Congenital ectropion uveae (CEU) is a rare anomaly of the embryonic development of the anterior segment of the eye. We report the case of a 5-year-old child with an undiagnosed CEU who was treated urgently for an acute angle closure attack. CASE DESCRIPTION: A 5-year-old child was referred urgently for evaluation of anisocoria with mydriasis of the right eye and severe headache. Brain imaging with contrast injection was initially performed in the pediatric emergency department and ruled out central nervous system pathology. The initial examination of the right eye revealed an intraocular pressure (IOP) of 37mmHg, corneal edema, congenital ectropion uveae, mydriasis with pupillary block, a closed angle on gonioscopy, and a clear lens. The examination of the left eye was unremarkable, with no visible CEU. The initial management consisted of medical treatment with topical glaucoma drops and miotics and acetazolamide at 10mg/kg/d. Re-evaluation under general anesthesia showed persistent mydriasis and no resolution of the pupillary block. Filtering surgery was performed in the absence of a complete response to medical treatment, allowing control of IOP without drops and complete regression of the corneal edema. DISCUSSION: CEU is a rare malformation, and pressure complications represent an insignificant proportion of pediatric glaucoma cases. The acute presentation of acute angle closure in this potentially blinding short-term setting, however, makes detection and management difficult in very young children in a great deal of pain. Only one similar case has been reported in the pediatric literature. CONCLUSION: Acute angle closure complicating CEU is exceptional and difficult to diagnose in a pediatric context. Parents of children with this predisposing condition should be informed of the need to consult urgently when clinical signs of elevated intraocular pressure appear.
