Abstrakt: Purpose: The aim of the study is to evaluate the surgical outcome of stab incision glaucoma surgery (SIGS) and compare it with radiofrequency-assisted stab incision in the treatment of uncontrolled open-angle glaucoma.
Patients and Methods: A prospective, interventional study included 50 eyes who were assigned into two equal groups: Group A underwent stab incision procedure with preoperative subconjunctival (SC) mitomycin-C (MMC) and Group B underwent radiofrequency-assisted technique without MMC. Intraoperative and postoperative complications, visual acuity, intraocular pressure (IOP), and bleb status were evaluated up to 12 months.
Results: Mean preoperative IOP in Group A was 26.96 ± 2.42 reduced to 13.43 ± 2.31 while in Group B was 27.20 ± 3.57 reduced to 15.48 ± 3.68 mmHg ( P < 0.001) with a mean reduction of 50.61% ± 8.42% and 43.56% ± 12.83%, 12 months postoperatively in Groups A and B, respectively. Non-basal peripheral iridectomy was the most encountered intraoperative complication in 8 eyes (32%) and 9 eyes (36%) and hypotony was the most reported postoperative complication in 5 eyes (20%) and 9 eyes (36%) in Groups A and B, respectively. Flat bleb area had been reported at the end of follow-up time in 3 eyes (13%) and 7 eyes (30%) in Groups A and B, respectively. Complete success rate was 52.2% and 28.6% while qualified success rate was 28.8% and 42.9% in Groups A and B, respectively.
Conclusion: SIGS with SC MMC is an effective and safe procedure in IOP lowering, while radiofrequency-assisted stab incision had high incidence of subconjunctival scarring and ostium closure.
Competing Interests: There are no conflicts of interest.
