Intraocular pressure (IOP), mitomycin C (MMC), and millimeters of mercury (mmHg).

^∗MMC 0.4 mg/mL for 3 minutes.

^∗∗The authors did not report values of success rate; they reported P values obtained by Fisher exact test for categorical variables and survival analysis to access the success rate through time. No significant difference on the failure time of the procedure, for both success IOP values considered, was observed between the groups (P = 0.746 for IOP <21 mmHg and P = 0.216 for IOP ≤15 mmHg).
