[Pay attention on optical coherence tomography evaluation for optic nerve diseases].

Optical coherence tomography(OCT) had become the most important imaging technique in ophthalmology. OCT is able to segment the retinal nerve fiber layer and retinal ganglion cell layer accurately. Quantitative analysis can be performed for both layers. OCT is very important to evaluate the neuron and axon loss in optic nerve diseases diagnosis. Meanwhile, OCT has great value for differentiating glaucoma and macular diseases from optic nerve diseases. This review presented OCT application in optic nerve diseases diagnosis, differentiation diagnosis, the key points in use and the features of en face OCT and OCT angiography. It gave us suggestions that it should be pay more attention to OCT examination in diagnosis and treatment of optic nerve diseases. (Chin J Ophthalmol, 2016, 52: 885-888).
