Abstract

PURPOSE: To evaluate and compare the detection of incomplete and complete retinal pigment epithelial and outer retinal atrophy (iRORA and cRORA) using Spectralis and Cirrus optical coherence tomography (OCT) devices. METHODS: Subjects with late age-related macular degeneration were imaged on the same day with Spectralis and Cirrus OCT. Two, masked, independent, and experienced retina specialist graders evaluated each case for the presence of cRORA and iRORA lesions. RESULTS: A significantly higher number of lesions were observed using Spectralis compared with Cirrus (239 vs. 226 and 223 vs. 209). Higher number of iRORA lesions were identified with Spectralis (105 vs. 90 and 96 vs. 82), and no significant difference was observed between devices for cRORA lesions (134 vs. 136 and 128 vs. 126). When considering the presence or absence of iRORA or cRORA, the agreement between devices for both graders was excellent for cRORA and good for iRORA. CONCLUSION: Spectralis and Cirrus OCT identified a similar number of cRORA lesions, although more iRORA lesions could be detected with Spectralis OCT. These findings may have implications for developing acquisition protocols for trials based on the intended atrophy targets and highlight the importance of using a consistent OCT instrument across a study.
