253 Sclerothalamotomy (STT) ab interno, une nouvelle méthode minimale invasive chirurgical du glaucome, 4 ans de “follow-up”

Abstract

Aim The aim of this study is to demonstrate the efficacy and safety of a new surgical procedure termed sclerothalamotomy ab interno (STT ab interno ) for the treatment of primary open-angle glaucoma and juvenile glaucoma. Aim and Methods 58 non penetrating glaucoma procedures called “sclerothalamotomies ab interno ” were performed with radiofrequency in 53 patients with primary open-angle glaucoma and 5 patients with juvenile glaucoma between April 2002 and June 2003. The average preoperative intraocular pressure (IOP) in the 53 primary open-angle glaucoma respectively 5 juvenile glaucoma patients was 25.6 ± 2.3 mmHg respectively 41.0 ± 6.4 mmHg. The sclerothalamotomies ab interno were carried out with a custom made high-frequency dissection 19G probe (tip 0.3 × 1 mm) applying bipolar current with a frequency of 500 kHz. Discussion After a follow-up period of 48 months, the average IOP dropped to 14.6 ± 1.7 mmHg respectively to 12.0 ± 2.6 mmHg, an outcome which is in both groups statistically (p Conclusion Sclerothalamotomy ab interno is a minimally invasive, safe and efficacious surgical technique for lowering IOP in open-angle and juvenile glaucoma.
