HD-OCT thickness maps best confirm RNFL defects in eyes with early glaucoma
Thickness maps generated with high-definition spectral-domain optical coherence tomography proved more useful than other maps in identifying retinal nerve fiber layer defects in glaucomatous eyes, according to a study.Investigators evaluated the accuracy of clock-hour, deviation and thickness maps created with the Cirrus HD-OCT (Carl Zeiss Meditec) in detecting retinal nerve fiber layer (RNFL) defects previously identified in red-free fundus photographs.
