Abstract

Purpose: To compare retinal nerve fiber layer (RNFL) thickness measurements by 2 Fourier-domain optical coherence tomography (OCT) instruments: Cirrus-HD OCT and RTVue. Materials And Methods: Twenty-three eyes of 23 healthy participants underwent RNFL thickness measurement using both devices on the same day. The NMH4 and Optic Disk Cube 200×200 protocols were used, respectively, for scan acquisition with RTVue and Cirrus-HD OCT. Measurements were compared by means of a paired t test. Results: RTVue gave higher mean RNFL thickness values than Cirrus-HD OCT in the superior (128.44±22.48 vs. 119.73±18.22μ, P=0.0002), inferior (137.15±21.99 vs. 124.94±22.51μ, P
