Comparison between percentage of reduction in both groups showed no statistically significant difference. Also, use of anti-glaucoma medications dropped significantly at 6 months postoperatively in both groups with no significant difference between the 2 groups. Regarding reported complications, 12.9% in group A and 10.3% in group B presented with non-serious complications. One month postoperatively, UBM detected non-functioning blebs in 6.4% of group A and 3.4% in group B.
