Research progress of the spectral-domain optical coherence tomography for glaucoma diagnosis

Optical coherence tomography (OCT) has the advantage of non-contact, good repeatability and quick to obtain retinal image.With the rapid development of resolution and scanning speed, OCT has been more widely used in the field of ophthalmology.OCT has developed from time-domain OCT (TD-OCT) to spectral-domain OCT(SD-OCT). OCT can diagnose glaucoma without visual field damage and play an important role in monitoring and diagnosing the progression of primary open angle glaucoma.In recent years, SD-OCT has made an enoumous contribution to the detection and diagnosis of glaucoma, by detecting retinal nerve fiber layer (RNFL) thickness, structural parameters of optic disc as well as the macular ganglion cell complex (mGCC) thickness.This paper reviewed the relevant researches of the three parameters obtained from SD-OCT on the diagnosis of primary glaucoma.
