Outcomes: Trabeculectomy Bleb Needle Revision With XXXX .

@entity1 @entity260 @entity726 @entity1487
PURPOSE: To evaluate outcomes of trabeculectomy bleb needle revision with @entity1487 augmentation performed in the operating theater. METHODS: Retrospective study of all @entity1 undergoing trabeculectomy bleb needle revisions in the operating theater performed by a single surgeon in a metropolitan hospital in Australia. A total of 51 needle revisions were performed on 33 eyes over a mean follow-up time of 1.81  1.56 years. RESULTS: A total of 29% achieved intraocular pressure (IOP)  <=20 mm Hg off all @entity726 medications, and an additional 39% achieved qualified success with the addition of @entity726 medications, giving overall success of 68%. Analyzing success rate for target IOP <=16 mm Hg, 24% achieved target off all @entity726 medications, 35% achieved qualified success with the addition of @entity726 medications, giving an overall success rate of 59%. There was a statistically significant improvement in IOP, as compared with preoperative levels, at all timepoints postoperatively (P<0.05). However, number of @entity726 medications remained unchanged (P>0.05) contributing to the high percentage of qualified successes. Visual acuity remained unchanged and there were no major @entity260 . The Kaplan-Meier survival shows a survival rate of 60% with IOP <=20 mm Hg and 40% for IOP <=16 mm Hg at 5 years. CONCLUSIONS: Trabeculectomy needle revision is a useful option for the management of elevated IOP in the presence of a failed or failing trabeculectomy bleb. However, as with trabeculectomy, there tends to be a failure rate over time. This often leads to reinstitution of @entity726 medications and/or further needle revisions to maintain IOPs at target level. The procedure itself is minimally invasive with an acceptable safety profile.
