  • Title: Deep sclerectomy with mitomycin C in failed trabeculectomy.
    Author: Rebolleda G, Muñoz-Negrete FJ.
    Journal: Eye (Lond); 2007 Jan; 21(1):23-8. PubMed ID: 16311522.
    Abstract:
    AIM: To evaluate the success rate and complications associated with deep sclerectomy with mitomycin C (MMC) and a reticulated hyaluronic acid implant in previously failed trabeculectomy. METHODS: This prospective study included 20 eyes with a previously failed trabeculectomy, which were treated with deep sclerectomy with 0.2 mg/ml MMC application under the conjunctiva and superficial scleral flap. Intraocular pressure (IOP), glaucoma medications, visual acuity, and complications were recorded preoperatively and 1 day, 1 week, and 1, 3, 6, and 12 months postoperatively. RESULTS: The mean preoperative IOP was 25.8+/-7.3 mmHg; the IOP significantly decreased to 14.6+/-3.2 mmHg 1 year postoperative. At each interval, the mean IOP was significantly lower than preoperatively (P=0.000). At 1 year, the complete success rate (IOP<or=21 mmHg untreated) was 65% and the qualified success rate (IOP<or=21 mmHg with and without medication) was 100%. 12 patients (60%) achieved an IOP<or=15 mmHg with and without medication. No shallow or flat anterior chamber, endophthalmitis, or leakage developed. CONCLUSIONS: These data suggest that deep sclerectomy augmented with MMC is a safe surgical procedure that decreases IOP in eyes with a previously failed trabeculectomy.
