Figure 2From: The influence of corneal astigmatism on retinal nerve fiber layer thickness and optic nerve head parameter measurements by spectral-domain optical coherence tomographyRNFL profiles of normal astigmatism group (n = 34) and high CA group (n = 36). Significant differences were found at 2 o’clock, 9 o’clock, and 10 o’clock, * indicates P < 0.05; ** P < 0.01.Back to article page
