| Abstract |
|
In eyes with media opacity and equivocal ultrasonographic findings, we can differenciate retinal detachment from vitreous membrane using color doppler imaging(CDI), which allows the display of blood flow characteristics on conventional ultrasonography. The authors performed high resolution Bscan ultrasonography and color doppler imaging simultaneously in 31 eyes with opacity of ocular media, and their intraoperative characteristics and post operative results were evaluated. In 30 eyes with retinal detachment or vitreous membrane, 7 eyes(23%) had equivocal ultrasonographic findings and needed color doppler imaging. Nine eyes(75%) had positive color signal in 12 eyes with retinal detachment, whereas 3 eyes negative. 17 eyes(94%) had negative color signal in 18 eyes with vitreous membrane, 1 eye with proliferative diabetic retinopathy had positive. In conclusion, color doppler imaging is a useful diagnostic method in differentiating retinal detachment from vitreous membrane. |
