Abstract
Purpose. Comparative evaluation of the clinical and functional results of post-operative adjuvant subconjunctival administration of 5-fluororacil after a non-penetrating deep sclerectomy (npdS) compared to the control group. Material and methods. A retrospective study was conducted of two groups of patients with primary open-angle glaucoma who had undergone npdS and received at least 1 subconjunctival injection of 5-fluorouracil in the postoperative period. Group 1 is patients who have received post-surgical 5-fluoride injection using a standard procedure. group 2 — patients who received the injection according to the proposed method. The comparison included: best correction visual acuity (BcVa), intraocular pressure (Iop), frequency of corneal complications. Results. Demographic characteristics and preoperative BcVa and Iop parameters did not differ between the compared groups. Corneal epithelial defects stained with fluorescein were statistically significantly more common in group 1 compared to group 2, p < 0.001. The highest decrease of Iop (p = 0.042) and lower loss of BcVa (p < 0.001) 4 weeks after npdS was observed in group 2. Conclusions. The use of the modified method provides greater safety and efficacy of 5-fluorouracil administration in the postoperative period of npdS compared to the control group. Keywords: 5-fluorouracil, glaucoma, corneal erosion, toxicity, prevention of complications, injection
