Efficacy and Safety of Sutureless Deep Sclerectomy in Juvenile and Adult Open Angle Glaucoma: 2-Year Outcomes

Sutureless deep sclerectomy (SDS) achieved significant reduction in primary open angle glaucoma (POAG) and juvenile open angle glaucoma (JOAG).

To assess long-term results of SDS in cases with POAG and JOAG.

A prospective interventional study included 84 eyes of 54 patients underwent SDS with the superficial scleral flap left un-sutured. Changes in intraocular pressure (IOP) were recorded over 2 years. Success was defined according to the world glaucoma association criteria: Criterion A: IOP ≤18 mmHg and IOP reduction ≥30% from the preoperative status without medications [complete success (A1)], with and without medications [qualified success (A2)]. Criterion B: IOP ≤15 mmHg and IOP reduction ≥40% from the preoperative status without medications [complete success (B1)], with and without medications [qualified success (B2)].

There was statistically significant reduction in IOP compared with the preoperative IOP (mean IOP = 26.21± 10.46 mmHg) starting from 1 st postoperative day (mean IOP = 7.18 ± 1.8 mmHg) till the end of follow-up period at 2 years (mean IOP = 15.85± 4.46) ( P < 0.001). Also, number of medications dropped significantly from 3.27 ± 1.14 to 0.82 ± 0.97 at the end of follow up period. At 2 years complete success (A1) was achieved in 57.1% and qualified success (A2) was achieved in 91.6% of cases. Subgroup analysis into males and females, POAG and JOAG showed no statistically significant difference between subgroups regarding IOP reduction.

SDS is an effective and safe modification to deep sclerectomy in cases with POAG and JOAG.
