Sclerothalamectomy: atable postoperative intraocular pressure in primary open-angle and pseudoexfoliative glaucoma
Pallas G; Pajic BKlinische Monatsblätter für Augenheilkunde 2000; 216: 256-260
BACKGROUND: Since the 1970s the authors have operated on hemorrhagic glaucoma using ciliary body exposure after Benedikt. In a few patients they noted stable intraocular pressure regulation for years, often in these cases where there was no filtering bleb. This signifies that the ciliary body is heavily involved in resorption of the anterior chamber fluid. During the following years, they developed this operating technique further and successfully use it today in the operative treatment of primary open-angle and pseudoexfoliative glaucoma. PATIENTS AND METHODS: Since March 1996, the authors have performed sclerothalamectomy in 46 eyes. In approximately half these cases, the operation was combined with cataract surgery. Twenty-seven eyes had primary open-angle and 19 eyes pseudoexfoliative glaucoma with a mean preoperative intraocular pressure of 29.79 ± 7.96 mmHg and 33.58 ± 9.32 mmHg, respectively. RESULTS: The mean follow-up was 18.3 ± 8.9 months (mean, 20) in the case of primary open-angle glaucoma, and 15.8 ± 11 (mean, 16) months in the case of pseudoexfoliative glaucoma. The mean postoperative intraocular pressure, which in the primary open-angle glaucoma group was 13.9 ± 1.6 mmHg and in the pseudoexfoliative glaucoma group 12.9 ± 2.5 mmHg, was significantly lower with significantly less postoperative medication compared to the preoperative values during the entire follow-up (p < 0.01). There was no evidence of a significant difference between the groups regarding postoperative complications or intraocular pressure. The authors observed a total of seven eyes with a flat filtering bleb, 5/27 in the primary open angle glaucoma group and 2/19 in the pseudoexfoliarive glaucoma group. CONCLUSIONS: Sclerothalamectomy leads to long-term stable intraocular pressure with a low complication rate in the case of primary open-angle and pseudoexfoliative glaucoma. LA: German
