OBJECTIVE: To evaluate the effectiveness of glaucoma seton implantation surgery via three different pathways for complicated glaucoma. METHODS: Ninety-nine cases (99 eyes) with complicated glaucoma that had undergone glaucoma seton implantation surgery were divided into three groups: 58 cases (58 eyes) were included in the group with anterior chamber implantation (AC group) 16 (16 eyes) in the group with posterior chamber implantation (PC group), and 25 (25 eyes) in the group with vitreous cavity implantation (VC group). RESULTS: The follow-up ranged from six to 34 months (mean, 19.6 months). In the AC group, the postoperative intraocular pressure (IOP) of 40 cases (69.0%) was <21 mmHg (1 mmHg = 0.133 kPa) without using any pressure-lowering agents. The postoperative IOP of six cases (10.3%) was <21 mmHg with pressure-lowering agents. Altogether, there were 46 patients with IOP controlled at <21 mmHg (79.3%). The IOP of 11 cases (68.8%) in the PC group was controlled without agents, and one other case (6.2%) was controlled with medication. Therefore, the total success rate was 75.0% (12 cases). The corresponding rates for the VC group were ten cases (40.0%), three cases (12.0%), and 13 cases (52.0%), respectively. A statistically significant difference (Χ2 = 6.525, p = 0.038) was found in the success rates between these three groups. But, if cases with neovascular glaucoma were excluded, no statistical difference (Χ2 = 4.231, p = 0.121) was seen in the success rates between these three groups. CONCLUSION: No influence on surgical effectiveness was seen between glaucoma seton implantation surgery via different pathways for complicated glaucoma. LA: Chinese
