Vitrectomy for Tractional Retinal Detachment Due to Combined Hamartoma of the Retina and Retinal Pigment Epithelium

Purpose: We discuss a peripheral combined hamartoma of the retina and retinal pigment epithelium (CHRRPE) with a macula-involving TRD that was repaired by vitrectomy surgery. Methods: A case report is presented. Results: A 15-year-old white girl with no significant medical or ocular history presented to the retina clinic with a 1-month history of progressive loss of inferior visual field in the right eye. A large, elevated CHRRPE was found in the superior midperipheral retina. On involvement of the macula, urgent vitrectomy surgery with peeling of the cortical vitreous membrane to the margins of the hamartoma was performed. Eighteen months later, vision had returned to 20/16 and the retina, relieved of traction, continued to reattach with trace remaining cystic changes at the fovea on optical coherence tomography. Conclusions: Physicians should consider vitrectomy surgery with membrane peeling of the cortical vitreous for TRD due to CHRRPE.
