A 48-year-old woman with a history of retinal detachment repair with vitrectomy, scleral buckling, and silicone oil with subsequent oil removal was referred for unilateral upper eyelid ptosis with edema and overlying skin changes simulating xanthelasma. During surgical excision, a white flare-like plume was noted when the carbon dioxide (CO2) laser was used to make the incisions. The pathology report confirmed silicone oil intrusion in the conjunctiva and upper eyelid. A postoperative in vitro experiment showed that silicone oil was readily ignited by the CO2 laser.
一位 48 岁女性，既往有视网膜脱离修复术病史，行玻璃体切除术、巩膜扣带术和硅油填充，随后行硅油取出术。患者因单侧上眼睑下垂伴水肿和上覆皮肤改变就诊，外观类似于黄色瘤。行手术切除时，使用二氧化碳（CO2）激光进行切口时，可见到白色似羽毛状的闪光。病理报告证实硅油侵入结膜和上眼睑。术后体外实验表明，CO2 激光可轻易点燃硅油。
