1. Aim: To report the frequency and severity of retinal thickness measurement errors in a Fourier domain optical coherence tomography (FDOCT) device, Cirrus OCT. Methods: Data from 209 eyes undergoing Cirrus OCT imaging with the Macular Cube protocol were collected. For each eye, the position of the automated retinal boundary lines used by the Cirrus OCT software for thickness calculations was assessed using a 6-point categorical scale. The presence of errors was correlated with various parameters including: retinal morphologic features and disease diagnosis. Results: Errors of retinal boundary detection were observed in 57.5% of eyes, but were severe in ... (Read Full Article)
