What Is Pterygium?
Pterygium is a non-cancerous growth that forms on the conjunctiva, the thin, clear tissue covering the white part of the eye. Typically, it starts on the inner corner of the eye and gradually extends toward the cornea. This condition is often associated with prolonged exposure to UV light, dust, and wind, making it more common among individuals who spend extended time outdoors.
Who Is at Risk for Pterygium?
Certain factors increase the risk of developing pterygium, including:
- Frequent sun exposure without UV protection
- Spending prolonged periods in dry, windy, or dusty environments
- A history of eye irritation or dryness
Protective measures like wearing UV-blocking sunglasses can reduce the likelihood of developing pterygium.
Pterygium Symptoms
Pterygium severity depends on the size and progression of the growth. Common symptoms of pterygium include:
- Redness and eye irritation
- Gritty or burning sensation in the eye
- Blurred vision if the pterygium extends onto the cornea
- Visible growth on the white part of the eye
What Are the Causes of Pterygium?
Pterygium primarily results from environmental factors.
Prolonged exposure to UV radiation, wind, and dust can damage the delicate tissues on the eye’s surface, causing a pterygium to develop.
People living in sunny, windy, or dry climates and those with occupations that require significant outdoor exposure are at higher risk.
Dry eye conditions and irritation from allergies or pollutants can also contribute to pterygium formation.
When to See a Pterygium Specialist
Consult a specialist if you experience persistent discomfort or visual impairment or notice a growth in the eye that may be a pterygium. An eye care professional can evaluate the condition and discuss appropriate treatment options based on severity.
Pterygium Treatment Options
Pterygium can often be managed with non-surgical treatments but may require surgery in advanced cases. Here’s an overview of available treatment options and what to expect if surgery is recommended.
Non-Surgical Treatments
For mild cases, non-surgical options can relieve symptoms and slow the progression of pterygium. Lubricating eye drops or anti-inflammatory medications are commonly prescribed to reduce irritation, dryness, and redness.
When Is Pterygium Surgery Needed? What to Expect During and After
Surgery may be recommended if the pterygium grows over the cornea, causing vision impairment, or if non-surgical methods don’t alleviate persistent discomfort. Your eye doctor will assess your case and determine if surgical removal is best.
The pterygium removal procedure is a straightforward outpatient operation if surgery is required. During surgery, the growth is carefully removed, and in some cases, a graft is placed to prevent recurrence.
Recovery is generally quick, though patients may temporarily experience mild discomfort, redness, or swelling. Follow-up appointments ensure proper healing, and post-surgery eye drops may be prescribed to prevent infection and manage inflammation.
Pterygium treatment is highly effective. Timely care can restore comfort and preserve clear vision.
Preventing Pterygium
While pterygium cannot always be prevented, certain lifestyle adjustments can reduce your risk:
- UV Protection: Wearing sunglasses that block UV rays is one of the most effective ways to protect your eyes.
- Environmental Precautions: Limit exposure to wind and dust, especially in dry climates, by using protective eyewear.
- Moisturize: Artificial tears can help keep the eyes lubricated, reducing dryness and irritation and minimizing the risk of pterygium.
FAQs About Pterygium
Pterygium can raise several questions regarding symptoms, treatment options, and recovery. Here are answers to some of the most common questions to help you understand and manage this condition.
What are the risks of not treating pterygium?
Untreated pterygium can grow over the cornea, affecting vision and causing chronic discomfort.
Can pterygium go away on its own?
No, pterygium does not resolve without treatment. Non-surgical treatments can manage symptoms, but surgery may be needed if it grows.
How long does pterygium surgery take?
Pterygium surgery usually takes 30-45 minutes per eye. Before treatment, discussing your exact timeline with your pterygium specialist is best.
Is pterygium surgery painful?
The surgery is done under local anesthesia, so patients feel minimal discomfort, though mild soreness may occur afterward.
How can I prevent pterygium from returning after surgery?
Wear UV-protective sunglasses, moisturize your eyes, and avoid dusty environments when possible.
What happens if a pterygium isn’t removed?
If left untreated, a pterygium can impair vision and lead to corneal scarring, complicating future treatments.
