The authors present a case of absent multiple extraocular muscle insertions in Pfeiffer syndrome. An 8-year-old girl with Pfeiffer syndrome presented with V-pattern exotropia and left hypertropia. The absence of bilateral superior oblique, bilateral superior rectus, and left inferior rectus muscle insertions was found intraoperatively. [J Pediatr Ophthalmol Strabismus. 2022;59(2):e17-e19.].
