Summary
Evaluation of effect of various OCT scan speeds and filters on parameter measurements.
Detailed description
The objectives of this study are to 1. Directly compare parameter measurements generated on scans acquired at different speed modes with various levels of signal-to-noise ratio (SNR). 2. Evaluate the effects of SNR, as determined by the device's Q score, on parameters derived from segmentation results, i.e., thickness of peripapillary retinal nerve fiber layer on circle scans (pRNFL), minimum rim width of optical nerve head (MRW), and macular layer thicknesses (Retina, GCL, IPL).
