Other related information

Consecutive patients that underwent trabeculectomy or phacotrabeculectomy with mitomycin C were evaluated. Flat anterior chamber was divided into three grades. Incidence of flat anterior chamber was evaluated. Risk factor for flat anterior chamber was analyzed by logistic regression model. To identify the hazards rations for the failure of trabeculectomy for 5 years, multivariate Cox proportional hazards regression analysis was performed.
