[Mitomycin C in open angle glaucoma surgery with previous failed glaucoma surgery].

PURPOSE: This study investigates the results of trabeculectomy with peroperative topical application of mitomycin-C performed on eyes with previous failed glaucoma filtering surgery. METHODS: The study includes 34 eyes of 26 patients operated on open angle glaucoma between March 1992 and October 1996, with a minimum of 6 months follow-up (mean 28.1 months). All the eyes had undergone prior one (27) o two (7) filtering surgeries. We evaluated intraocular pressure (IOP) and treatment reduction after surgery. Success was defined as IOP <20 mmHg, without deterioration of the visual field and/or papilla and without oral carbonic anhydrase inhibitors (OCAI) treatment. RESULTS: Average IOP decrease (p<0,001) from 21.06+/-3.70 mmHg to 13.88+/-2.42 mmHg after surgery and the number of medications dropped from 2.44+/-0.69 to 0.68+/-1.02 (p<0.01). The success rate was 88.2%. The major complication was hypotony maculopathy in 3 eyes (8.8%). CONCLUSIONS: Trabeculectomy with mitomycin-C decreases IOP and postoperative medications in eyes with previous unsuccessful filtering surgery.

[The Ahmed valve implant in complicated glaucoma].

PURPOSE: Prospective study initiated in September of 1994 in patients with complicated glaucoma who had had the Ahmed valve implanted. METHODS: 12 eyes from 12 patients were studied until February of 1996, with a median follow-up of 9.3+/-5.1 months (range 3-18 months). The most common diagnostic was pseudophakic glaucoma (8 ojos). 3 eyes had aphakic glaucoma and 1 eye had traumatic glaucoma. The success is defined as intraocular pressure (IOP) </=20 mmHg. without oral carbonic anhydrase inhibitors (OCAI) treatment. RESULTS: The IOP was reduced (p<0.01) of 26.2+/-9.96 mmHg to 15.7+/-4.48 mmHg. The success was of 83.3% but only 2 eyes (16.6%) were controlled effectively without treatment. The major complication was the Tenon's cyst (25%). CONCLUSIONS: From the percentage of successes (83.3%) and the absence of important complications we advise the implantation of the Ahmed glaucoma valve in those patients with complicated glaucoma after a failure of filtrating surgery with mitomycin-C.
