PURPOSE: To determine the role of the choroidal vasculature in the pat
hogenesis of exudative retinal detachments in preeclampsia using indoc
yanine green angiography. METHODS: We reviewed both fluorescein and in
docyanine green angiographic findings for four patients with preeclamp
sia. RESULTS: Indocyanine green angiographic findings in patients with
preeclampsia include nonperfusion in the early phases of the angiogra
m and staining of the choroidal vasculature with subretinal leakage in
the late phases of the angiogram and multiple punctate areas of block
ed fluorescence. CONCLUSION: Indocyanine green angiography indicates t
hat damage to the choroidal vasculature leads to many of the retinal c
hanges seen in preeclampsia.
