Pterygium

Overview

Pterygium is a triangular fibrovascular overgrowth of the bulbar conjunctiva that can extend onto the corneal surface. Patients usually have no symptoms or slight foreign body sensation and may have eye redness; if it grows onto the cornea it can cause astigmatism and affect vision, and involvement of the pupil area can significantly reduce vision.

Symptoms

• Conjunctival overgrowth
• Triangular invasion of the cornea
• Redness
• Foreign body sensation
• Affects vision

Treatment

Often related to UV exposure. Observe and follow up mild cases; surgical excision is an option when vision or appearance is affected.

Dietary advice

Eat a light diet with plenty of vitamin-rich fruits and vegetables, and protect against UV rays outdoors.
