Abstract

PURPOSE: To evaluate safety and efficacy of SP shunt Vs Trabeculectomy in POAG.

STUDY DESIGN: Hospital-based randomized prospective study.

MATERIALS AND METHODS: This was a hospital-based randomised study. Fifty eyes of 50 POAG patients were divided into 3 groups based on preoperative IOP range. SIGS was done with polymethylmethacrylate (PMMA) implants made from haptics of intraocular lenses. All patients were followed up after 1 day, 1 week, 1 month, 3 months, 6 months, and 12 months. Preoperative IOP range was from 25.62 ± 1.72 to 41.66 ± 1.15 mmHg. Postoperative success was defined as IOP <21 mmHg at 1 month in the absence of additional anti-glaucoma medication or other treatment.
RESULT: A significant reduction in IOP was observed post-surgery in all three groups. No intraoperative complications were observed.
CONCLUSION: SIGS with SP shunt is a safe and cost-effective (<1 US dollar) procedure for control of IOP in POAG patients especially those with moderately elevated IOPs.
