Pterygium

A pterygium — sometimes called 'surfer's eye' — is a fleshy, wing-shaped growth on the white of the eye that can slowly extend onto the cornea. Common in New Zealand's outdoor, high-UV climate, it's usually harmless but can grow, redden, and occasionally affect vision.

What it is

A pterygium grows from the conjunctiva — the clear surface over the white of the eye — usually on the side nearest the nose. It's strongly linked to a lifetime of sun, wind and dust exposure.

Most grow very slowly and cause few problems, but a larger one can become red and irritated, or extend far enough onto the cornea to blur vision or pull it out of shape.

What you might notice

A fleshy, pinkish growth on the white of the eye
Redness or irritation, especially in wind or sun
A gritty, foreign-body feeling
Occasionally, blurred vision if it reaches the cornea

Recognise these? Book a consultation and we'll help you get to the bottom of it.

What causes it

Long-term exposure to UV light, wind and dust — which is why it's often called 'surfer's eye' and is common in sunny, outdoor places like New Zealand.

It's more common with age and in people who spend a lot of time outdoors.

How we help

A small, quiet pterygium usually just needs monitoring, sun protection and lubricating drops for comfort. Dr Leong can assess how far it's advanced and whether it's affecting your vision.

If a pterygium is growing, persistently inflamed, or threatening your sight, it can be surgically removed — and we'll talk you through what that involves.

Common questions

Is a pterygium dangerous?

It's usually harmless — not a cancer — but it's worth having checked to confirm the diagnosis and to keep an eye on whether it's growing towards the cornea.

Does a pterygium need to be removed?

Not always. Many just need sun protection and lubricating drops. Removal is considered if it's growing onto the cornea, affecting vision, or persistently red and uncomfortable.

Can a pterygium come back after removal?

It can, which is why the surgical technique matters. Dr Leong can talk you through the approach used to reduce that risk.

How do I stop a pterygium getting worse?

Protect your eyes from UV — good wraparound sunglasses and a hat outdoors — and keep the surface comfortable with lubricating drops. That's the best way to slow it.
