Multifactor conditional logistic regression analysis showed five variables associated with the onset of PACG (P<0. 05), including the place of residence, long time use the eye, hyperopia and asthenopia, family relationship.?CONCLUSION:PACG is affected by various pathogenic factors, and it is helpful to analyze risk factors to reduce the incidence of PACG.
