[A case-control study of factors associated with primary angle-closure glaucoma].
OBJECTIVE
To understand the risk factors of primary angle-closure glaucoma.


METHODS
One to one matched case-control study was conducted in this study. One hundred and ninety two PACG cases and 192 controls, matched by age and gender, were collected from Department of Ophthalmology, Affiliated Hospital of Nantong University. All of the participants were investigated for their demographic information, behavioral habits, disease history, glaucoma family history and received clinical ocular examinations. The difference between these two groups was analyzed.


RESULTS
Several factors, including hypertension (OR = 2.004, P = 0.009), glaucoma family history (OR = 6.726, P = 0.003), presbyopia (OR = 3.192, P = 0.031), shallow anterior chamber (OR = 12.804, P = 0.000) and high cup-to-disc ratio (OR = 9.401, P = 0.007) were associated with PACG by multiply Logistic regression. The results did not support that smoking, drinking, myopia, diabetes mellitus and blood style were related to PACG.


CONCLUSIONS
Follow up the populations with glaucoma family history, shallow anterior chamber or high cup-to-disc ratio are the main procedures for the decrease of incidence of PACG.
