FERNANDEZ ARGONES, Liamet et al. Detection of Glaucoma Using Optical Coherence Tomography. Rev Cubana Oftalmol [online]. 2023, vol.36, n.2  Epub June 01, 2023. ISSN 1561-3070.

Optical coherence tomography has become the most common imaging system for early detection of glaucomatous damage; hence, it is essential for clinical decisions and as a criterion for inclusion in research and clinical trials. The objective is to present the advances in the application of optical coherence tomography in the detection of glaucoma by reviewing the publications of the last five years. The search was performed in Google Scholar using keywords. Improvements in spectral domain and scanning source technology have allowed the segmentation of ganglion cells, the recognition of Bruch's membrane aperture as a reference point for the analysis of optic disc parameters and the development of non-contrast angiography. For the diagnosis of glaucoma, the structure was analyzed in three locations (macular ganglion cells, peripapillary neuroretinal fiber layer, neuroretinal ring and optic disc cup) and the superficial vascular plexus in two (parafoveal and peripapillary). It is recommended to check quality and presence of artifacts prior to the analysis of the results; as well as to complement these results with the interrogation and findings on ophthalmologic examination, mainly by posterior pole biomicroscopy, to minimize the possibility of diagnostic errors. It is useful to keep this in mind, despite the large number of patients that come to the glaucoma clinic every day. Advantages and limitations of structural and vascular parameters in the diagnosis of glaucoma are pointed out.

Keywords : glaucoma; OCT; OCTA; OCT angiography; ganglion cells-internal plexiform; neuroretinal fiber layer.
