Foveal Avascular Zone in Normal Tension Glaucoma Measured by Optical Coherence Tomography Angiography

Table 4

Interobserver reliability.

	NTG group; ICC (95% CI)	Control group; ICC (95% CI)
Vertical diameter	0.996; (0.991–0.999)	0.994; (0.990–0.997)
Horizontal diameter	0.989; (0.974–0.995)	0.994; (0.988–0.996)
Maximum diameter	0.996; (0.991–0.998)	0.996; (0.992–0.998)

NTG = normal tension glaucoma, ICC = intraclass correlation coefficient, and 95% CI = 95% confidence interval.
