Background: We encountered obvious arterial bleeding from the incision site during radial optic neurotomy (RON) in a 55- year-old woman with central retinal vein occlusion (CRVO) and report the findings herein. Case report: The patient initially demonstrated a retinal hemorrhage and macular edema due to a left CRVO. Her corrected visual acuity was 0.5 OS. Since her symptoms did not improve and were aggravated, even though she received an oral anticoagulant drug orally, RON was performed 2 months after the onset of symptoms. During surgery, obvious arterial bleeding started from the RON incision site and it was not arrested although the infusion bottle was fully elevated. However, a subsequent infusion of liquid perfluorocarbon successfully stopped the bleeding by direct pressure. Hemorrhagic retinal detachment occurred in the nasal quadrant and postoperative vitreous hemorrhage was treated surgically. The hemorrhagic retinal detachment was gradually absorbed and replaced by fibrous scar tissue. Two years after the surgery, no expansion of retinal detachment has been observed and correctedvisual acuity is being maintained at 0.2 OS. Conclusion: We conclude that RON for CRVO carries a risk of arterial bleeding and that infusion of liquid perfluoro-carbon seems to be effective to arrest arterial bleeding from the RON site.

在二十世纪20年代纪录片形式发明并正式命名之前,非虚构片已经存在二十多年了。如工人离开工厂、火车进站等真实场景的记录。  早期影片包括舞台喜剧、历史事件重演、魔术、滑稽剧及通俗剧;一战时期,大量电影素材记录了战争的所有阶段,电影成为战时各个政府与其人民交流及宣传的重要媒介。这些影片看起来更像是故作爱国主义姿态;这样的新闻片只能算作纪录片的素材,因为他们是凌乱无序的,缺少一部正直纪录片的特质。  这
我走到院子里,踮起脚,拿起挂在墙上的草帽,然后再把一边鸡圈里面的几只公鸡给放出来,撒了几把谷糠给它们吃。我坐在板凳上,呆呆地看着还没亮透的天空,一边的阿姊还在忙着把簸
