Biodegradable 3D-Porous Collagen Matrix (Ologen) Compared with Mitomycin C for Treatment of Primary Open-Angle Glaucoma: Results at 5 Years

Figure 2

(a) The mean bleb extent during the postoperative course. The bleb extent was increased from 1 day after surgery to 5-year follow-up visit. The extent in Ologen group was larger than MMC group. (b) The mean bleb height during the postoperative course. In the early postoperative stage (up to 14 days), bleb height in Ologen group was higher than MMC group. From 14 days to 5-year visit, the bleb height was similar in both groups. (c) The mean bleb vascularity during the follow-up visit. In the early postoperative stage (up to 14 days), bleb vascularity in both groups was similar, the vascularity of MMC group was reduced from 1 month. At 5-year follow-up visit, the bleb vascularity in Ologen group was more than MMC group.
