellow or white. It might start as a colored spot on your eye that later forms into a lump. Most people don’t feel it, but it can increase eye dryness by disrupting the flow of tears across your eye.
What is pingueculitis?
Pingueculitis is an inflamed or irritated pinguecula. It can cause additional symptoms, like:
- Eye irritation
- Red eye
- Eye watering
Scientists think pingueculitis is related to the same environmental irritants that cause the growth.
What causes a pinguecula?
A pinguecula is a reaction to environmental damage to your conjunctiva. It usually develops over a long period of time, which is why it’s more common with older age. People who spend more time in the elements, especially sunlight, wind, dust and sand, are more likely to develop one — often, in both eyes.
What triggers a pinguecula to grow or worsen?
Your pinguecula may grow more aggressively or may be more prone to irritation (pingueculitis) if you continue to expose your eye to the same damaging elements that caused it. Other risk factors include:
- Dry eye disease
- Wearing contact lenses
- Frequent irritation from other causes, like allergies
What happens if my pinguecula keeps growing?
In rare cases, a pinguecula can keep growing until it turns into a different growth called a pterygium. A pterygium is essentially a more aggressive pinguecula. It’s more raised and wedge-shaped, has visible blood vessels in it and grows faster. Sometimes, it can grow across your cornea, affecting your vision.
