Choroidal detachment and ocular hypotony: CT evaluation
MF Mafee and GA Peyman
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.
