Clinical Trial Summary

1. Study objective: To evaluate the relationship between filtering bleb vascularity and the surgical outcomes after trabeculectomy 2. Study design: A prospective study of 51 eyes of 44 patients after primary MMC-augmented trabeculectomy. The follow-up was 12 months.

Description:

Total vessel area of a filtering bleb was measured with ImageJ software on colour photographs of a filtering bleb on day 1, 14, 1, 3 and 6 months and 1 year after trabeculectomy. Blebs were classified clinically as successful (IOP below 18 mmHg and a >30% reduction in IOP without antiglaucoma medications or additional surgical interventions) or failed. Linear regression analysis was performed to determine the correlation of the bleb vascularity with IOP.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rates of surgical success	The successful bleb group consisted of eyes with IOP below 18 mmHg and a >30% reduction in IOP at 1 year after surgery without antiglaucoma medications or additional surgical interventions. Failed blebs were defined when IOP was over 18 mmHg, below 18 mmHg with antiglaucoma medications or if any additional surgical intervention was necessary	1 year
Secondary	Correlation of Bleb vascularity with IOP	Linear regression analysis was performed to determine the correlation of the bleb vascularity with IOP	6 months
