Primary angle-closure glaucoma(PACG)is the most common type of glaucoma in clinical. It is characterized by progressive and irreversible development with high global incidence and high possibility of blindness. The pathogenesis of PACG is complicated. It is not only associated with the abnormality of the ocular anatomy, such as the small cornea, short eye axis and shallow anterior chamber, but also found that the abnormality of the lens, iris, ciliary body and choroid are related to the pathogenesis of PACG in recent years. Moreover, the occurrence of PACG is also closely related to genetic and psychological stress factors. Our study summarized some literatures and made a brief discussion on the pathogenesis of PACG from the three aspects of anatomical characteristics, genetic factors, and psychological stress. We hope to provide useful theoretical support for the early diagnosis and treatment of glaucoma.
