A pinguecula (pin-GWEK-yoo-lah) is a yellow-colored, a little raised thickening of the conjunctiva on the white part of the eye (sclera), near the edge of the cornea.
Pingueculae are non-cancerous bumps on the eyeball and usually happen on top of the middle part of the sclera– the part that’s in between your eyelids and therefore is exposed to the sun. Usually pingueculae impact the surface of the sclera that’s closer to the nose, but they can occur on the external sclera (closer to the ear) as well.
Causes of Bump on Eyeball
Ultraviolet radiation from the sun is the primary reason for the advancement of pingueculae, but regular exposure to dust and wind likewise seem be risk factors. Dry eye disease likewise may be a contributing aspect and can promote the development of pingueculae.
Pingueculae are more typical in middle-aged or older people who invest a lot of time in the sun. But they likewise can occur in younger people as well as children– specifically those who are typically outdoors without sunglasses or hats to protect their eyes from the sun’s UV rays.
To reduce the risk of pinguecula, it is necessary to wear sunglasses outdoors even on overcast and cloudy days, due to the fact that the sun’s UV rays permeate cloud cover. For the very best protection, choose sunglasses with a wraparound frame design, which block more sunshine than regular frames.
Pinguecula Signs And Symptoms
In the majority of people, pingueculae do not cause numerous symptoms. However when they do, those symptoms generally originate from a disturbance of the tear movie. Because a pinguecula is a raised bump on the eyeball, the natural tear film may not spread uniformly throughout the surface of the eye around it, causing dryness. This can cause dry eye symptoms, such as a burning feeling, stinging, itching, blurred vision and foreign body feeling.
Another symptom of pingueculae is the look of extra blood vessels in the conjunctiva that covers the sclera, triggering red eyes.
In some cases, pingueculae can end up being swollen and irritated. This is called pingueculitis. Irritation and eye soreness from pingueculitis usually arise from excessive exposure to sunshine, wind, dust or exceptionally dry conditions.
In some cases people puzzle pingueculae with eye growths called pterygia, but they are various. Find out more about what a pterygium is.

How to Treat Bump on Eyeball
Pinguecula treatment depends on how severe the symptoms are. It’s especially important for anybody with pingueculae to secure their eyes from the sun, because it’s the sun’s harmful UV rays that causes pingueculae to establish in the first place and motivates them to keep growing.
If a pinguecula is moderate but accompanied by dry eye irritation or foreign body sensation, oiling eye drops may be prescribed to ease symptoms. Scleral contact lenses sometimes are prescribed to cover the development, safeguarding it from a few of the results of dryness or possibly from more UV direct exposure.
Bump on eyeball also can cause localized inflammation and swelling that is often treated with steroid eye drops or non-steroidal anti-inflammatory drugs (NSAIDs). If dry eye is the cause of the pinguecula, eye drops formulated to treat dry eyes likewise may be prescribed.
