【摘要】 目的:探讨再次玻璃体手术治疗硅油填充眼视网膜脱离的效果。方法:对12例硅油填充眼视网膜脱离患眼行再次玻璃体手术,其中下方视网膜脱离10例,黄斑裂孔复发2例。结果:12例术后视网膜全部复位,10例3~6mo取出硅油。最佳矫正视力提高4行1例,提高3行4例,提高2行3例,提高1行3例,不提高1例。结论:再次玻璃体手术是治疗硅油填充眼视网膜脱离的有效方法,早期手术有重要意义。

Abstract
AIM: To determine the effect of a second vitrectomy in the management of recurrent retinal detachment in silicone oilfilled eyes.
METHODS: Twelve silicone oilfilled eyes of 12 patients with recurrent retinal detachment were performed vitrectomy once again. The retinal detachment of 10 eyes was in the inferior part,and the macular holes relapsed in 2 eyes.
RESULTS: No one of the 12 eyes had a retinal detachment again after the surgery. The silicone oil was uneventfully removed in 10 patients from 3 to 6 monthes. The final bestcorrected visual acuity (BCVA) raised 4 rows in 1 eye, 3 rows in 4 eyes, 2 in 3 eyes and 1 in 3 eyes. Visual acuity of one eye did not raise.
CONCLUSION: There is a favorable effect of vitrectomy on recurrent retinal detachment of the silicone oilfilled eyes, especially in the early time.
KEYWORDS: vitrectomy; silicone oil; retinal detachment; endolaser photocoagulation
0引言
硅油填充眼视网膜脱离是严重的术后并发症和后遗症,积极行再次玻璃体手术对于最终保留患者残余视功能具有重要意义。现将我院收治的一组再次玻璃体手术治疗硅油填充眼视网膜脱离的临床资料分析报告如下。
1对象和方法
1.1对象 200607/200807我院收治的硅油填充眼视网膜脱离12例12眼,其中男7例7眼,女5例5眼,年龄37~76(平均58)岁。硅油填充术后至发现视网膜再脱离的时间为7~60(平均21.3)d。其中特发性黄斑裂孔复发2例,下方局限性视网膜脱离5例,下方广泛视网膜脱离5例。
1.2方法 特发性黄斑裂孔2例皆为白孔,伴有重度后巩膜葡萄肿。1例硅油填充后1wk即发生后极部视网膜浅脱离。持续俯卧位2wk联合药物治疗无效后予再次手术治疗。术中保留原有硅油,硅油下用剥膜钩在黄斑裂孔周围视网膜表面轻轻搔刮,剥离视网膜前膜,加注少量硅油升高眼压,笛针由原黄斑裂孔吸净视网膜下液。等待数分钟后再次吸视网膜下液,重复数次,直至无视网膜下液再产生。调整眼压适中后关闭切口。另1例术后2wk后极部视网膜浅脱离,俯卧位及药物治疗2wk无效后予再次手术。取出硅油后剥离首次手术未处理的视网膜内界膜,气液交换后再次硅油填充。下方局限性及广泛视网膜脱离10例中3例先行环扎,再行玻璃体手术。所有10例患眼均取出原填充硅油,剥离视网膜前膜和下膜,特别是剥离和切除前段增生性玻璃体视网膜病变(proliferative vitreoretinopathy,PVR)。在下方视网膜脱离较低处造孔,气液交换彻底排除视网膜下液,Ⅱ级光斑充分光凝封闭所造视网膜孔及所发现的全部裂孔,并在下方形成较宽广的光凝封闭带。4例在重水下光凝,气液交换后其中2例仍有视网膜下液,经造孔后排出。4例存在锯齿缘周围裂孔,无法行激光光凝封闭,在显微镜直视下经巩膜冷凝予以封闭。所有10例患眼均再次行硅油填充,填充时排净气体,填充量充分,填充结束后调整眼压适中。
