ABSTRACT: Background
To compare 6?month outcomes of bleb needling performed in the clinic vs. the operating room (OR) in adult glaucoma patients with failed bleb.Methods
A retrospective case series of 47 eyes from 41 glaucoma patients who received needling with mitomycin C (MMC) of scarred bleb from prior bleb-forming procedures in clinic (32 eyes) vs. the OR (15 eyes), including trabeculectomy (14 eyes), ExPress shunt (16 eyes), and ab-interno XEN gel stent (17 eyes). The primary outcome was needling success, defined as IOP???18?mmHg on 0 glaucoma medications without requiring an additional IOP lowering procedure within 6?months after needling.Results
At 6?months, bleb needling success rate was similar when performed in the clinic vs. in the OR (28% vs. 20%, P?=?0.54). Success rate was not statistically different in patients with prior trabeculectomy, ExPress shunt, and XEN gel stent (29% vs. 38% vs. 12%, P?=?0.26). When comparing clinic vs. the OR needling procedures at 6?months, there was no difference in mean IOP (14.2 vs. 14.9?mmHg, P?=?0.73), mean glaucoma medications (1.4 vs. 1.7, P?=?0.69), additional IOP-lowering procedure rate (16% vs. 27%, P?=?0.37), or complication rate (0% vs. 7%, P?=?0.32).Conclusion
Bleb needling with MMC in clinic may be a safe and effective way to revise failed bleb after trabeculectomy, ExPress shunt, and XEN gel stent procedures when compared to needling in the OR.
