To evaluate the long-term results of viscogoniotomy and goniotomy, and to compare the success rates and complications of these two techniques.


Patients who had undergone surgery for primary congenital glaucoma were divided into two groups. Group 1 consisted of 38 eyes of 21 patients who underwent classical goniotomy and group 2 consisted of 44 eyes of 25 patients who underwent viscogoni-otomy. Pre-and postoperative intraocular pressures (IOPs), mean antiglaucoma medication, me-an corneal diameter, success rates, intra-and postoperative complications were compared betwe-en two groups.


Mean preoperative IOP was 28.9±3.6 mmHg in group 1 and 29.3±2.8 mmHg in group 2. At the last visit, it was 17.3±3.1 mmHg and 16.2±2.1 mmHg, respectively (P<.001). The mean number of antiglaucoma medications used after surgery was significantly lower in both groups (for each, P<.001). The success rates at the last visit of group 1 and group 2 were 68.4% and 88.6%, respectively, and there was statistically significant difference between two groups (P<.05). The most common early postoperative complication was hyphema in group 1 and transient IOP elevation in group 2.


Use of viscoelastic materials during goniotomy surgery increase the success rate and decrease complications rate by preventing hyphema and formation of flat anterior chamber.
