Purpose:
To visualize the iridocorneal angle – after the first canaloplasty
procedures performed in Italy – by means of two different
ultrasound biomicroscopy (UBM) units.
Method:
Sixteen eyes of
fifteen patients with primary open angle glaucoma (mean 56, range
25 – 82 years) underwent canaloplasty (12 eyes) or canaloplasty
combined with phacoemulsification (4 eyes). 50 MHz (Paradigm
P45) and 80 MHz (i-UltraSound) UBM examination was performed
1 to 12 (mean 3.7) months after surgery. Results:
Both US systems
could show intrascleral lake and trabecular meshwork (TM) distension
– by a polypropilene suture in Schlemm’s canal – which was
graded as minimal in three eyes (group 1) and good in thirteen eyes
(group 2) according to the higher resolution of 80 MHz images.
Post-operative IOP was significantly (p > 0.0001) different in group 1
(22.5 ± 2.4 mm Hg) and group 2 (16.1 ± 1.9 mm Hg). Intrascleral lake
could be clearly imaged in 33% of group 1 and 100% of group 2
(p > 0.001). The overall qualified success (IOP< 21 mm Hg) of canaloplasty
was 81% and number of IOP lowering medications significantly
(p < 0.001) decreased from 2.2 ± 1.2 preoperatively to
0.8 ± 1.0
postoperatively.
Conclusion: In our experience after canaloplasty 80 but
also 50 MHz technology can show TM distension by
suture tensioning and
intrascleral lake. Both findings are important
for canaloplasty working
mechanism.
