Clinical applications of optical coherence tomography in optic nerve disease

Optical coherence tomography (OCT) is a relatively new technology that provides information about the retina, optic nerve, and nerve fiber layer (NFL) differently from other instruments.¹ Newer versions of the OCT allow better resolution, which makes it useful for management of optic nerve disease. For neuro-ophthalmology, OCT methods employed for retinal as well as glaucoma analysis are used, because some optic nerve pathologies have macular complications, but also because many retinal conditions may mimic optic nerve disease.
