The clinicopathological characteristics of 343 naevi of the conjunctiva were studied. A significant increase in the number of naevi excised per annum was observed. This may have been caused by an increased exposure to actinic rays. Approximately even distribution in the three main locations: caruncle, limbal area and eyeball, was found. Intrastromal naevi were excised at a higher median age than compound naevi, and the lowest observed median age at excision was for junction naevi, which is in accordance with the known histopathological nature of naevi. Recurrence occurred in nine patients (2.7%), and one transformed to a malignant melanoma. Eight of the recurring naevi were located in the limbal area. Eight of the nine patients were women, suggesting hormonal factors as a possible cause. Recommendations for the handling of conjunctival naevi are given, based on the present findings and on previous reports.
