Long-term Follow-up Results of Glaucoma Triple Procedures in Patients with Angle-closure Glaucoma

PURPOSE: To evaluate the long-term clinical efficacy for glaucoma triple procedures of angle-closure glaucoma. METHODS: The author reviewed retrospectively 30 eyes (Group A) which had undergone triple procedures for coexisting angle-closure glaucoma and cataract. The results were compared with those of 30 eyes (Group B) which had undergone trabeculectomy for angle-closure glaucoma and 25 eyes (Group C) which had undergone glaucoma triple procedures for open-angle glaucoma. All patients were followed up for more than 3 years after operation at the Department of Ophthalmology in a hospital from November 1990 to December 1999. RESULTS: The mean intraocular pressures at the last follow-up were 16.1mmHg, 20.9mmHg and 19.7mmHg and the surgical success rates were 83.3%, 63.3% and 68.0% in the triple procedure group of angle-closure glaucoma, trabeculectomy-alone group and triple procedure group of open-angle glaucoma respectively. CONCLUSIONS: Triple procedures in angle-closure glaucoma showed good long-term results in IOP control compared with the trabeculectomy-alone group in angle-closure glaucoma.

Clinical Comparison between Glaucoma Triple Procedure and Small Incision Cataract Surgery using Foldable silicone IOL

The purpose of this study was to evaluate the postoperative outcomes between the glaucoma triple procedure and the small incision cataract surgery using foldable silicone intraocular lens(IOL). This prospective randomized study comprised of 42 eyes which had the glaucoma triple procedure and 41 eyes which underwent small incision cataract surgery at chonnam University Hospital from May, 1994 to December, 1996. At least 3 months follow-up period was needed. Corrected visual acuity of 0.5 of better was obtained in 50% of triple procedure group and 88% of small incision cataract surgery group with the average lines of improved visual acuity of 5.6 and 7.2 respectively. There was no significant change in the refractive cylinder during the early postoperative period in both group. In the glaucoma triple procedure group, posterior capsular opacification(PCO) developed in significantly low incidence in the Mitomycin C using group and the incidence of PCO in eyes with IOL decentration was greater than in those without IOL decentration. In conclusion, patients who underwent glaucoma triple procedure using foldable silicone IOL showed excellent postoperative IOP control with success rate of 81%, rapid visual rehabilitation and refractive stability. We also found that glaucoma triple procedure with Mitomycin C was associated with lower incidence of PCO.
