• Trabeculectomies were performed on 15 eyes because of uncontrolled glaucoma despite the maximum use of tolerated antiglaucoma medication. We considered all of these eyes to be at increased risk for episcleral cicatricial closure for one of the following reasons: neonatal glaucoma, a patient of age 40 years or less, previously failed glaucoma filtration surgery, or aphakia. A standard operation was performed except that triamcinolone acetonide (4 mg) was injected subconjunctivally at the intended trabeculectomy site one week before surgery in 12 eyes, the day of surgery in two eyes, and two days prior to surgery in one eye. During the follow-up period of six to 16 months, 14 of 15 eyes had an intraocular pressure (IOP) of 18 mm Hg or less. The average IOP for these 14 eyes was 12.4 ± 4.6 (mean ± 1 SD), and only three of the 14 required any antiglaucoma medication. One eye was a surgical failure. All eyes with controlled IOP had diffuse microcystic filtration blebs by slitlamp examination. The postoperative visual acuity was within one line of the preoperative level in all eyes, except for the one failure. The use of triamcinolone did not appear to add any additional risks to the surgical procedure or to the postoperative period.
