title: [Choroidal venous dilatation in serous retinal detachment].
abstract: We studied the correlation between choroidal venous dilatation, intrachoroidal leakage of dye, and subretinal leakage from the choroid in patients with serous retinal detachment unaccompanied by choroidal neovascularization. We reviewed 13 eyes with anamnesis of serous retinal detachment, 23 eyes without anamnesis, and one eye of unknown status of a total of 37 eyes. Regarding the relationship between subretinal dye leakage from the choroid in fluorescein angiography (FAG) and choroidal venous dilatation in indocyanine green angiography (ICG), the point of subretinal leakage (31 points) was on and/or in the neighborhood of the site of choroidal venous dilatation in 87.1% of the 27 eyes, except for eyes of unknown site of leakage in FAG. The point of subretinal leakage was within and/or in the neighborhood of the intrachoroidal leakage of dye in ICG in 92% of the eyes. In serous retinal detachment without choroidal neovascular membranes, serous retinal detachment may be caused by breakdown of the outer retinal barrier due to choroidal venous congestion and intrachoroidal diffusion.
