We present a case of traumatic commotio retinae (CR), in which blood flow was evaluated using optical coherence tomography angiography (OCTA).
An 18-year-old Japanese man presented with traumatic retinal detachment and CR in his left eye, which had been hit by a handball. Fundus examination revealed peripheral retinal tear extending from the 1 to 3 o'clock position with retinal detachment, and CR near the area of tear. Fluorescein angiography (FA) confirmed an ischemic area near the retinal tear area at the CR. The patient underwent successful scleral buckling and cryopexy. Sequential OCTA imaging was performed and we were able to determine perfusion in the CR area, with maintained blood flow.
In blunt eye trauma, peripheral commotio retinae can be assessed non-invasively over time using OCTA. OCTA is a useful method for evaluating peripheral retinal whitened areas.
我们报告一例创伤性视网膜震荡（CR）病例，其中使用光学相干断层扫描血管造影（OCTA）评估了血流情况。
一名18岁的日本男性因左眼被手球击中，出现创伤性视网膜脱离和CR。眼底检查发现周边视网膜裂孔从1点至3点位置延伸并伴有视网膜脱离，裂孔区域附近存在CR。荧光素血管造影（FA）证实CR处视网膜裂孔区域附近存在缺血区。患者成功接受了巩膜扣带术和冷冻疗法。进行了连续的OCTA成像，我们能够确定CR区域的灌注情况，血流得以维持。
在钝性眼外伤中，可使用OCTA随时间对周边视网膜震荡进行无创评估。OCTA是评估周边视网膜白色区域的有用方法。
