What is Pterygium ??
A pterygium is a benign (non-cancerous) growth of the conjunctiva — the thin, transparent tissue covering the white part of the eye (sclera) — that extends onto the cornea.
It’s often shaped like a wedge or a wing, starting from the inner (nasal) side of the eye and growing toward the pupil.

⭐ Key Features
Location: Commonly on the nasal side of the eye, but can occur on the temporal side too.
Appearance: A fleshy, triangular or wing-shaped growth.
Progression: It may stay small or slowly grow across the cornea and affect vision.
---------
🧐 Causes / Risk Factors
Chronic exposure to ultraviolet (UV) light (sunlight).
Dust, wind, smoke, or dry environments.
More common in people who live in hot, sunny climates (e.g., “surfer’s eye”).

🛑 Symptoms :-
Redness
Irritation or foreign-body sensation
Dryness
Blurred vision if it encroaches on the cornea

✅ Treatment :-
Conservative: Lubricating eye drops, sunglasses to reduce UV exposure, avoiding dust/wind.
Surgical removal: Indicated if it causes significant discomfort, restricts eye movement, or threatens/affects vision by covering the pupil or inducing astigmatism.
