Filtering bleb revision. Techniques and outcome

BACKGROUND: The surgical management and outcome of bleb-related complications such as leaking blebs,overfiltration and blebitis are reported. METHODS: A retrospective analysis was carried out of 35 patients who underwent surgical repair of the filtering bleb in our hospital between 1991 and 2000. RESULTS: Surgical techniques used were autologous blood injection, fibrin glue injection, conjunctival suturing, resuturing of the trabeculectomy flap, bleb excision, conjunctival advancement, lyodura and tenon patching. In the eyes with leaking blebs the mean preoperative intraocular pressure (IOP) was 11.6+/-10.3 mmHg.After an average followup of 12 months the IOP was 11.9+/-3.3 mmHg. In the eyes with overfiltration the mean IOP was 2.4+/-1.5 mmHg and after an average follow-up of 18 months the mean IOP increased to 13.5+/-3.7 mmHg. In 77.1% the IOP was regulated between 8 and 21 mmHg without glaucoma medication. Mean visual acuity improved by 3.6+/-5.9 lines postoperatively. CONCLUSION: Surgical bleb revision has a high success rate with regard to maintaining a functioning filtering bleb and to preserving vision.

Surgical repair of leaking filtering blebs

PURPOSE: To report the surgical management of leaking filtering blebs occurring after blebitis or persistent hypotony. DESIGN: Retrospective, noncomparative case series. PARTICIPANTS: Twenty-two eyes of 20 patients with late bleb leak, blebitis or endophthalmitis, hypotony maculopathy, or bleb dysesthesia on presentation to the glaucoma service who required surgical bleb revision from 1990 through 1999. INTERVENTION: Pedicle flap, partial excision, and advancement or free conjunctival autologous graft techniques for surgical bleb revision. Type of bleb revision was dependent on the dimensions of the bleb and quality of surrounding conjunctiva. MAIN OUTCOME MEASURES: Preoperative and postoperative intraocular pressure (IOP), status of bleb leak, reoperation for glaucoma, or requirement for postrevision glaucoma medical therapy, with success defined as the need for two or fewer glaucoma medications after revision. RESULTS: Eighty-six percent (19/22) of eyes that underwent surgical bleb revision had resolution of leak and IOP control using two or fewer medications after one or more bleb revisions. The preoperative IOP (mean +/- standard deviation) was 3.7 +/- 2.6 mmHg (range, 0-8 mmHg). After an average follow-up of 21 months (range, 8-108 months), the IOP was 11.0 +/- 4.4 mmHg for patients taking 0.6 +/- 1.0 glaucoma medications. Eighteen percent (4/22) of eyes required two or more bleb revisions. In one eye, an IOP spike of 36 mmHg developed after revision, which required laser suture lysis on two occasions before the IOP was significantly lowered. The three failures were: one eye that required three or more medications for IOP control, a patient whose eye had a persistent leak after revision and who was not mentally competent to undergo repeat revision, and one eye that required combined glaucoma and cataract surgery after revision. CONCLUSIONS: Surgical bleb revision has a high success rate of closing late bleb leaks, maintaining glaucoma control, and preserving vision, with few postoperative complications. The appropriate surgical procedure for revision must be based on the individual clinical situation and can result in successful bleb revision.

