Sutureless versus conventional deep sclerectomy for management of open angle glaucoma

Area of Science:

• Ophthalmology
• Surgical Innovation
• Glaucoma Research

Background:

• Open-angle glaucoma (OAG) management often requires surgical intervention to lower intraocular pressure (IOP).
• Deep sclerectomy is a surgical technique used to treat OAG.
• Sutureless deep sclerectomy represents a potential modification to enhance surgical outcomes.

Purpose of the Study:

• To compare the efficacy of sutureless deep sclerectomy versus conventional deep sclerectomy in reducing IOP.
• To evaluate the impact of both surgical techniques on the need for anti-glaucoma medications.
• To assess the complication rates and bleb functionality following each surgical procedure.

Main Methods:

• A prospective, interventional, randomized comparative study involving 60 eyes of 50 patients with OAG.
• Patients were divided into two groups: one undergoing sutureless deep sclerectomy (Group A) and the other conventional deep sclerectomy (Group B).
• Intraocular pressure (IOP) reduction, medication use, complications, and bleb functionality (using ultrasound biomicroscopy - UBM) were monitored over six months.

Main Results:

• Both surgical groups demonstrated significant IOP reduction throughout the six-month study period.
• No statistically significant difference was observed in the percentage of IOP reduction between sutureless and conventional deep sclerectomy.
• Postoperative anti-glaucoma medication use decreased significantly in both groups, with no significant difference between them. Complication rates were low and comparable.

Conclusions:

• Sutureless deep sclerectomy is a safe and effective modification for managing open-angle glaucoma.
• The technique provides significant IOP reduction comparable to conventional deep sclerectomy.
• Further research may explore long-term outcomes and patient-reported benefits.
