Table 1.

Comparison between treated eyes and fellow eyes. Baseline characteristics of all enrolled patients and IOP measurements at different times for eyes receiving drops and fellow eyes. p values for IOP differences between the two groups and between eyes receiving the drop and fellow eye are also reported
