Retinal nerve fiber layer and optic disc measurements by spectral domain OCT: normative values and associations in young adults
Purpose To determine normative values and associations of retinal nerve fiber layer (RNFL) and optic disc parameters in normal eyes measured by spectral domain optical coherence tomography (OCT). Methods In a population-based setting, 1521 young adults were examined as part of the Sydney Adolescent Vascular and Eye Study (SAVES). Their mean age was 17.3±0.6 years. RNFL and optic disc parameter measurements were made using Cirrus HD-OCT 4000. Results The average RNFL was found to be 99.4±9.6 μ m. RNFL thickness was least for the temporal quadrant (69.9±11.2 μ m), followed by the nasal ...
