Peripheral anterior synechiae (PAS) are adhesions of the peripheral iris to the structures in the angle of the anterior chamber. They may be associated with a variety of conditions such as angle closure glaucoma, neovascular glaucoma, uveitis, and iridocorneal endothelial (ICE) syndrome.

This series of images was obtained in a 30-year-old female who presented for evaluation of an abnormal pupil and was subsequently diagnosed with iridocorneal endothelial (ICE) syndrome.
