Detection, aetiology and management of conjunctival intraepithelial neoplasia

Conjunctival intraepithelial neoplasia (CIN) are considered to be the third most common ocular tumour and the most common tumour of the ocular surface. Due to their malignant potential, they must be carefully differentially and promptly treated. A recurrence rate of approximately 30% leads to the need for monitoring of patients even after successful treatment. This article presents several cases of CIN and reviews their histopathology, aetiology, appearance, differential diagnosis and management. Typical patient presentations and prognoses are also discussed. (C) 2000 The College of Optometrists. Published by Elsevier Science Ltd. All rights reserved.
