choroidal effusion
Accumulation of fluid in the supraciliary and suprachoroidal spaces, causing choroidal detachment.
Full Definition
Choroidal effusion occurs when fluid accumulates in the potential space between the choroid and sclera, causing the choroid to separate from the scleral wall. This condition can result from hypotony, inflammation, surgical trauma, or increased episcleral venous pressure. The effusion appears as a dome-shaped elevation of the choroid and can be serous or hemorrhagic. Surgical management may include drainage through sclerotomy if conservative treatment fails, particularly when the effusion is extensive and affects visual function or causes persistent hypotony.
Usage
Usage note: Often occurs as a complication of hypotony. Specify location (anterior vs posterior) when relevant.
