Abstract
Purpose :
To compare microcatheter-assisted trabeculotomy with standard rigid probe trabeculotomy for the treatment of childhood glaucoma
Methods :
The early postoperative (12 months) results of microcatheter-assisted trabeculotomy (group 1) were retrospectively compared with those of rigid probe trabeculotomy (group 2) in patients treated for childhood glaucoma. Success was defined as an intraocular pressure (IOP) <21 mmHg with at least a 30% reduction from preoperative IOP with (qualified success) or without (complete success) the use of anti-glaucoma medication.
Results :
A total of 43 eyes of 36 patients were included. Mean IOP in group 1 was significantly lower than that in group 2 at 6 month (17.0±5.1 vs. 22.5±9.8; P=0.037), at 9 months (16.3±5.0 vs.21.6±9.6; P=0.007) and at 12 months (14.8±2.5 vs.19.0±7.1; P=0.041) postoperatively. The mean percentage reduction in IOP from preoperative to the last postoperative follow-up was greater in group 1 (47.3±17.7%) than in group 2 (34.2±21.9%) (P=0.036). Group 1 demonstrated an 81.0% complete and 86.4% qualified success rate, exceeding the 51.6% complete (P=0.060) and 61.9% qualified (p=0.037) success rate of group 2. There were no long-term complications in either group, but choroidal detachment occurred in one eye in group 2.
Conclusions :
Microcatheter-assisted circumferential trabeculotomy provide stronger pressure lowing effect compared with traditional trabeculotomy with rigid probe, and had minimal complications in the early postoperative course.
