The experience of using biodegradable drainage in combination with traditional sinustrabeculectomy

Purpose: analysis and comparison of the degree of intraocular pressure (IOP) compensation, the presence and nature of postoperative complications in traditional sinustrabeculectomy (STE) and STE using biodegradable drainage. Material and Methods. Surgical intervention - sinustrabeculectomy (53 - traditional, 53 - using drainage, DDA drainage type) was performed with stationary diagnosis (106 patients) with a verified diagnosis of "primary open-angle glaucoma" (106 eyes). A comparative analysis was carried out for the stages of glaucoma, the degree of compensation of IOP, the presence and nature of postoperative complications. Results. In the course of sinustrabeculectomy with the use of drainage, a high level of the degree of IOP compensation and a low level of postoperative complications were noted in comparison with traditional sinustrabeculectomy. Gradual resorption of drainage prevents sharp decrease in ophthalmotonus, which allows to significantly reduce the risk of postoperative complications. At the same time, the presence of drainage interferes with the adhesion of the scleral flap and contributes to the gradual formation of a filtration pillow, which, accordingly, leads to a prolonged hypotensive effect. Conclusion. Sinustrabeculectomy with the use of drainage is pathogenetically grounded, which does not complicate the operation, it allows to achieve a persistent and prolonged hypotensive effect and to reduce the risk of postoperative complications.
