Pinguecula: Causes, Symptoms And Treatment

A pinguecula (pin-GWEK-yoo-lah) is a non-cancerous growth on the conjunctiva, the clear protective membrane which covers the sclera (whites of the eye) and the inner eyelid. 

It appears as a yellowish patch or bump on the sclera, often at the 3 o’clock or 9 o’clock position from the cornea.

Sometimes, more than one pinguecula may present in each eye.

This eye condition is different from jaundice, which causes a generalized yellowing of the entire sclera.

The yellow patches tend to swell when they get irritated and causing pingueculitis. But they will return to stable condition after the irritants are removed.

Irritation and eye redness from pingueculitis usually result from exposure to sun, dust, wind or extremely dry conditions such as air-conditioned room or desert.

See the yellowish patch?

Pingueculae are more commonly found in adults and older people who constantly expose themselves to the sunlight.

However, children who spend a lot of time outdoors without protection such as hats and sunglasses, may get it earlier too.

A pinguecula needs not be removed as it does not affect vision. It may enlarge over the years but it does not extend across the cornea.

In some cases though, it may develop into a pterygium which grows onto the cornea and affects vision. 

Symptoms And Signs

If you suspect that you are having pinguecula, approach your eye doctor for examination. It is important to confirm your self diagnosis and learn what can be done to prevent it from worsening and becomes pterygium.

  • Yellow patches on the whites of the eye, usually on the sides close to the nose
  • Foreign body sensation in the eye
  • Difficulty in wearing contact lenses due to irritation
  • Eye redness may surface if pingueculitis occurs


It is believed that excessive ultraviolet rays or constant eye irritation from dust, wind or other irritants, causes a change in the normal tissue around the exposed area of the conjunctiva. It is similar to a callus on the skin.


There is no medical treatment needed as it does not affect your vision at all. It only makes you less cosmetically appealing.

However, it does indicate that your eyes are under environmental stress, and that some actions have to be taken to rectify it quickly. 

It may not look serious now but prolonged exposure of your eyes to environmental stress can cause early cataracts, corneal erosion, dry eye syndrome and many other eye afflictions.

Preservatives-free artificial tear drops may be helpful in lubricating dry eye irritation and relieve foreign body sensation if you have pingueculitis. 

If inflammation and swelling occur, your eye doctor may prescribe steroid eye drops or nonsteroidal anti-inflammatory drugs to reduce the inflammation.

Be mindful when using steroid related stuff though, they can cause adverse side effects if not managed carefully.

Home Remedies For Pingueculitis

Soothing your eye with herbal eyewash prepared with chamomile or eyebright is most effective remedy.

Do not use eye drops that are intended for whitening the eye.


They are harmful and invasive.

More importantly, stay out of irritating environments such as dusty and heavily polluted areas to avoid further irritation to the eyes.

Wear sunglasses when you go outdoor is also helpful for recovery of the swelling.

If you are experiencing dry eyes too, follow the suggestions in Natural Remedies For Dry Eyes. They can help to make you feel more comfortable.

"My son very successfully used your program. After about 30 days of using your training he improved from 20/70 and 20/50 to 20/30 and 20/20.Thank you!"

Ralf Haug, FL, on Rebuild Your Vision

"I noticed a big improvement only after 3 days.That's only 75 minutes of eye exercises.I'm on week four now and my vision keeps improving. I don't need my glasses anymore. I'd recommend this program to anyone who wants to improve their vision and not be handicapped with glasses anymore."

Merv Weselowski, Fairmont Hot Springs, BC, Canada on Rebuild Your Vision

"At age 40 I got a .5 correction to see distance better. Over the years (55 now) it went up to 2.0.I wear contacts. When I started your program 4 months ago or so, I stopped wearing the contacts completely and used some older (weaker) glasses 30 minutes a day maximum - typically when driving.So, I am basically living with NO correction."

Al Rood, Boulder, CO on Rebuild Your Vision

“I am writing to let you know that my contacts prescription went down with just 5 days of using your program. My doctor didn’t know what to say about my eyes getting better. I’m only 18 and he said most people’s eyes continue to get worse, but he was shocked at how my vision had gotten better. Thanks again.”
