Angle closure glaucoma is a major cause of glaucoma related visual disability worldwide. Plateau iris is one of the causes of angle closure which needs to be kept in mind while dealing with a case of angle closure glaucoma. Plateau iris configuration (PIC) refers to the anatomical configuration of the iris in which iris is inserted anteriorly on the ciliary body. This alters the position of the peripheral iris in relation to the trabecular meshwork, and thus results in narrowing of the angle of the anterior chamber. Plateau iris syndrome (PIS) is defined as persistently narrow angle capable of closure in spite of a patent iridotomy. Here we report a case of 48 years old female who presented with acute angle closure in the Department of Ophthalmology, Dr.RPGMC,Kangra. She was diagnosed as a case of plateau iris syndrome and was managed surgically. Early recognition and intervention are the key components to prevent vision loss in this patient population.
