作者报告了四例视网膜光凝的病人,在盐酸利多卡因球后麻醉后发生了视网膜中央动脉栓塞。其中一例先后出现两次栓塞。仅一例造成永久性视力丧失,均无球后出血。为顺利进行视网膜光凝经常应用球后麻醉,尽管球后麻醉通常有效而安全,但严重的合并症偶有发生:眼球穿孔,闭塞物质注射到血管内,如果直接伤及视神经可以引起严重的视力丧失,暂时的颅神经麻痹也有报导,球后注射后因球后出血致视网膜中央动
The authors report four patients with retinal photocoagulation who developed a central retinal artery embolization following lidocaine hydrochloride. In one case, there were two embolisms successively. Only one case of permanent loss of vision, no bleeding after the ball. Retinal photocoagulation is often followed by post-retrobulbar anesthesia. Although post-retroversial anesthesia is generally effective and safe, severe comorbidities occasionally occur: perforation of the eye, occlusion of the substance into the bloodstream, and serious visual acuity if the optic nerve is directly injured Loss, temporary cranial nerve palsy has also been reported after posterior retrobulbar injection due to the central retinal hemorrhage
