title: [The role of choroidal thickness change in acute attack of primary angle closure glaucoma].
abstract: The mechanism of acute attack of primary angle closure glaucoma is unclear. Several studies showed that choroidal thickness was thicker in acute attack eyes than in follow eyes and normal eyes. However, these results are not enough to support the point that choroidal thickness increase is the cause for acute attack of primary angle closure glaucoma. Narrow anterior chamber angle, shallow anterior chamber are risk factors for primary angle closure glaucoma. Dynamic changes of iris, cilliary body crystalline lens and choroid all have effect on the angle width. They could contribute to the acute attack of angle closure. Thus, the acute attack of primary angle closure glaucoma should be the results of interaction effect of multiple risk factors. (Chin J Ophthalmol, 2016, 52: 404-406).
