Misalignments in the Retinal Nerve Fiber Layer Evaluation Using Cirrus High-definition Optical Coherence Tomography

Abstract

CMAs were present in the first or second scans in about 30% of cases and were related to older age. CMAs were more frequently in horizontal meridians and quadrants. No differences in RNFL thickness were found between scans with and without CMAs in the same patients. Scans with CMAs in the measurement ring can be considered in the RNFL evaluation.
