The authors describe an original technique for treating multiple subretinal perfluorocarbon liquid (PFCL) bubbles complicating previous surgery for rhegmatogenous retinal detachment.
To facilitate the induction of macular redetachment and peripheral displacement of the PFCL bubbles, we performed the subretinal injection of filtered air in addition to balanced salt solution. In this setting, the action of the PFCL in the vitreous cavity, combined with globe manipulation, allowed bubbles' displacement and full aspiration.
A 57-year-old man had a history of repeated pars plana vitrectomies for recalcitrant rhegmatogenous retinal detachment, the latter leading to multiple subretinal PFCL bubbles retained at the posterior pole. The described technique was performed 8 weeks after the last pars plana vitrectomy. A complete flattening of the macular region was obtained with visual improvement.
Direct injection of air into the subretinal space may represent an effective strategy to help the surgical management of multiple retained PFCL bubbles.
作者描述了一种治疗复杂性视网膜脱离手术后多发性视网膜下全氟碳液体（PFCL）气泡的原创技术。
为了促进黄斑再脱离和 PFCL 气泡向周边的移位，我们除了平衡盐溶液外，还进行了视网膜下过滤空气注射。在这种情况下，PFCL 在玻璃体腔中的作用，结合眼球操作，允许气泡的移位和完全抽吸。
一名 57 岁男性曾因顽固性孔源性视网膜脱离多次接受经睫状体平坦部玻璃体切除术，后者导致后极部多发性视网膜下 PFCL 气泡残留。描述的技术是在最后一次经睫状体平坦部玻璃体切除术后 8 周进行的。黄斑区域完全变平，视力改善。
直接向视网膜下空间注入空气可能是帮助处理多发性残留 PFCL 气泡的有效策略。
