Comparison of Spectralis and Cirrus optical coherence tomography for the detection of incomplete and complete retinal pigment epithelium and outer retinal atrophy

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 (AMD) 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 ...
