Table 5. Comparison of sensitivity and specificity of RNFL photographic assessment and GC-IPL parameters to detect central VF progression (n = 274).

RNFL = retinal nerve fiber layer; GC-IPL = ganglion cell inner plexiform layer; VF = visual field.

^*Test-retest variability defined at the 80% confidence level, shown with the 95% confidence interval in parentheses; ^†Statistically significant (McNemar's test).
