PURPOSE: To compare the success and complication rates of viscogoniotomy and goniotomy in Turkish patients. METHODS: In a retrospective review, the medical records of patients with primary congenital glaucoma were divided into two groups. Group 1 consisted of 21 patients (38 eyes) who had undergone classical goniotomy, and group 2 consisted of 25 patients (44 eyes) who had undergone viscogoniotomy. The success rates and intra- and postoperative complications were compared between the two groups. RESULTS: Mean preoperative introcular pressure (IOP) was 28.9 ± 3.6 mmHg in group 1 and 29.3 ± 2.8 mmHg in group 2. At the last postoperative visit, it was 17.3 ± 3.1 mmHg and 16.2 ± 2.1 mmHg, respectively (P < 0.001). The success rates at the last visit of group 1 and group 2 were 68.4% and 88.6%, respectively (P < 0.05). The most common early postoperative complication was hyphema in group 1 and transient IOP elevation in group 2. CONCLUSION. Viscogoniotomy may increase the success rate and decrease the complications rate by preventing hyphema and flat anterior chamber.
