In simple words: Plateau iris syndrome is a condition that can occur after an iridectomy (surgical removal of part of the iris). It happens when parts of the eye called the ciliary processes are in the wrong position, causing pressure to build up in the eye even though part of the iris has been removed. It can appear similar to other eye conditions and needs specialized diagnosis.

Plateau iris syndrome (post-iridectomy) (postprocedural). This condition is characterized by anteriorly positioned or rotated ciliary processes that result in angle closure despite an iridectomy. It is often confused with pupillary block or aqueous misdirection.

Example 1: A patient presents with elevated intraocular pressure, despite having previously undergone an iridectomy. Gonioscopy reveals anteriorly positioned ciliary processes, leading to the diagnosis of plateau iris syndrome., Following cataract surgery and an iridectomy, a patient develops recurrent episodes of increased eye pressure, accompanied by mild pain and blurred vision. The diagnosis of plateau iris syndrome is confirmed after careful examination and ruling out other causes., A patient with a history of plateau iris syndrome managed with medication requires laser iridoplasty to address recurrent angle closure despite ongoing medical therapy.

Documentation should include a detailed history of the present illness, past ocular surgeries (including iridectomy), gonioscopy findings demonstrating anteriorly positioned or rotated ciliary processes, intraocular pressure measurements, and response to any prior treatments. Differential diagnosis considerations should also be documented, including pupillary block glaucoma and aqueous misdirection.
