Corneal Subepithelial Nodular Scarring Treated with Phototherapeutic Keratectomy in a Child with Rothmund–Thomson Syndrome

PURPOSE: To report the use of excimer laser phototherapeutic keratectomy (PTK) in the treatment of corneal subepithelial nodular scarring in a child with Rothmund-Thomson syndrome (RTS), a form of ectodermal dysplasia. METHODS: A case report and review of the literature. RESULTS: Excimer laser PTK successfully treated the recurrent anterior stromal fibrosis and irregular astigmatism, facilitating visual development. The use of excimer laser PTK prevented the development of dense amblyopia in this child. CONCLUSION: This case demonstrates an indication for excimer laser PTK in the pediatric population.
