Objective: To describe the main uses of angiography by optical coherence tomography (OCT-A) in glaucoma, its main characteristics and potential uses as a diagnostic tool described in the literature. Study design: Literature reviewMethods: Review of medical literature using PubMed and Scopus between 2013 and 2017.Conclusions: Changes at papillary, peripapillary and macular capillary levels may lead to a more accurate and even an early diagnosis of glaucoma, leading us to think about possible earlier findings in the OCT-A compared to classical changes in the visual field and optical coherence tomography (retinal nerve fiber layer).Additionally, its potential use in the detection of progression should be evaluated, allowing a better monitoring of the disease.
