A conjunctival naevus is a benign pigmented lesion (eye freckle) on the surface of the eye. It is usually present from childhood and often remains stable for many years.
Appearance and Behaviour
Naevus lesions may be flat or slightly raised and can contain small clear cysts on close examination. Colour and size are typically stable, though mild changes can occur over time.
- Most are harmless and monitored with periodic photographs
- Any rapid change in size, colour, or shape warrants review
- Rarely, conjunctival melanoma can arise, so vigilance is important
Management
Observation is appropriate for typical, stable naevi. Excision may be considered if there is diagnostic uncertainty, growth, or cosmetic concern; see the conjunctival naevus removal information and related Blue Fin Vision® resources.
Pathology
Removed lesions are usually sent for histological analysis to confirm the diagnosis.
