Optical coherence tomography in the setting of optic nerve head cupping reversal in secondary childhood glaucoma.

Reversal of optic nerve head (ONH) cupping has been considered an important clinical observation that signals surgical success and control of intraocular pressure (IOP) in childhood glaucoma. Many theories based on elasticity of pediatric eyes have been proposed, including anterior movement of the elastic lamina cribrosa or shrinkage of the scleral canal. The relationship between these factors and axonal loss is unclear when reversal of cupping has been observed. Retinal nerve fiber layer (RNFL) optical coherence tomography (OCT) can help to clarify this. We present a case series of 4 pediatric patients with secondary glaucoma that demonstrated ONH cupping reversal with pre- and postoperative clinical images and RNFL OCT.
