Supraciliary effusion
Accumulation of fluid in the supraciliary space, typically occurring after intraocular surgery and causing anterior chamber shallowing.
Full Definition
Supraciliary effusion refers to the abnormal accumulation of serous fluid in the potential space between the ciliary muscle bundles and the sclera. This condition most commonly occurs following intraocular surgery, particularly in patients with pre-existing glaucoma or those undergoing filtration procedures. The effusion causes forward rotation of the ciliary body, leading to anterior chamber shallowing, angle closure, and potential secondary glaucoma. Ultrasound biomicroscopy is the diagnostic modality of choice for identifying supraciliary effusions. Treatment typically involves cycloplegic agents to relax ciliary muscle tension, anti-inflammatory medications, and occasionally surgical drainage in severe cases. Prompt recognition and treatment are essential to prevent permanent angle damage and vision loss.
Usage
Usage note: Often confused with choroidal effusion; supraciliary location is confirmed by ultrasound biomicroscopy showing fluid anterior to ciliary muscle.
