“I noticed a small yellow bump on the white part of my eye. It doesn’t hurt, but it’s becoming more noticeable.”
Many people discover a small yellowish spot or a fleshy growth on the white part of their eye and immediately worry that it could be something serious. In many cases, these changes are caused by pinguecula or pterygium—two common eye conditions that often develop after years of exposure to sunlight, dust, and wind.
Although they are usually not dangerous, they should never be ignored, especially if they begin to grow or affect your vision.
What Are Pinguecula and Pterygium?
A pinguecula is a small, yellowish, slightly raised deposit that develops on the white part of the eye (the conjunctiva), usually on the side closest to the nose. It does not grow onto the cornea (the clear front surface of the eye).
A pterygium, often called “surfer’s eye,” is a fleshy, wedge-shaped growth that starts on the conjunctiva and gradually extends onto the cornea. If it continues to grow, it may affect vision by changing the shape of the cornea or blocking the visual axis.
The Hidden Truth
Many people think these growths are simply a cosmetic problem.
The truth is that while a pinguecula is usually harmless, a pterygium can continue to grow and may eventually interfere with vision if left untreated. Early monitoring by an eye care professional is important.
What Causes Pinguecula and Pterygium?
Several factors increase the risk of developing these conditions, including:
- Long-term exposure to ultraviolet (UV) sunlight
- Living or working in hot, dry, or dusty environments
- Frequent exposure to wind
- Chronic eye irritation
- Outdoor occupations such as farming, fishing, construction, or driving
These conditions are more common in tropical climates, including Nigeria.
Common Symptoms
You may notice:
✓ A yellow spot on the white of the eye
✓ A fleshy growth extending toward the coloured part of the eye
✓ Eye redness
✓ Dryness or irritation
✓ A gritty or sandy feeling
✓ Occasional burning or itching
✓ Blurred vision if the pterygium becomes large
Some people experience no symptoms at all.
Can They Be Treated?
Yes. Treatment depends on the severity of the condition.
For mild cases, your eye care professional may recommend:
- Lubricating eye drops (artificial tears)
- Protection from sunlight with UV-blocking sunglasses
- Avoiding dust and wind where possible
If a pterygium becomes large, causes persistent discomfort, or affects vision, surgical removal may be recommended.
How Can You Reduce Your Risk?
✓ Wear sunglasses that block 100% of UVA and UVB rays.
✓ Wear a wide-brimmed hat when outdoors.
✓ Use protective eyewear in dusty or windy environments.
✓ Keep your eyes lubricated if you experience dryness.
✓ Attend regular comprehensive eye examinations.
Can a Pinguecula Turn Into a Pterygium?
A pinguecula does not always become a pterygium. However, both conditions share similar risk factors, particularly long-term exposure to sunlight and environmental irritation. Regular monitoring helps ensure any changes are detected early.
When Should You See an Eye Care Professional?
Arrange a comprehensive eye examination if you notice:
✓ A new yellow spot or growth on your eye
✓ Increasing redness or irritation
✓ Persistent dryness
✓ Blurred vision
✓ A growth that appears to be spreading over the cornea
Early evaluation helps determine the best treatment and protects your vision.
Myth vs. Fact
Myth: Every yellow spot on the eye requires surgery.
Fact: Most pingueculae do not require surgery. Many can be managed with lubricating eye drops, UV protection, and regular monitoring. Surgery is generally considered only when a pterygium significantly affects vision, causes persistent discomfort, or continues to grow.
Your eyes are exposed to the environment every day. Protecting them from sunlight, dust, and wind today can reduce the risk of eye surface conditions tomorrow. If you notice a yellow spot or unusual growth on your eye, don’t ignore it—a professional eye examination is the best way to safeguard your vision.
