Congenital inner eyelid folds

Background: We describe the ocular findings in two infants who were found to have unusual internal eyelid folds during routine probing for nasolacrimal duct (NLD) obstruction. Materials and methods: Medical records review of two patients with similar eyelid folds. Results: Both children had unusual eyelid folds that began on the inner eyelid adjacent to the lacrimal canaliculi and extended to a position near the caruncle. Both children had resolution of NLDO following routine surgery, suggesting that the eyelid anomalies were an incidental finding at the time of NLDO surgery. Conclusion: The etiology of these unusual inner eyelid folds is not certain but may represent schisis or incomplete separation of the inner eyelid margin.
