Choroidal detachment and ocular hypotony: CT evaluation.
The computed tomographic (CT) findings in 20 patients with hemorrhagic choroidal detachment, serous choroidal detachment, and/or ocular hypotony are described. Hemorrhagic choroidal detachment appeared as an area of high attenuation that was usually localized, uniformly hyperdense, and not position-dependent (i.e., there was no shift with changing patient position). Serous choroidal detachment appeared as a convex, thick line of increased density within the vitreous cavity. Inflammatory choroidal detachment produces a diffuse intrauveal and suprachoroidal accumulation of high-density, position-dependent fluid, and uveoscleral thickening and enhancement, which in cross section resembles a ring. On CT ocular hypotony produces a characteristic uveoscleral infolding. CT has proved valuable in localizing and differentiating serous or hemorrhagic choroidal detachment and uveoscleral infolding.
