Needle revision of failing and failed trabeculectomy blebs with adjunctive 5-fluorouracil: survival analysis

PURPOSE: To report the outcome of 5-fluorouracil (5-FU)-augmented bleb needling revision of failed and failing filtration blebs and to identify risk factors for failure, indicators for success, and any complications of the procedure. DESIGN: Prospective, observational, noncomparative, interventional case series with survival analysis. METHODS: The results of 101 bleb needling procedures augmented with subconjunctival 5-FU injection were determined after a minimum follow-up of 9 months. Kaplan-Meier plots were constructed and a Cox proportional hazards regression analysis was performed to assess the association between study factors and time to failure. MAIN OUTCOME MEASURES: Reduction in intraocular pressure (IOP) by 2 criteria (<22 mmHg, >30%), glaucoma medications, complications, and factors associated with outcome. RESULTS: At the time of their last follow-up visit, 60 eyes had an IOP <22 mmHg, mean IOP being reduced from 26.5 mmHg to 15 mmHg [corrected] after a median of 1 needling procedure (mean, 1.6). The median interval between the "index" filtration surgery and the first (or only) needling procedure was 3.1 months, with a range of 10 days to 11 years. There was a reduction in mean number of topical antiglaucoma agents from 0.7 to 0.2 per successful eye and a median follow-up duration of 18.7 months (range, 9.3-52.8 months [corrected]). Thus, the overall cross-sectional success rate of the procedure at the time of the last visit was 59.4%. Strong evidence was found for an association between the immediate attainment of a low IOP (<11 mmHg) and longer survival times. None of the other proposed factors that may have affected outcome were identified as having a statistically significant effect; however, this may have been the result of the low statistical power for some of the factors in this study. CONCLUSIONS: These data suggest that bleb needling augmented with 5-FU is a safe and effective method by which a significant number of failed or failing filtration blebs can be rescued from failure. Attaining an immediate reduction in IOP to <11 mmHg seems to be a favorable factor with respect to reasonably long-term efficacy .     

Operative revision of non-functioning filtering blebs with 5-fluorouracil to regain intraocular pressure control

PURPOSE: To determine the efficacy of extensive microsurgical needling revision of failed filtering blebs followed by serial 5-fluorouracil subconjunctival injections. METHODS: Thirty-six eyes of 34 consecutive patients with progressive open-angle glaucoma refractory to topical therapy submitted to needling revision as a major procedure. All patients required multiple antiglaucoma medications preoperatively, and had completely flat or densely encapsulated filtering blebs. All patients underwent elaborate needling revision (limbus to superior rectus >8 mm diameter, >3 mm elevation, entry-site sutured with 8-0 vicryl and bleb reformed via paracentesis with viscoelastic) in the operating room, followed by serial 5-fluorouracil. The patients were followed for up to 6 months postoperatively. The main outcome measures were intraocular pressure (IOP) and the number of antiglaucoma medications used. RESULTS: Thirty-one eyes (86%) maintained mean IOP below 15 mmHg postneedling without medication. Overall the mean IOP postneedling was >9 mmHg lower than medicated preoperative levels (P < 0.0001). IOP reduction in encapsulated blebs was marginally superior to that in flat blebs. CONCLUSIONS: Extensive needling revision in the operating room is safe, straightforward, and produces reproducible restoration of filtering function.     

Clinical study on interferon treatment of early scarring in filtering bleb

 Purpose: To investigate the effectiveness of needle revision combined with subconjuctival injection of interferon α-2b in reversing early scarring of filtering blebs following trabeculectomy surgery. Methods: Twenty-five  glaucoma patients (31 eyes) who presented with scarred or encapsulated filtering bleb after glaucoma surgery underwent needle revision in combination with subconjuctival injection of interferon α-2b, and were followed for 12 months. Intraocular pressure (IOP) and filtering bleb morphology were observed post treatment. Results: The mean time until scarring occurred was 21.0±7.4 days. The average time between recognition of bleb scarring and completion of needle revision was 2.2±0.8 days. The time interval between surgery and needle revision was inversely correlated with the time until needle revision (r = -0.694, P < 0.001). The mean IOPs before and after needle revision were 24.2±2.7mmHg and 19.6±3.8mmHg, respectively (t = 5.916,P < 0.001). At the 12-month follow-up visit, 18 eyes (58.1%) achieved complete success in IOP control, and 6 eyes (19.4%) had conditional success. The overall success rate for needling was thus 77.4%. Subconjunctival hemorrhage was observed in 4 eyes during the needle revision procedure. Punctate staining was found in the corneal epithelium of 2 eyes. Shallow  nterior chamber (Grade I or II) was identified in 5 eyes.  Conclusion: Slit-lamp needle revision combined with subconjunctival injection of interferon α-2b may be efficacious in the treatment of early scarring of filtering blebs, is easy and safe to perform, and may be considered for more widespread application.     

Late Needling mit 5-Fluorouracil bei drohender Sickerkissenvernarbung

Background

Evaluation of needling and 5-fluorouracil (5-FU) injections more than 4 months after preceding filtration surgery.

Patients and Method

Retrospective analysis of 17 eyes in 14 patients who underwent needling of the filtering bleb and administration of 5-FU by injection at least 4 months after trabeculectomy (TE) with mitomycin C (MMC; same surgeon throughout). Complete success was defined as a reduction of intraocular pressure (IOP) by >30% from the baseline value without further medication and, in cases of primary open-angle glaucoma, IOP of 18 mmHg. The mean period of follow-up was 8.1 months (3–24 months).

Results

One to four needlings (Ø 1.6) with one to five injections (Ø 3.1) of 5-FU were performed as required according to clinical need an average of 31.3 months (4–108 m) after TE. The mean baseline IOP was 25 mmHg (±SD 6.02; median 25 mmHg). After needling and 5-FU injection the mean IOD at the last hospital visit was 13.64 mmHg (±SD 5.2, median 13 mmHg; p<0,001). Complete success was achieved in 82.4% of these cases. The mean reduction in IOP was 11.2 mmHg (0–22 mmHg). In the cases with successful outcome (14 of 17 eyes) the mean IOP reduction from baseline was 55%. Three eyes required further treatment. Complications encountered were hyphaema (2 cases), subconjunctival bleeding (1 case) and corneal erosion (3 cases).

Conclusion

Late needling and injections of 5-FU can restore filtering bleb function even over 4 months after initial surgery. The high success rate and low incidence of complications together with the simple procedure justify regarding this approach as an alternative that can be used before passing on to more invasive interventions.
