Using Spectral-domain-optical coherence tomography (SD-OCT), we have studied the behaviour of the laminar region in 14 young subjects over 24h. Significant changes in LCT were observed, depending on the time at which the measurement was taken, with the maximum thickness being observed at 7.30 p.m., and the minimum at 7.30 a.m. This finding could suggests a circadian pattern in the LCT thickness in healthy subjects, which could have implications for the classification, diagnosis and prognosis of both normal and glaucomatous subjects.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/glaucomalamina cribrosalaminar regionoptical coherence tomographytwenty-four-hoursresearch article28251093open access10.18240/ijo.2017.02.20PMC5313557https://doi.org/10.18240/ijo.2017.02.20https://pmc.ncbi.nlm.nih.gov/articles/PMC5313557/pdf
