We calculated the pooled odds ratios（ORs） of COL1A1 rs2075555 polymorphism in high myopia cases vs healthy controls to evaluate the strength of the association.·RESULTS： Overall, there was no significant difference both in the genotype and allele distributions of COL1A1rs2075555 polymorphism between high myopia cases and healthy controls： CC vs AA OR =1.10, 95% confidence interval（CI）=0.76-1.58; AC vs AA OR=0.98, 95%CI 0.80-1.20; CC/AC vs AA/OR=1.01, 95%CI 0.84-1.22; CC vs AC/AA OR =1.06, 95% CI =0.93-1.20; C vs A OR =1.06, 95% CI0.91-1.23）. In addition, in the stratified analyses by ethnicity, no significant associations were found in any genetic model both in European and Asia cohorts.·CONCLUSION： Our results indicate that the COL1A1rs2075555 polymorphism may not affect susceptibility to high myopia.展开更多