Slit-lamp needle revision of failed filtering blebs using high-dose mitomycin C

PURPOSE: To investigate the efficacy of bleb needle revision with high-dose mitomycin C in reviving failed filtering blebs after 1 year. PATIENTS AND METHODS: We reviewed the charts of 44 patients with one eye that had undergone bleb needle revision with a mixture of 0.1 mL of mitomycin (0.4 mg/mL) mixed with 0.1 mL of non-preserved 1% lidocaine. At least 12 months of follow-up were required. A successful bleb needle revision was defined as one that did not require a subsequent needling, glaucoma surgery, or medication to reach an intraocular pressure (IOP) greater than 4 mm Hg but less than 22 mm Hg. A qualified success was defined as a successful bleb needle revision that required subsequent needling or medication. RESULTS: The bleb needle revision with high-dose mitomycin was a success or qualified success after 12 months in 28 patients or 64% (95% confidence interval, 50% to 78%). The baseline IOP in these patients was 26.7 +/- 8.2 mm Hg (range 15 to 48 mm Hg) using an average of 1.5 +/- 1.5 glaucoma medications. The IOP after 1 year was 13.6 +/- 4.0 (range 6 to 21 mm Hg) with an average of 0.5 +/- 0.8 medications. Of 44 patients, 17 (39%) were successes and 11 (25%) were qualified successes. CONCLUSION: Bleb needle revision with high-dose MMC was effective in reducing the IOP in 64% of eyes with a failed filtering bleb with minimal long-term complications.

Midterm follow-up of necrotic bleb excision and advancement of the fornical conjunctiva

Mitomycin C has improved the success rate of glaucoma filtering surgery in patients at high risk for surgical failure. However chronic hypotony is marked by decreased vision and a late-onset leaking bleb after filtration surgery using mitomycin C. Bleb excision and conjunctival advancement is the method of choice to repair bleb leakage and chronic hypotony. Five eyes from five patients were received glaucoma filtration surgery with topical mitomycin C. All of the patients' blebs were avascular and transparent. The reasons for bleb excision were two spontaneous bleb leaks, two traumatic bleb leaks and one case of severe irritation. The mean follow-up period was 18.4 +/- 8.3 months (ten to 29 months). Cataract surgery was combined in one eye. Postoperative intraocular pressure (IOP) increased from 2.3 +/- 1.5 mmHg to 9.5 +/- 3.7 mmHg at nine months postoperatively in four eyes. It went from 28 mmHg to 40 mmHg in one patient with uveitis, for whom a second trabeculectomy with mitomycin C; 0.4 mg/ml for 3 minutes, was performed. After surgery, IOP decreased to 4 mmHg in three months. Postoperative visual acuity improved four snellen lines in three eyes. A partially avascular bleb recurred in three eyes, a corneal bleb in one eye and blepharoptosis, which disappeared spontaneously at four months postoperatively, in one eye. Necrotic bleb excision and advancement of fornical conjunctiva were useful methods to increase IOP and to improve visual acuity for the patient experiencing irritation symptoms, and for leaking blebs, and hypotonic maculopathy.     

针刺分离联合5-氟尿嘧啶注射治疗功能不良滤过泡的临床观察

目的：观察针刺分离联合5-氟尿嘧啶(5-FU)结膜下注射治疗青光眼小梁切除术后不同时期功能不良滤过泡的临床疗效、影响因素及安全性。
　　方法：对76例83眼小梁切除术后功能不良滤过泡进行针刺分离联合5-FU 结膜下注射,针刺分离后随访12mo,对随访时患者的眼压( intraocular pressure,IOP)、用药次数、角膜内皮、滤过泡的形态及并发症进行观察记录。
　　结果：针刺分离前患者的眼压为35.3依5.8mmHg(1kPa =7.5mmHg),随访结束时眼压为17.0依4.3mmHg,两者差异有显著统计学意义(t =24.846,P<0.01);术前平均用药种类为1.7依0.9种,随访结束时平均用药种类为0.4依0.7种,两者差异有显著统计学意义(t =11.145,P<0.01)。针刺分离12mo 后滤过泡成功率为89.2%,其中完全成功率为69.9%,Kaplan-Meier 生存分析示83眼平均生存时间为11.0mo(95% CI：10.3~11.6)。青光眼的类型、滤过手术是否使用丝裂霉素 C(mitomycin C,MMC)、患者年龄及滤过手术至针刺分离的间隔时间对针刺分离效果无影响,针刺分离前滤过泡形态对针刺分离效果有影响,包囊型滤过泡较扁平型滤过泡针刺分离效果好,滤过手术后3mo 内进行针刺分离的患者比>3mo 的患者平均针刺分离的次数明显减少。
　　结论：针刺分离联合5-FU 结膜下注射是治疗小梁切除术后功能不良滤过泡的一种安全、有效的简单处理方法,小梁切除术后发现功能不良滤过泡应早期处理。     

