The Effect of Topical and Subconjunctival Coenzyme Q10 on Wound Healing Modulation in an Experimental Trabeculectomy Model

Abstract

Purpose: To investigate the wound healing effect of topical and subconjunctival Coenzyme Q10 (CoQ) in an experimental trabeculectomy model, and to compare the outcomes with mitomycin C and bevacizumab. Materials and Methods: Thirty eyes of 27 Wistar Albino rats were included. Group 1 was the control group and the other four groups were mitomycin C (group 2), topical CoQ (group 3), subconjunctival CoQ (group 4), and bevacizumab (group 5). Conjunctival and scleral incisions were made to mimic the trabeculectomy wound. After the rats were sacrifi ced, histological sections were examined for vasculogenesis, VEGF and TGF-β1 positivity. Results: The mean vascularization score was lowest in groups 3 and 4 (0.5±0.55). It was followed by group 2 (1.0± 0.89), group 5 (1.5±1.0), and control group (2.5±0.55). The eyes in group 2, 3 and 4 showed signifi cantly less vascularization than the control group (p = 0.015, p
