WebIOP is normal, there are no acquired adhesions between the iris and angle structures (peripheral anterior synechiae [PAS]), and no evidence of optic nerve damage. Primary Angle Closure (PAC): is the second stage in which the IOP is elevated and/or PAS are present. There is no evidence of glaucomatous optic neuropathy at this stage. WebOn gonioscopy, the angle is narrow, and peripheral anterior synechiae (adhesions between the peripheral iris and angle structure causing blockage of trabecular meshwork and/or ciliary body face), also called peripheral anterior synechiae (PAS), may be seen.
