Purpose:
The main purpose of the study was to demonstrate the procedure and evaluate efficacy of intrascleral placement of peripheral iris as a method of treatment in advanced glaucoma cases.
Material And Methods:
24 patients with advanced glaucoma were enrolled in the study. Surgery was performed. The IOP was measured before the surgery, 5 days, 1 month and 6 months after the surgery. The effectiveness of treatment and rate of complications were assessed.
Results:
Average IOP after surgery significantly decreased from 46.16 +/- 8.99 mmHg to 14.33 +/- 4.59 at the 5th day after the surgery, 17.20 +/- 3.88 at 1 month and 17.75 +/- 4.09 at 6 months. The efficacy of treatment was 91.66% at 5th day, 87.5% at 1 month and 83.33% at 6 months.
Conclusions:
The findings of the study suggest that this technique is effective in advanced glaucoma cases and is associated with low complication rate.
