High Frequency Color Doppler Image of Choroidal Detachment

摘要

Purpose:To study the Color Doppler Image(CDI)characteristics of choroidal detachment and the applied valus of CDI.Methods:Seventy-two cases(74eyes)of choroidal edtachment were studied retrospectively.Results:The typical ultragraph of chororidal detachment displayed one or several smooth hemispherical or lobuler circular thick bands,with convex side toward vitreous cavity,Most of the choroidal detachments were located before the equator,a few of them were beyond the equator.CDI displayed blood flow singnal in the band.Pulse Doppler showed the frequency spectrum features of retinal detachment band were similar to those of central retinal vessels,whereas the frequency spectum features of choroidal detachment bend resembled those of ciliary artery in some cases of retinal detachment(RD)accompanied by choroidal detachment.Conclusion:CDI could make a correct and precise diagnosis of choroidal detachment.Eye Science2000;16:61-64.
