AIM: To evaluate the results of mitomycin-C(MMC)-augmented viscocanalostomy in patients with open-angle glaucoma.<p>METHODS: This retrospective study included 104 patients who underwent viscocanalostomy surgery between December 2007 and March 2014. Pre- and postoperative intraocular pressure(IOP), number of glaucoma medications, visual acuity, complications, adjunctive procedure(laser goniopuncture and/or glaucoma medication), and success rate were recorded. Complete success was defined as IOP≤21 mmHg without additional medication, and qualified success was defined as IOP≤21 mmHg with or without glaucoma medication.<p>RESULTS: Mean preoperative IOP was 27.5±9.2 mmHg and mean postoperative IOP was 14.5±6.6 mmHg at the last visit(<i>P</i><0.001). Mean visual acuity before and after surgery were 0.42±0.4 and 0.32±0.4, respectively(<i>P</i>=0.726). Qualified success was achieved in 106(86.9%)eyes and complete success was achieved in 62(50.8%)eyes. Laser goniopuncture was performed in 43(35.2%)eyes and glaucoma medication usage rate was 49.1%. The mean postoperative followup period was 27.29±16.78(1-79)mo.<p>CONCLUSION:Although viscocanalostomy is a safer option due to low complication rates and stable visual acuity, without laser goniopuncture(LGP), surgical success rate is still very low. Further comparative studies are necessary to evaluate the contribution of MMC to viscocanalostomy surgery.
