Pterygium Treatment & Conjunctival Autograft Surgery
Understanding Pterygium ("Surfer's Eye") & Corneal Health
A pterygium is a benign, triangular or wing-shaped growth of fibrovascular tissue that originates on the white of the eye (the bulbar conjunctiva) and slowly advances across the limbus onto the clear dome of the eye (the cornea). While non-cancerous, an enlarging pterygium can cause chronic foreign-body sensation, persistent redness, dry eye aggravation, and induce astigmatism that impairs your vision.
At My Vision Eye Clinic on Sarjapur Main Road, Dr. Rinku Das (MBBS, MS Ophthalmology, FIAS, FIG) provides comprehensive clinical evaluation and advanced surgical management using the gold-standard conjunctival autografting technique. Serving patients from Kaikondrahalli, Bellandur, Haralur, Kasavanahalli, and across Bengaluru, our clinic focuses on restoring ocular comfort and clear sight while effectively minimizing recurrence.
What Triggers Pterygium & How Is It Evaluated?
Pterygium development is closely tied to chronic environmental irritation. Key contributing factors include:
- Ultraviolet (UV) Radiation: Sunlight exposure damages limbal stem cells, triggering abnormal fibrovascular tissue proliferation.
- Dust and Wind: Regular two-wheeler commuters navigating Bengaluru traffic without protective eyewear experience repeated micro-trauma to the ocular surface.
- Chronic Dry Eye Syndrome: Poor tear film lubrication prevents the ocular surface from clearing irritants, fueling localized inflammation.
Clinical Staging of Pterygium
| Stage | Clinical Presentation | Management Approach |
|---|---|---|
| Stage 1 (Pinguecula / Early Pterygium) | Small yellowish nodule or minimal growth limited to the conjunctival border without crossing the limbus. Mild redness. | Conservative medical management: lubricating artificial tears, UV400 sunglasses, periodic monitoring. |
| Stage 2 (Progressive Pterygium) | Growth encroaches 1 to 2 mm onto the peripheral cornea. Persistent foreign body sensation, burning, and visible vascularization. | Anti-inflammatory topical drops, close observation of growth progression towards the optical axis. |
| Stage 3 (Advanced / Obstructive) | Tissue extends toward or covers the visual pupillary axis, pulling on the cornea and inducing significant astigmatism or vision loss. | Surgical excision with conjunctival autograft (CAG) to restore corneal curvature and visual axis. |
Clinical Treatment Approaches: Conservative vs. Surgical
1. Conservative Medical Management
For early or non-progressive pterygia, surgery is not immediately required. Dr. Rinku Das prescribes preservative-free lubricating eye drops to soothe ocular surface friction, short courses of mild topical anti-inflammatory drops during acute flare-ups, and emphasizes UV-blocking wraparound sunglasses for outdoor commuting.
2. Surgical Excision with Conjunctival Autograft (CAG)
When pterygium grows towards the pupillary axis, causes recurrent severe inflammation, or distorts vision, surgical removal is necessary. At My Vision Eye Clinic, we prioritize the conjunctival autografting method:
- Careful Microsurgical Excision: The abnormal fibrovascular pterygium tissue is delicately peeled away from the cornea and underlying sclera under high-magnification surgical visualization.
- Harvesting Autograft Tissue: A small, thin graft of healthy conjunctival tissue containing limbal stem cells is harvested from beneath the patient's own upper eyelid (superior bulbar conjunctiva).
- Securing the Graft: The graft is transplanted over the exposed surgical bed and secured with micro-sutures or fibrin tissue glue. This biological barrier dramatically reduces recurrence compared to older excision techniques.
What to Expect: Day-Care Procedure & Recovery
Performed under local numbing eye drops. The surgical procedure typically takes 30 to 45 minutes, with no overnight hospital stay required.
A temporary scratchy feeling, redness, and mild watering are completely normal for 2 to 3 days as the surface epithelium heals over the graft.
Patients receive protective eyewear and medicated antibiotic-steroid eye drops. Normal non-strenuous desk activities can be resumed in 2 to 4 days.
