Better best-corrected visual acuity values and baseline thicker ganglion cell layer and retinal nerve fiber layer at ocular coherence tomography measurements were found to be the key predictive factors.
The investigators described the CASIA2 (Tomey Corporation) instrument, which is a new AS-OCT device with a swept-source laser wavelength of 1310 nm that can scan at a speed of 50,000 A-scan/second.
