Dr. Dexter's Take

Due to its constant exposure to UV radiation and atmospheric irritants, the interpalpebral space of the conjunctiva often develops irregular tissue changes that are, for the most part, non-pathologic. However; not all lesions that present in this area can be considered simply a pinguecula or pterygium. It is important to look for subtle irregularities that may steer you in the direction of a more serious lesion, such as conjunctival intraepithelial neoplasm (CIN) or squamous cell carcinoma. Diagnosis of these conditions can be difficult; therefore, this article presents a great opportunity to review the clinical signs to be aware of for those who may not see these on a regular basis.
