彩色多普勒超声检查在外伤性视网膜脱离中的应用

Application of Color Doppler ultrasound in diagnosis of traumatic retinal detachment

目的探讨彩色多普勒超声对外伤性视网膜脱离的诊断价值。方法收集经眼B型超声和手术证实的外伤性视网膜脱离患者30例（30只眼），运用彩色多普勒超声观察眼外伤后玻璃体内声像图特征及血流情况。结果部分性脱离18例，完全性脱离9例，陈旧性脱离2例，合并脉络膜脱离的视网膜脱离1例；30例中，视力大于0．1者7只跟（23．3％）、0．01～0．1者10只眼（33．3％）、数指4只眼（13．3％）、手动5只眼（16．6％）、无光感4只眼（13．3％）；视力治疗后较治疗前有明显的提高（X^2=7．394，P=0．015）；手术后12眼（40．0％）为低眼压，视网膜下出血4眼（33．3％），浆液性脉络膜脱离4眼（33．3％），出血性脉络膜脱离4眼（33．3％）；三组患眼的低眼压发生率差异无统计学意义（X^2=3．004，P=0．243）。结论彩色多普勒超声检查外伤性视网膜脱离准确、可靠，对临床治疗及预后判断具有重要的意义。

Objective To research the diagnosis value in color Doppler ultrasound on traumatic retinal detachment. Methods 30 cases（30 eyes）with traumatic retinal detachment were confirmed by B-mode uhrasonography and surgery. The characteristics and blood flow were observed by color Doppler ultrasound. Results 30 eases, among partial detachment in 18 cases,completely detachment in 9 cases,old detachment in 2 eases, and completed with detachment of choroids in 1 ease;30 cases, greater than 0.1 in 7 eyes （ 23.3% ）, 0. 01 -0. 1 in 10 eyes （33, 3% ）, counting fingers in 4 eyes（ 13.3% ） ,manual in 5 eyes （ 16.6% ） ,no light perception in 4 eyes（ 13.3% ） ; The visual acuity in patients after treatment had significantly increased compared with before treatment （ X^2 = 7. 394,P = 0. 015 ） ; The lower intraocular pressure of retinal hemorrhage, serous choroidaland hemorrhagic choroidal had no significant difference[4 eye（33.3% ） ,4 eye（33.3% ） ,4 eye（33.3% ） ,respectively] （X^2 =3.004 ,P =0. 343）. Conclusion The color doppler ultrasound diagnosis in traumatic retinal detachment, with its capacity of early finding and accurate and reliable, have significant meaning to clinical treatment and prognosis.
