Effect of Mitomycin-C Augmented Trabeculectomy on Corneal Endothelial Cells

چکیده
PURPOSE To evaluate the effect of mitomycin-C (MMC) on corneal endothelial cell density (ECD) and morphology after trabeculectomy. METHODS In this prospective comparative case series, 31 eyes with glaucoma underwent trabeculectomy with (group I), or without (group II) MMC. Specular microscopy was performed pre-, and postoperatively at months 1 and 3. Outcome measures included central corneal endothelial cell count and coefficient of variation (CV) of cell size. RESULTS Overall, mean preoperative ECD was 2,135.8 ± 397.6 cells/mm(2); corresponding values at postoperative months 1 and 3 were 2,019.6 ± 447.2 cells/mm(2), and 1,991.4 ± 425.5 cells/mm(2), respectively (P > 0.05). Cell loss from month 1 to 3 was 1.3 % (P > 0.05). Subgroup analysis showed significant differences in endothelial cell loss at month 1 (P = 0.048) and month 3 (P = 0.014) between the MMC and control groups with no significant difference between the two groups in terms of cell loss from months 1 to 3, postoperatively (P = 0.968). Overall, mean pre-and postoperative CVs at months 1 and 3 were 27.38 ± 4.55, 27.96 ± 4.26, and 28.35 ± 4.47, respectively, with no significant difference between the two groups (P > 0.05). There was no correlation between preoperative central endothelial cell density (CECD) and MMC related cell loss. CONCLUSION MMC application in trabeculectomy seems to cause a small but significant corneal endothelial loss. Most of the damage occurs intraoperatively, or in the early postoperative period, however progressive endothelial cell loss is not a major concern.

PURPOSE To investigate the safety and synergistic effect of topical bevacizumab after trabeculectomy surgery with mitomycin C (MMC). METHODS In this prospective, non-randomized, comparative interventional study, 40 eyes from 40 patients with uncontrolled open-angle glaucoma were studied after they underwent primary trabeculectomy with mitomycin C (0.02% for 2 min). Following the procedure top...

PURPOSE To compare trabeculectomy with mitomycin-C (MMC) application before versus after scleral flap dissection in terms of corneal endothelial cell loss and surgical outcomes. METHODS In this double blind clinical trial, patients were randomized to MMC 0.02% application before (group A) or after (group B) scleral flap dissection. The main outcome measure was corneal endothelial cell density...
