Congenital ciliary body cysts causing lens abnormalities and secondary angle closure glaucoma in a child

PURPOSE: To report a case of congenital ciliary body cysts causing microspherophakia, ectopia lentis, and secondary angle closure glaucoma in an infant. OBSERVATIONS: A 16-month-old male was found to have bilateral ciliary body cysts associated with zonular laxity or absence causing microspherophakia and ectopia lentis as demonstrated on multimodal imaging. Additionally, the patient had secondary angle closure glaucoma which was likely multi-factorial related to both lens abnormalities and anterior displacement of the iris from the cysts themselves. The patient underwent lensectomy and cyst removal which resulted in intraocular pressure stabilization and visual rehabilitation. CONCLUSIONS AND IMPORTANCE: Congenital ciliary body cysts are a rare cause of lens abnormalities and secondary angle closure glaucoma in children. Information regarding genetic underpinnings or systemic associations is limited.
