目的：通过问卷分析探讨原发性闭角型青光眼(primary angle-closure glaucoma，PACG)发病的危险因素。

方法：本研究通过1：2匹配病例对照，选取2015-01/2017-01在郴州市湘南学院附属医院眼科住院的原发性闭角型青光眼30例和同院其他与青光眼无共同致病因素的患者60例，进行回顾性病例对照研究。

结果：运用SPSS17.0软件进行统计分析，单因素Logistic回归分析显示居住农村、较低文化水平、高血压、用眼时间长、远视、视力疲劳、家庭关系不和谐、家庭成员有患病8个变量与PACG发病有关。多因素条件Logistic回归分析进一步表明：居住地、用眼时间、远视、视力疲劳、家庭关系5个变量是PACG发病的独立危险因素。

结论：原发性闭角型青光眼受多种致病因素的影响，分析其致病因素有利于降低原发性闭角型青光眼的发病率。

METHODS: By 1:2 matched case-control study, we selected 30 primary angle-closure glaucoma in Department of Ophthalmology, Affiliated Hospital of Xiangnan University from January 2015 to January 2017 and other 60 cases, the latter were no common pathogenic factors of glaucoma.

RESULTS: Using SPSS 17.0 software for statistical analysis, single factor logistic regression analysis showed that living in rural areas, the low cultural level, high blood pressure, long time use the eye, hyperopia and asthenopia, disharmony of family relationship, family members with glaucoma were eight variables associated with the onset of PACG. 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.
