Fig. 2From: Collagen matrix vs mitomycin-C in trabeculectomy and combined phacoemulsification and trabeculectomy: a randomized controlled trialMean intraocular pressure at each study visit in the collagen matrix (CM) and mitomycin-C (MMC) groups (p > 0.05 comparing CM with MMC at all the time points). The error bars represent standard deviations. Abbreviations: IOP = Intraocular Pressure; MMC = Mitomycin C; CM = Collagen MatrixBack to article page
