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.     

Restoring the function of the failed bleb

Failure of the filtering bleb after trabeculectomy with a gonioscopically patent drainage cleft is likely to be due to: encapsulation of the bleb; flattening of the bleb; or cystoid bleb. Encapsulated blebs and flattened blebs are usually associated with a high intraocular pressure (IOP) while cystoid blebs are not, but corneal ulceration due to the prominent cystoid bleb may make revision of the bleb necessary. If the IOP is raised it is best to proceed quickly to needling of the bleb using 5-fluorouracil. Sixteen patients underwent needling of the bleb, eight with encapsulated, six flattened and two cystoid blebs. Chronic open-angle glaucoma (10 cases) was the commonest glaucoma. Twelve patients obtained satisfactory control of IOP with mean pre-needling IOP for encapsulated blebs of 32 mmHg (4.27 kPa), flattened blebs 36 mmHg (4.8 kPa) and cystoid blebs 16 mmHg (2.13 kPa), while post-needling IOP for encapsulated blebs was 12 mmHg (1.6 kPa), flattened blebs 13 mmHg (1.73 kPa) and cystoid blebs 12 mmHg (1.6 kPa). Mean follow-up for encapsulated blebs was 15, flattened blebs 11 and for cystoid blebs nine months. Mean time between trabeculectomy and needling was: for encapsulated blebs 16 days; flattened blebs 24 days; and cystoid blebs 19 months.     

小梁切除术联合生物羊膜移植治疗难治性青光眼的疗效

目的：评价小梁切除术联合生物羊膜治疗难治性青光眼的临床疗效。

方法：包括29例29眼具有高危因素如新生血管、葡萄膜炎、无晶状体、人工晶状体和发育性的难治性青光眼。13例行小梁切除术联合羊膜移植,16例行小梁切除术。术后观察、比较的指标包括：术后眼压、抗青光眼药物使用数量、滤过泡形态特点以及术后并发症。所有研究对象随访12mo。

结果：术后6mo,手术完全成功：羊膜组11/13(84.6%),对照组10/16(62.5%)(P<0.05); 术后12mo,手术完全成功：羊膜组10/13(76.9%),对照组10/16(62.5%)(P<0.05)。术后12mo,羊膜组和对照组眼压分别从术前50.3±11.3,49.7±10.7mmHg降至15.7±1.1,19.8±2.3mmHg(P<0.05)。由于滤过过强,对照组术后早期出现低眼压3例(18.8%),羊膜组无1例发生; 对照组出现包裹性滤过泡6例(37.5%),羊膜组仅出现1例(7.7%)。

结论：小梁切除术联合羊膜移植治疗难治性青光眼与单纯小梁切除术相比,具有手术成功率高,术后眼压控制良好、平稳,术后并发症发生率低的特点。

结论：下方小梁切除术操作难度相对较大,但对于青光眼滤过术后眼压控制不佳的患者,仍可以作为一种安全有效的治疗方案。     

The role of needle revision and 5-fluorouracil application over the filtration site in the management of bleb failure after trabeculectomy: a prospective study

Fifty-three eyes of 49 consecutive patients with an intraocular pressure (IOP) over 21 mmHg; without bleb or with a thick, flat bleb after the second postoperative week following trabeculectomy were included in the study. Needle revision was performed with a 26-gauge tuberculin syringe containing 5 mg (0.2 ml) 5-FU in a period of 2 weeks to 10 months postoperatively after unsuccessful digital massage and/or laser suture-lysis. 5-FU injection was not performed when a bleb formation was observed during needling. In case of no bleb formation, 5-FU was injected subconjunctivally over the scleral flap area and repeated a maximum of six times until a functioning bleb was maintained. Needle revision was successful in 14 of 53 eyes (26.4%) as an initial procedure and nine (16.9%) eyes maintained success. Forty-four eyes (83.1%) had 5-FU injection since needle revision did not provide bleb formation (39 eyes) or did not maintain initial success (five eyes). Mean IOP was 27.8±4.7 mmHg (range, 22–41) before any intervention and decreased to 20.5±4.8 mmHg (range, 8–35) after a mean follow-up of 25.1 months and the difference was statistically significant (p<0.001). Mean IOP after needle revision in 14 patients was 18.9±4.9 mmHg (range, 8–29) and 16.3±3.7 mmHg in nine out of 14 patients that maintaned success. Mean IOP after the last 5-FU injection was 21.4±4.6 mmHg (range, 1335 mmHg). The mean number of 5-FU injections was 2.4 (range, 1 – 6). During a mean follow-up of 25.1 months (range, 1–48 months), three eyes (5.7%) had diffuse corneal punctate epitheliopathy lasting for 3–4 weeks and subconjunctival hemorrhage was seen in nine eyes (17%). Needle revision and/or subconjunctival injection of 5-FU over the bleb area is a safe, relatively efficient approach with a low rate of complications to overcome the early and mid term bleb failure after trabeculectomy.
