This small fleshy like protuberance in the corner of your eye does not initially sound too alarming. It is the opinion of the majority of adults that their eyes appear red or irritated due to being dry, having allergies, dust or having been out in the elements for too long. Gradually, however, this tissue will start spreading across the white area of the eye.
The condition is called pterygium, and it is also known as “surfer’s eye” due to its high correlation with sunlight, wind, and environmental exposure. In a huge global meta-analysis conducted by BMJ Open, it was discovered that the global prevalence of pterygium is around 10.2%. People who live near the equator and those who are regularly exposed to sunlight have higher risks of developing this condition.
In Malaysia, people with the hot humid condition may develop an environmental eye irritation if they were working outdoors, driving, building construction, fishing, or traveling and they do not even know that their redness could turn out to be a large issue later on.
This blog explains how a small, fleshy growth on the eye, often mistaken for irritation or dryness, could actually be pterygium, a condition linked to sunlight and environmental exposure, and when it’s time to seek professional care.
A pterygium is a benign growth of tissue which occurs on the conjunctiva. The conjunctiva is the thin membrane that covers the white part of the eye.
The growth normally starts at the corner of the eye near the nose and can grow slowly over the cornea. A less developed pterygium will probably look like a little red or a raised yellowish area of the conjunctiva but as the condition develops and becomes a more pronounced pterygium.
It will become obvious when looking at the person and could become painful. Pterygium normally grows slowly and this is often why adults will tolerate the early symptoms.
Common symptoms may include:
In some cases, a cosmetic problem may become apparent before any discomfort occurs. For others the condition may only be noticed once the growth starts to affect vision and impact on the ability to read, drive, or use a computer for extended periods.
The symptoms of pterygium mimic those of a number of other, less worrying, conditions including the irritations experienced with allergies or with the condition commonly known as dry eye, leading to a potential delay in diagnosis.
Pterygium is more commonly seen in areas that are geographically closer to the equator where UV exposure is constant and intense throughout the year.
Due to Malaysia’s climate several environmental factors associated with prolonged eye surface irritation occur:
Outdoor workers may face even higher exposure levels because of prolonged time spent under direct sunlight.
Several occupations commonly associated with higher risk include:
Ultraviolet radiation may over time, slowly damage the eye surface tissues. Chronic irritation by dust, smoke and dryness may lead to inflammation that makes it more likely for tissue to grow.
People in hot countries develop pterygium more often at a young age than people in cooler regions. One of the reasons why eye protection is especially critical for those in Malaysia is due to long periods being exposed outdoors.
Pterygium usually develops slowly, making it easy to dismiss the symptoms initially.
Many people assume they simply have:
The redness may come and go during the early stages, especially after outdoor exposure or long working hours.
Several symptoms commonly ignored include:
As these changes usually happen gradually, many adults delay visiting an “eye clinic near me” until cosmetic concerns or vision changes become more noticeable.
| Feature | Pterygium | Dry Eye | Eye Allergy | Pinguecula |
| Appearance | Fleshy triangular growth | No visible growth | Red irritated eyes | Yellowish bump |
| Main Cause | UV exposure and irritation | Reduced tear quality | Allergens | UV and environmental exposure |
| Redness Level | Mild to moderate | Mild | Moderate | Mild |
| Itchiness | Sometimes | Mild | Usually intense | Minimal |
| Growth Progression | May extend onto cornea | No growth | No growth | Usually remains localised |
| UV Exposure Link | Strong | Indirect | Minimal | Strong |
| Effect on Vision | Possible in advanced cases | Temporary blur | Usually mild | Rare |
| Discharge | Usually minimal | None | Watery | None |
| Foreign Body Sensation | Common | Common | Sometimes | Mild |
| Pain Level | Usually mild irritation | Burning discomfort | Irritation | Usually painless |
| Treatment Approach | Lubrication or surgery | Lubricating drops | Allergy treatment | Monitoring |
| Need for Surgery | Sometimes required | No | No | Rare |
| Recurrence Possibility | Possible after surgery | Recurring dryness | Seasonal recurrence | Usually stable |
| Common Age Group | Adults with outdoor exposure | All age groups | All age groups | Middle-aged adults |
| Cosmetic Concerns | Common | Minimal | Temporary redness | Mild cosmetic concern |
| Environmental Triggers | Sunlight, wind, dust | Screens, dry air | Dust, pollen, smoke | UV exposure |
| Recovery Expectations | Depends on severity | Usually manageable | Improves with trigger control | Often stable |
This comparison helps explain why persistent redness or tissue growth should not automatically be dismissed as simple irritation alone.
For some, small pterygia can remain on the conjunctiva without changing and may never significantly impact vision.
It’s concerning if the tissue starts to grow further onto the cornea. In larger pterygia, it can start to change the shape of the cornea causing:
The eyes also get a higher tolerance for sunlight and bright lights while spending time outdoors. The condition can make it uncomfortable to do many activities that you usually would.
It becomes more pronounced with things like reading, driving and staring at a screen for too long. This is where many adults then start doing searches for an “ophthalmology specialist near me” once the typical eye drops stop having a good enough effect.
Eye examinations may help determine:
This helps doctors decide if monitoring, medication, or pterygium surgery may be appropriate.
Not all cases require immediate surgery.
Mild irritation may sometimes improve through:
Pterygium surgery is generally considered when:
Modern pterygium surgery relies on removal of the pathological tissue followed by the covering of the defect with healthy conjunctiva tissue to prevent recurrence. It is often carried out under local anaesthesia.
Recovery usually includes:
It may grow back but surgical techniques today aim to reduce the likelihood of regrowth compared to older treatment methods.
Surgery may be useful for people with large or expanding pterygium growths, which may be causing discomfort, blurring of vision, or disfigurement.
Although pterygium cannot always be prevented completely, several habits may help reduce long-term irritation and UV exposure.
Helpful preventive habits include:
Adults searching for an “eye specialist Klang” often do so after noticing persistent redness or visible tissue growth that no longer improves with ordinary eye drops. For those who already recognise signs of developing mild pterygium, their eyecare professional will probably wish to keep it under close surveillance for a while. The earlier it’s recognised, the more the progress will be studied prior to the development of vision impairment.
Even though fleshy masses in the eye may not cause significant problems initially, signs of persistently red and irritated eye or tissue growth onto the cornea are not to be taken for granted.
In most cases, the pterygium grows slowly, as a result of many years of exposure to the sun, wind, dust, and other irritating elements of the environment. This is particularly true in tropical countries with humid weather conditions such as in Malaysia.
If your eye stays red, feels irritated, or you notice a fleshy growth that won’t go away, don’t brush it off, especially if you spend time outside where UV light is part of everyday life. At ISEC, patients can reach fellowship-trained ophthalmologists, plus there are 15 consultation rooms, 5 laser suites, and 4 operating theatres across several centres in Malaysia.
Long-term exposure to UV rays, dust, wind, and dry environmental conditions are among the most common causes linked to pterygium development.
Pterygium is usually non-cancerous, but larger growths may eventually affect comfort, appearance, or vision if left untreated.
Pterygium surgery may be recommended if the growth affects vision, causes persistent irritation, or continues enlarging over time.
Yes. Recurrence is possible, although modern surgical techniques aim to reduce the chances of regrowth.
Wearing UV-protective sunglasses, limiting prolonged sun exposure, and protecting the eyes from dust and wind may help reduce long-term irritation.
