METHODS: Retrospective analysis of improved viscocanalostomy was performed on 51 eyes of 42 patients with primary congenital glaucoma. The outcome evaluation included postoperative intraocular pressure (IOP), corneal diameter, cup/disc ratio and complications. All patients were followed up at week 1, month 1, 3, 6 and 12. RESULTS: The results revealed that postoperative IOP was decreased from (38.57 +/- 13.61)mmHg to (10.53 +/- 3.91)mmHg. (14.89 +/- 5.26)mmHg,(15.42 +/- 5.11)mmHg, (13.82 +/- 3.46)mmHg, (13.16 +/- 5.29)mmHg at follow-up time of 1 week,1, 3, 6, 12 months (P<0.001). The postoperative corneal diameter was decreased significantly (P=0.002); The mean cup/dish ratio wasn't significantly different (P=0.148) before and after the surgery, the cup/dish ratio of successful surgery was evidently decreased (preoperative 0.7 +/- 0.2, postoperative 0.6 +/- 0.3, P = 0.007), but the complications like unformed anterior chamber were not observed. The mean follow-up period was 12 months. CONCUJSION: Improved viscocanalostomy improves the clinical effects of the patients with primary congenital glaucoma, such as higher success rates, lower postoperative mean IOP and fewer complications.展开更多

This study aimed to compare the efficacy and safety between viscocanalostomy and mitomycin C (MMC)-trabeculectomy in patients with PCG. Methods A total number of 43 patients with PCG who underwent either viscocanalostomy (group 1) or MMC- trabeculectomy (group 2) between June 2003 and June 2008 were retrospectively reviewed. The patients' intraocular pressures (lOPs) were examined before surgery and on day 1, week 1, month 1, month 6, and month 12 post-operative. Mean horizontal corneal diameters, success rates, intra- and post-operative complications were compared between the two groups. Results Pre-operative lOPs were (31.96±3.90) mmHg in group 1 and (32.56±4.00) mmHg in group 2. At the last visit, lOPs were (16.78±2.20) mmHg and (15.77±2.60) mmHg, respectively (P 〈0.001); the complete success rates of group 1 and group 2 were 45.9% and 67.4%, respectively, and the difference was not statistically significant (P=0.158). There were no major complications occurred in the two groups. Conclusions Both viscocanalostomy and trabeculectomy can lower lOP in PCG patients effectively. Although there was no major complications occurred in both groups, viscocanlostomy may decrease the probability of postoperative haemorrhage, hypotony, cataract, or choroid effusion.展开更多
