Despite the importance of the iridocorneal angle in childhood glaucoma, relatively few studies have been published on the outflow system in children and how surgery affects the iridocorneal angle. Using overhead-mounted optical coherence tomography, we investigated the iridocorneal angle of patients with childhood glaucoma after angle surgery to describe the appearance of the angle and how it may be associated with intraocular pressure (IOP) control. No eyes showed closed angle or peripheral anterior synechiae. Almost all imaged eyes (89%) had a visible open cleft, but many had inadequately controlled IOP. The presence of a cleft, residual trabecular meshwork or remnant of tissue, and open collector channels were not associated with IOP at the time of imaging, although our analysis did not control for other treatment variables that may have masked associations of IOP with anatomical features.
