TABLE 5.

Median Time to Glaucoma Progression for the Subgroup of Patients who Progressed According to the Event-based Criterion for Each Modality using Kaplan-Meier Survival Analysis.

Modality	Median time to event-based progression (months; 95%CI)
Disc photograph	44 (36, 55)
Visual field	32 (27, 41)
2D RNFL thickness
Global overall	33 (31, -)^†
3D neuroretinal rim thickness
Global overall	23 (17, 32)

CI indicates confidence interval; 2D, two-dimensional; 3D, three-dimensional; RNFL, retinal nerve fiber layer.

^†

indicates that the number of eyes meeting the progression criteria for this modality was too low to compute the upper limit of the 95% CI.
