Plateau iris
Plateau iris is a less common medical condition of the eye resulting from anterior displacement of the peripheral iris by the ciliary body causing angle closure glaucoma. First line treatment for all causes of narrow angle glaucoma is laser iridotomy. If narrow angle glaucoma persists after iridotomy then it is called plateau iris syndrome and subsequently managed either medically (miotics) or surgically (laser peripheral iridoplasty). Plateau iris is a less common form of narrow angle glaucoma and is sometimes discovered after an iridotomy causes a rapid increase in eye pressure. Since this condition is not common, most ophthalmologists are unfamiliar with, and have little experience with, the anatomy of and treatments for this condition.
