What is a pterygium?
A pterygium is a common, usually non-cancerous growth of tissue on the white part of the eye that can slowly extend onto the clear front surface of the eye (the cornea). It is often associated with long-term exposure to sunlight, wind, and dust, and may cause redness, irritation, dryness, or blurred vision as it enlarges. In some cases, growths on the eye surface can show pre-cancerous or cancerous changes, known as ocular surface squamous cell neoplasia (OSSN), which is why suspicious, atypical, or rapidly growing lesions should be assessed promptly by an eye specialist.

What are the signs and symptoms of a pterygium?
Common symptoms of a pterygium include redness, irritation, dryness, or a gritty sensation in the affected eye. Patients often notice a visible, fleshy growth on the white part of the eye that can slowly extend toward the coloured part of the eye and may appear cosmetically noticeable or aesthetically displeasing. As it enlarges, a pterygium can cause blurred or distorted vision and increased sensitivity to light, particularly in bright, windy, or dusty environments.

What is the treatment for pterygium?
Treatment for a pterygium depends on its size, symptoms, and effect on vision. Mild cases may be managed with lubricating eye drops or anti-inflammatory treatment to reduce irritation and redness. If the pterygium continues to grow, affects vision, causes significant discomfort, or is cosmetically concerning, surgical removal may be recommended, often with techniques designed to reduce the risk of recurrence and promote smooth healing.
