Laboratory Studies

Iris prolapse is a clinical diagnosis.

Imaging Studies

In long-standing iris prolapse, if cystoid macular edema is suspected, ocular coherence tomography (OCT) and fluorescein angiography may be performed. Cystoid macula edema appears as intraretinal edema on OCT and flower petal leakage in the macula in the late stages of the angiogram.

CT scan of the orbits is indicated with traumatic iris prolapse to aid in diagnosing other ocular and orbital trauma. CT scan of the orbits may help in localizing intraocular foreign bodies and in assessing the status of the posterior segment of the eye.

In traumatic iris prolapse, ocular ultrasound may be gently performed by experienced personnel. This imaging modality may help to locate intraocular foreign bodies and to assess the status of the posterior segment of the eye. Care should be taken while performing the ocular ultrasound because undue pressure can cause prolapse of the intraocular contents.