Needle revision of failed filtering blebs using 5-Fluorouracil and a combined ab-externo and ab-interno approach

PURPOSE: To evaluate a surgical technique to revise a failed filtering bleb using subconjunctival 5-Fluorouracil with a combined ab-externo and ab-interno approach. PATIENTS AND METHODS: This study is a retrospective review of the outcome of 77 consecutive bleb revisions, with greater than 6-month follow-up, performed by a single glaucoma surgeon (MW). All eyes had previously functioning filtering blebs with currently inadequately controlled intraocular pressures (IOP) prior to the bleb revisions. All surgery was performed in the operating room, using a retrobulbar injection and a microscope. Visco-elastic was injected into the anterior chamber. 5-Fluorouracil (0.1 mL; 50 mg/ml) was infiltrated around the bleb. A 30-gauge needle was used to lyse subconjunctival fibrosis and episcleral scar tissue binding down the scleral flap, and elevate the scleral flap. Through an inferior paracentesis, a cyclodialysis spatula was used to confirm and enlarge the communication with the subconjunctival space. The main outcome measurements were IOP and number of glaucoma medications. A successful outcome was defined as a 20% reduction from baseline IOP and a maximum IOP of 18 mm Hg, with or without medications, and a minimal follow-up of 6 months. RESULTS: 52% of patients achieved success after one revision with an average follow-up of 29.6 +/- 14.4 months. In successful cases, the mean IOP decreased from 22.7 +/- 4.5 mm Hg to 11.3 +/- 3.5 mm Hg and medications were reduced from an average of 2.2 +/- 1.1 to 0.4 +/- 0.7. Kaplan-Meier survival analysis calculated a success of 77% at 1 year, 68% at 2 years, and 58% at 3 years. CONCLUSIONS: In failed filtering blebs, needle revision with 5-Fluorouracil and a combined ab-externo and ab-interno approach results in high success and low complication rates. The outcome of this procedure compares favorably with previously reported revision techniques.

Bleb reduction and bleb repair after trabeculectomy

OBJECTIVE: To describe methods and outcomes for repair of bleb-related complications of trabeculectomy surgery. DESIGN: Retrospective, consecutive, noncomparative case series. PARTICIPANTS: Thirty-one persons having bleb revision by two surgeons at the Wilmer Institute from 1994 to the present. INTERVENTION: One of two types of revision surgery was performed: bleb reduction to decrease symptoms from large blebs or bleb repair to improve hypotony, using conjunctival rotation flap or free conjunctival autograft. MAIN OUTCOME MEASURES: Visual acuity, intraocular pressure (IOP), reported symptoms, complications, and number of glaucoma medications at the final visit. RESULTS: The mean time from trabeculectomy to bleb revision was 4.4 years. Bleb reduction was performed because of symptomatic, high blebs in 11 eyes of 11 persons. Bleb repair was performed to end bleb leakage in 13 eyes of 13 persons and to increase IOP in 8 eyes of 7 persons with hypotony. Median visual acuity improved from 20/50 before revision to 20/30 at most recent follow-up. Mean IOP increased after treatment from 7.7+/-4.9 to 12.4+/-4.0 mmHg (P < 0.001). Symptoms that caused the revision surgery were eliminated in all cases. None of these eyes has lost IOP control, none has required repeat trabeculectomy, and only 2 of the 32 (6%) require topical glaucoma medication. More than one revision procedure was required in 8 of 32 (25%) eyes. CONCLUSIONS: Surgical bleb revisions for complications after trabeculectomy surgery are safe and effective. Bleb reduction for large, symptomatic blebs or bleb repair for leaking blebs and hypotony did not lead to loss of IOP control.
