Retinal Nerve Fiber Layer Imaging with Spectral-domain Optical Coherence Tomography: Patterns of Retinal Nerve Fiber Layer Progression
Objective To examine the use of the retinal nerve fiber layer (RNFL) thickness map generated by a spectral-domain optical coherence tomography (OCT) to detect RNFL progression and identify the pattern of progressive changes of RNFL defects in glaucoma. Design Prospective, longitudinal study. Participants One hundred eighty-six eyes of 103 glaucoma patients. Methods Patients were followed at 4-month intervals for ≥36 months for RNFL imaging and visual field examination. Both eyes were imaged by the Cirrus HD-OCT (Carl Zeiss Meditec Inc., Dublin, CA) and had visual field testing at the same visits. We defined RNFL progression by Guided Progression Analysis (Carl ...
