Clinical Trial Summary

This study is a prospective comparative, randomized, single center study to gather agreement and precision of the Nidek Mirante OCT with SLO and Anterior Segment Imaging capabilities in comparison to the Optovue RTVue XR Avanti OCT and Optos P200DTx in normal subjects, subjects with glaucoma, subjects with retinal disease and subjects with corneal disease.

Description:

This is a prospective comparative clinical study to be conducted at one clinical site located in the United States. Three Nidek Mirante devices, three Optovue RTVue XR Avanti devices and one OPTOS P200DTx will be used. For agreement and precision analysis of OCT scans and agreement analysis of image quality of OCT ACA scans, each Nidek Mirante device will be paired with one of the Optovue RTVue XR Avanti devices. One device operator will be assigned to each device pair to create three distinct operator/device configurations.

For agreement analysis of SLO image quality, one OPTOS P200DTx will be included in one of three operator/device configurations.
