Abstract:
Objective To investigate value of color Doppler flow imaging(CDFI) and Doppler power imaging(CDPI) in the diagnosis of choroidal detachment(CD). Methods Color Doppler ultrasound was performed in 30 cases with choroidal detachment. At the base of eyeball shape, lens, vitreous and retina examined by ultrasound, intraocular band-shaped echo was examined by CDFI and CDPI, to understand its blood flow. The observation was compared with that of surgical results. Results Of 30 cases with choroidal detachment, the diagnostic positive correspondonce of ultrasound was 80.0%, while ultrasound combined with CDFI and CDPI, the correspondence increased up to 96.7%. The sonographic features of CDFI and CDPI in choroidal detachment patients were abundant blood flow in band-shape or short stick-like. In 3 cases out of 4 cases with retinal detachment, blood flow was not abundant,their blood flow showed a sparked pattern. In addition, 14 cases combined with vitreous hemorrhage, 8 cases had vitreous opacity and 4 cases vitreous proliferation. Ultrasound diagnosis corresponded with that of clinical surgery in 27 choroidal detachment cases. Conclusions Ultrasound combined with CDFI and CDPI provide valuable references for diagnosis and treatment of choroidal detachment.
