Angle closure in pseudophakic eyes is uncommon and its mechanism varies. Inflammation with posterior synechiae, zonular disruption with vitreous prolapse, and ciliary block with aqueous misdirection may predispose to angle closure and elevated intraocular pressure.

Proliferation of the remaining lenticular epithelial cells after cataract extraction may form a circumferential structure at the level of the lens (Soemmering ring). This typically benign structure has been reported to cause pupillary block, leading to angle closure.1 We describe a patient who had progressive synechial angle closure without pupillary block, due to an enlarging Soemmering ring after phacoemulsification.
