Retinal Nerve Fiber Layer Imaging with Spectral-Domain Optical Coherence Tomography: A Study on Diagnostic Agreement with Heidelberg Retinal Tomograph
Objective
To evaluate and compare the diagnostic agreement and performance for glaucoma detection between a confocal scanning laser ophthalmoscope and a spectral-domain optical coherence tomograph (OCT).
Design
Prospective, cross-sectional study.
Participants
One hundred fifty-five subjects (79 glaucoma and 76 normal subjects).
Methods
One eye from each individual was selected randomly for optic disc and retinal nerve fiber layer (RNFL) imaging by the Heidelberg Retinal Tomograph (HRT; Heidelberg Engineering, GmbH, Dossenheim, Germany) and the Spectralis OCT (Heidelberg Engineering), respectively. Glaucoma was defined based on the presence of visual field defects with the Humphrey visual field analyzer (Carl Zeiss Meditec, Dublin, CA ...
