Purpose
To assess the safety and efficacy of gonioscopy-assisted transluminal trabeculotomy (GATT) in the treatment of primary congenital glaucoma (PCG).
Setting
Cairo University Pediatric Ophthalmology & Strabismus Unit.
Methods
This prospective interventional study included 43 eyes of 31 patients aged <12 years diagnosed with PCG. Patients underwent GATT using 5/0 prolene suture. We excluded patients that had <270 degrees of the angle incised and those who did not complete 24 months' follow-up.
Results
The mean intraocular pressure (IOP) decreased from 23.4mmHg to 13.1, 12.7,13.5,11.9 & 11.2 mmHg at 1,3,6,12 & 24 months postoperatively (p<0.001 at all postoperative follow-ups). There was a statistically signficant reduction in mean post operative IOP lowering drugs from 0.77 to 0.4 at final follow up (p<0.05). Six eyes (13.9%) required additional glaucoma surgeries during the first year and two eyes (4.6%) failed to achieve > 20% IOP reduction. All other eyes had a final IOP of <18 mmHg, with 32 eyes (74.4%) being controlled without medications. No major complications occurred, except for early transient postoperative hyphema in 15 eyes (34.8%) which resolved spontaneously within 2 weeks and required no intervention.
Conclusions
GATT using a 5/0 prolene suture is a fast, safe minimally-invasive procedure that yields a high success rate in PCG patients for up to two years post-operatively.
