[Risk factors of primary angle closure glaucoma].
Primary angle closure glaucoma is one of the common diseases causing blindness. The pathogenesis inducing primary angle closure glaucoma has not been entirely clear. Traditionally identified risk factors include shallow anterior chamber, short axial length and thicker lens. Recent studies begin to pay attention to other new risk factors, not only including static anatomical factors, such as anterior chamber volume, iris curvature and lens vault, but also including dynamic changing factors, such as dynamic dilation of iris volume and choroidal effusion. Comprehensive assessment of these risk factors is of great significance for early diagnosis and treatment of angle closure glaucoma. This article briefly reviews research advances in risk factors of primary angle closure glaucoma.
