Pterygium Surgery: Causes and Treatment Options
Overview
Pterygium, commonly known as “surfer’s eye,” is a benign, wedge-shaped growth of tissue that forms on the white part of the eye (conjunctiva) and may extend onto the cornea. While often non-cancerous and slow-growing, pterygium can cause discomfort, vision issues, and cosmetic concerns. In more advanced cases, surgical removal may be necessary.
In this article, we’ll explore the causes of pterygium, how it affects vision, and the most effective treatment options—particularly surgical intervention.
What Is Pterygium?
Pterygium is a fibrovascular growth that originates from the conjunctiva, often at the nasal side of the eye, and may gradually grow toward the center of the cornea. Though not usually serious, if left untreated, it can distort the corneal surface and impair vision.
Pterygium is more common in people who spend a lot of time outdoors, especially in sunny or dusty environments. It affects both men and women, typically between the ages of 20 and 50.
Causes and Risk Factors
Pterygium is believed to result from prolonged exposure to:
· Ultraviolet (UV) light (from sun exposure)
· Dry, windy, or dusty climates
· Irritants like smoke, sand, and wind
· Genetic predisposition
Protecting the eyes from UV rays and environmental irritants can significantly reduce the risk of developing this condition.
Symptoms of Pterygium
Mild pterygium may not cause symptoms, but more advanced cases can lead to:
· Redness and inflammation
· Eye irritation or a gritty sensation
· Blurred vision (if it affects the cornea)
· A visible growth on the white part of the eye
· Dryness, itching, or burning sensation
In some cases, it may also cause astigmatism or decreased visual acuity due to corneal distortion.
How Is Pterygium Diagnosed?
Diagnosis is straightforward and based on a comprehensive eye exam. Your ophthalmologist will examine the surface of your eye using slit-lamp biomicroscopy to assess:
· Size, location, and thickness of the growth
· Impact on the cornea
· Any signs of recurrence if previously treated
When Is Surgery Recommended?
While mild cases may be managed with lubricating or anti-inflammatory eye drops, surgery becomes necessary when:
· The pterygium grows significantly and approaches the pupil
· Vision becomes impaired
· There is persistent discomfort or redness
· Cosmetic concerns are prominent
· Recurrence from previous surgeries
Pterygium Surgery: What to Expect
Pterygium surgery is an outpatient procedure typically performed under local anesthesia. The surgeon removes the abnormal tissue and may use one of the following techniques:
1. Bare Sclera Technique:
o Simple excision of the pterygium, leaving the sclera exposed
o Higher risk of recurrence
2. Conjunctival Autograft Technique (Preferred Method):
o After removing the pterygium, healthy conjunctival tissue from the patient’s own eye is grafted to the affected area
o Significantly reduces the chance of recurrence
3. Amniotic Membrane Grafting:
o Used when autograft is not possible
o Anti-inflammatory and promotes healing
Recovery and Aftercare
Postoperative recovery is usually quick, with most patients resuming normal activities within a week.
Aftercare tips:
· Use prescribed antibiotic and anti-inflammatory eye drops
· Wear sunglasses to protect from UV rays
· Avoid dusty or windy environments during healing
· Attend follow-up visits to monitor for recurrence
Some redness and mild discomfort are normal for a few days after surgery.
Risks and Complications
Pterygium surgery is generally safe, but possible complications include:
· Recurrence (more likely with bare sclera technique)
· Infection
· Scarring
· Graft displacement
· Rarely, damage to the cornea
