The investigators plan to evaluate the additive effect of intracameral and subconjunctival injections of bevacizumab in trabeculectomies with other antimetabolites.
Glaucoma filtration surgery is routinely utilized to control intraocular pressure in glaucomatous patients. It reduces IOP by creating a fistula between the anterior chamber and the subconjunctival space with a filtering bleb. Increased wound healing response affects the function and morphology of the filtering bleb, and wound healing involves a series of biological events beginning with hemostasis.
Corticosteroids and antifibrosis agents such as mitomycin C and 5-fluorouracil have been employed in trabeculectomy to delay wound healing and hence to improve the success rate of surgery by inhibiting inflammation and fibroblastic activity, and the use of these antiscarring agents is generally believed to improve the success rate of trabeculectomy.But this rate decreased with passing time and thus was not perfect.
Vascular endothelial growth factor is a pivotal stimulator of angiogenesis because its binding to VEGF receptors has been demonstrated to promote endothelial cell migration and proliferation in wound healing.Therefore, anti-VEGF agents may potentially modulate wound healing following glaucoma filtration surgery.
The principal objective of this study was to evaluate the additive effect of intracameral and subconjunctival injections of bevacizumab in trabeculectomy.
