Many eye disease cause abnormalities in the retina and optic nerve head (ONH), direct cross-sectional imaging could improve the early diagnosis and provide a more sensitive monitoring of a variety of retinal and ONH disease. The introduction of optical coherence tomography into clinical practice in 1996 made it possible to routinely measure retinal thickness in a non-contact and non-invasive manner. This analysis document the normal distribution of macular, retinal nerve fiber layer thickness and optic disc parameters, as measured using OCT in a population-based sample of young persons and to...
