Iridoschisis associated with nanophthalmos and bullous keratopathy.

Iridoschisis is a rare condition in which the iris stroma splits into anterior and posterior layers. Iridoschisis is associated with anterior segment abnormalities including keratoconus, lens subluxation and angle-closure glaucoma. We describe the first case in which iridoschisis has occurred in association with nanophthalmos. We also report the rare complication of irido-corneal touch and subsequent corneal decompensation. Nanophthalmos and irido-corneal touch are sight-threatening associations of iridoschisis and should be excluded in all patients with this rare condition.
