Abstract

A likely filtering bleb from a deep sclerectomy may fail due to post-operative scar formation. Currently, needle revision is a minimally invasive intervention used to salvage the function of a failed deep sclerectomy bleb. This study included 28 failed deep sclerectomy eyes from 23 patients at the Vietnam National Eye Hospital. The mean intraocular pressure (IOP) decreased significantly from a baseline mean of 26.14 ± 5.41mmHg to 14.46 ± 3.47mmHg at 1 month, 14.46 ± 4.81mmHg at 2 months, 14.00 ± 4.81mmHg at 3 months, and 14.78 ± 3.33mmHg at 6 months. The complete success rates were 85.71% and 78.57% at 3 months and 6 months after needle revision, respectively. Complications included subconjunctival hemorrhage in 14 eyes (50%), iris incarceration in 2 eyes (7.2%), and keratitis in 2 eyes (7.2%). In conclusion, needle revision is a simple and effective technique with the potential for widespread application in eye centers.
