A conjunctival naevus is a small, pigmented lesion on the white surface of the eye. It is usually present from childhood or early adult life and is typically benign.
Typical features
These naevi often change slightly with age, especially around puberty. Careful documentation helps distinguish normal variation from worrying growth.
- They may appear light or dark brown and can contain tiny clear cysts.
- Most are flat or only mildly raised.
- They are commonly located near the coloured part of the eye.
- Symptoms are rare, though some people notice mild irritation.
- Photographs provide a useful baseline for future comparison.
Monitoring and treatment
Most conjunctival naevi simply require periodic review. Intervention is considered if the lesion grows, changes, or causes irritation.
- Rapid enlargement, increased thickness, or bleeding warrant urgent assessment.
- Suspicious lesions may be removed and examined in the laboratory.
- Simple excision is usually quick and carried out under local anaesthetic.
- Regular follow-up reassures patients and detects any early change.
- Report any new symptoms such as pain or persistent redness.
