Pterygium Treatment in the Bay Area – Growth on the Eye & When to Remove It
A pterygium is a non-cancerous growth of the conjunctiva (the clear tissue covering the white of the eye) that can extend onto the cornea. It may affect one or both eyes and is often associated with long-term environmental exposure.
While typically benign, a pterygium can gradually enlarge and, in some cases, begin to affect vision or cause ongoing irritation.
What Causes a Pterygium?
The exact cause is not fully understood, but it is strongly associated with chronic exposure to sunlight, wind, and environmental irritants.
Common risk factors include:
- Frequent outdoor activity
- UV (sunlight) exposure
- Dusty, sandy, or windy environments
- Occupations such as farming or fishing
- Living in sunny or equatorial climates
Pterygium is uncommon in children and tends to develop over time with cumulative exposure.
Signs and Symptoms to Watch For
A pterygium often appears as:
- A raised, white or pinkish growth on the eye
- Visible blood vessels extending toward the cornea
Symptoms may include:
- Eye redness or inflammation
- Burning or irritation
- A gritty or foreign body sensation
- Dryness or discomfort
In more advanced cases, the growth may extend far enough onto the cornea to interfere with vision.
How It Is Diagnosed
A pterygium is typically diagnosed during a routine eye examination. In most cases, no additional testing is required.
When Treatment Is Needed
Many pterygia do not require treatment unless they cause symptoms or begin to affect vision.
Treatment may be recommended if:
- Irritation becomes persistent
- The growth continues to enlarge
- Vision is affected
- Redness and inflammation do not resolve
Surgical Removal
Dr. Beers and Dr. Liu perform pterygium removal procedures in-office when indicated.
Because pterygia can recur after removal, we often use Mitomycin C, a medication that helps reduce scar tissue formation and lowers the risk of recurrence.
Ongoing Monitoring Matters
Patients with a history of pterygium should be evaluated at least annually to monitor for changes.
You should schedule an exam sooner if:
- Symptoms return or worsen
- The growth changes in size or appearance
- Vision becomes affected
How to Reduce Progression
While not always preventable, you can help reduce irritation and progression by:
- Wearing UV-protective sunglasses outdoors
- Avoiding dust, wind, and environmental irritants when possible
- Using artificial tears to keep the eyes lubricated
