* BACKGROUND AND OBJECTIVE: To report the results of trabeculectomy with adjunctive intraoperative mitomycin C in Chinese patients with glaucoma.
* PATIENTS AND METHODS: The medical records of Chinese patients who received trabeculectomy with intraoperative mitomycin C from 1992 to 1998 were retrospectively reviewed. A "successful" trabeculectomy was defined as one after which the intraocular pressure (IOP) could be controlled to between 5 and 21 mm Hg, inclusive, with no more than 3 glaucoma medications.
* RESULTS: One hundred fourteen trabeculectomies in 105 eyes of 90 patients were retrospectively reviewed. Mean age ± standard deviation was 48.1 ± 21.9 years. Primary open-angle glaucoma (43.0%) and angle-closure glaucoma (27.2%) were the most common diagnoses leading to trabeculectomy. The mean follow-up ± standard deviation was 29.6 ± 18.6 months (range, 6 to 92 months). The overall success rate at the last followup was 73.7% (84 of 114 trabeculectomies).
* CONCLUSIONS: Trabeculectomy with mitomycin C is a safe and effective procedure for the control of IOP in Chinese patients with glaucoma.

Background
To determine the association of the ANGPT2 gene with primary open-angle glaucoma (POAG) in Chinese.
Methods
Six single-nucleotide polymorphisms (SNPs) in ANGPT2 (rs2515487, rs2922869, rs13255574, rs4455855, rs13269021, and rs11775442) were genotyped in a total of 2601 study subjects from two cohorts. One is a Hong Kong Chinese cohort of 484 high tension glaucoma (HTG) and 537 normal tension glaucoma (NTG) patients, and 496 non-glaucoma control subjects. Another cohort is a Shantou Chinese cohort of 403 HTG and 135 NTG patients, and 543 non-glaucoma control subjects. Subgroup analysis by sex was conducted. Outcomes from different cohorts were combined for meta-analysis.
Results
The association of SNP rs11775442 with NTG in the Hong Kong cohort [P = 0.0498, OR = 1.24, 95% confidence interval (CI) 1.00–1.55] after adjusting for age and sex did not reach statistical significance after Bonferroni correction. Other SNPs were not significantly associated with NTG, HTG and POAG in individual cohort or in the combined analyses (P > 0.05). In the subgroup analysis by sex, SNP rs13269021 in the Shantou cohort, but not in the Hong Kong cohort, was significantly associated with NTG in males (P = 0.0081, OR = 1.67, 95% CI: 1.14–2.43) but not in females (P = 0.874). In the combined analyses by sex, no SNPs were significantly associated with NTG, HTG and POAG.
Conclusions
In the subgroup analysis by sex, a significant association was shown in SNP rs13269021 with NTG in Shantou males, but not in Hong Kong males. Further studies are needed to verify the association between ANGPT2 locus (rs13269021) and NTG in Chinese males.
