Influence of cataract in reproducibility of Optical Coherence Tomography measurements

Purpose To evaluate the effect of lens opacities in quality of images and reproducibility of retinal nerve fiber layer (RNFL) thickness measurements using Spectralis Optical Coherence Tomography (OCT). Methods Fifty eyes of 50 subjects (25 men and 25 women; aged from 62 to 88 years) underwent three...

Description
Summary:Purpose To evaluate the effect of lens opacities in quality of images and reproducibility of retinal nerve fiber layer (RNFL) thickness measurements using Spectralis Optical Coherence Tomography (OCT). Methods Fifty eyes of 50 subjects (25 men and 25 women; aged from 62 to 88 years) underwent three 360° circular scans centred on the optic disc by the same experienced examiner using the “RNFL Fast” Glaucoma Application and the “RNFL‐N Fast” Axonal Application of Spectralis OCT instrument one month before and one month after cataract surgery. Comparison between the two visits and changes in reproducibility (using intra‐class correlation coefficients and coefficients of variation) were analyzed. The quality of images was also compared between both visits. Results RNFL and RNFL‐N differences were detected between both visits for average thickness, temporal and nasal quadrants (p
