Trabeculectomy With Biodegradable Collagen Material: A Report of Two Cases

Purpose:To compare the surgical outcomes between trabeculectomy with a collagen matrix (Ologen ® ) insertion and conventional trabeculectomy. Methods: An ophthalmic examination, including tonometry and a slit lamp examination, was performed 1 week, 2 weeks, 1 month, 2 months, 4 months, 6 months, and 12 months postoperatively in glaucoma patients who underwent a trabeculectomy using Ologen ® (experimental group) or a conventional trabeculectomy (control group). Clinical features including success rate and complications were compared between the two groups. Results: In 21 eyes of the experimental group and 42 eyes of the control group, the success rates were 76% and 69%, respectively (p = 0.554). Needling with subconjunctival 5-fluorouracil injection or laser suture lysis of the scleral flap was required in three eyes (14.3%) in the experimental group and 18 eyes (42.9%) in the control group (p = 0.023). The types of complications differed, although the total number of complications did not differ between the two groups (23.8% vs. 19.0%, respectively; p = 0.745). The most common complication in the experimental group was an encapsulated bleb, which occurred in three eyes (14.3%), whereas an avascular bleb occurred in three eyes (7.1%) in the control group. Conclusions:The success rate of trabeculectomy with Ologen ® was comparable to that of conventional trabeculectomy.However, postoperative interventions were less commonly required after trabeculectomy with Ologen ® , and the complications differed between the groups. When choosing the surgical method and examining the postoperative condition, these differences should be considered.
