IntroductIonGlaucoma is defined as a chronic, progressive, usually bilateral, and asymmetric optic neuropathy with specific changes in the optic nerve head (ONH), the retinal nerve fiber layer (RNFL), and the visual field. 1 The underlying pathophysiological process is the loss of retinal ganglion cells (RGC). 2 Usually, by the time a glaucomatous visual defect is detected, approximately 28% of the RGC and 17% of the RNFL thickness have been irreversibly damaged. 3,4s our understanding of glaucoma has evolved, so has the technology.Optical coherence tomography (OCT) has continued to add parameters to aid in the detection and management of glaucoma.Currently, the peripapillary RNFL is a very important measure for the clinical diagnosis of this entity. 5,6[9][10] A new generation of OCT, the swept-source OCT (SS-OCT), was recently introduced.SS-OCT uses a longer wavelength (usually 1050 nm) compared to spectral-domain OCT (SD-OCT).This not only enables the evaluation of RNFL and macular thickness but also allows for high-grade imaging of deeper ocular structures.Additionally, SS-OCT has the advantage of faster scanning speeds (100.000-200.000A-scans/second), which allows the capture of larger areas in less time.
