Abstract
Purpose :
To evaluate the effectiveness and safety of microcatheter-assisted trabeculotomy to treat primary congenital glaucoma (PCG) after failed glaucomasurgeries.
Methods :
Eyes of consecutive patientswith PCG after failed glaucoma surgeries who underwent microcatheter-assisted trabeculotomy from February 2014 to June 2016 werereviewed. Baseline characteristics, time to failure or lastvisit, surgical details, final intraocular pressure (IOP),and complications were recorded. Success was defined as final IOP of 21 mmHg or less, with anti-glaucoma medications (qualified success) and without (complete success).
Results :
Seventy-four eyes of 63 patientswere included. Mean follow-up period is29.6±8.2 months.Average numberof previous surgeries for all the eyes was 1.7 ± 1.1 including angle surgeries and filteringsurgeries. Fifty (67.6%) eyes achieved a completeor a partial 360°trabeculotomy using the microcatheter.Mean IOP decreased from 35.3±7.2 mmHg on 2.7±0.8 medications preoperatively to 17.7±8.6 mmHg on0.6±1.2 medications at the last postoperative follow-up (P＜0.001).Cumulative probabilities of qualified andcompletesuccesswere 84.0%and80% both at 1 year and 3year.Complications were minimal.
Conclusions :
Microcatheter-assisted trabeculotomy achieved significant pressure lowering effects for selectedcases of PCG with previous failed glaucoma surgeries and no significant complications.
