Emerging Applications of Optical Coherence Tomography in Pediatric Optic Neuropathies.
Limited cooperation and attention span often lead to poorly reliable assessments of visual acuity and visual fields in children, making diagnosis and monitoring of pediatric optic neuropathies challenging. As a noninvasive imaging modality, optical coherence tomography (OCT) could offer particular utility in this patient population. OCT provides high-resolution characterization of the optic nerve head, peripapillary retinal nerve fiber layer, and cellular layers of the macula, all of which can be used to assess the severity of optic nerve disease qualitatively and quantitatively. Application of OCT to pediatric patients has been limited by technical factors and lack of pediatric normative databases, but with recent technological improvements and rapidly expanding research efforts OCT is poised to revolutionize the management of optic neuropathies in children. We review current and emerging applications of OCT to important pediatric optic neuropathies such as glaucoma, papilledema, optic neuritis, optic pathway gliomas, and congenital optic disc anomalies.
