Correlation Between Peripapillary Retinal Nerve Fiber Layer Thickness and Optic Nerve Head Parameters Using Spectral Domain Optical Coherence Tomography

AIMTo evaluate correlation between peripapillary retinal nerve fiber layer thickness (RNFL) and optic nerve head (ONH) parameters in normal participants using Spectral domain optical coherence tomography (OCT). METHODSSixty-five eyes of 65 healthy participants aged 13–79 years underwent ONH analysis and peripapillary RNFL thickness measurements using spectral domain OCT. The RNFL measurements were correlated with the data obtained with ONH analysis. RESULTSThe average and quadrant RNFL thickness did not show correlation with optic disc area. A positive correlation was found between average RNFL thickness and rim area (r=0.425, P=0.000) and negative correlation between average RNFL thickness and cup area (r=−0.249, P
