[Effect of anatomic features of ciliary body on primary angle closure].

The mechanisms of primary angle closure are complex and varied. It is well known that the anatomic features of iris and lens may have influence on the presence of angle closure. However, the effect of structural features of ciliary body on primary angle closure remain unclear yet. The anterior situation of ciliary processes was extensively proved to be one of the predisposing factors of angle closure. While it's still controversial how the thickness of ciliary body may affect angle closure. Recent researches found that primary angle closure was associated with thinner ciliary body thickness. This review is aimed at introducing current researches of the effects of ciliary processes position and ciliary body thickness on primary angle closure. (Chin J Ophthalmol, 2018, 54: 716-720).
