Abstract

Background: Visual and anatomical success of inferior retinectomy in proliferative vitreoretinopathy complicating recurrent retinal detachment (RD). Aims: The aim of this study was to evaluate anatomical and visual outcomes of retinectomy in eyes with recurrent RD with advanced proliferative vitreoretinopathy. Settings and Design: Institutional, observational, cross-sectional retrospective study. Subjects and Methods: Records of 56 eyes of 56 patients with recurrent RD and proliferative vitreoretinopathy (PVR) were evaluated, three-port incision sclerotomies followed by standard vitrectomy were done. Retinal reattachment was achieved with the aid of perfluorocarbon and retinectomy. Retinectomy was performed at the time of surgery based on retinal shortening (inferior 180°). Silicon oil (SO) was used as a tamponade. Retinal attachment and visual acuity (VA) after 6 months were evaluated. Statistical Analysis Used: Chi-squared test. Results: In all 52 of 56 (93%) eyes, retinal reattachment was successful, with a mean follow-up of 25 months (range, 6–70 months). After retinal reattachment, VA improved or stabilized in 39 of 56 patients (70%). Conclusion: When combined with anterior base dissection, inferior retinectomy may be useful in the surgical treatment of complex PVR-related RD. It was found that with lensectomy, radical anterior base dissection, and inferior retinectomy, anatomic success rates are improved and visual function can be maintained.
晚期增殖性玻璃体视网膜病变视网膜切除术的解剖和视觉效果
背景:下视网膜切除术治疗增殖性玻璃体视网膜病变合并复发性视网膜脱离(RD)的视觉和解剖学成功。目的:本研究的目的是评估视网膜切除术治疗复发性RD合并晚期增殖性玻璃体视网膜病变的解剖和视力结果。背景和设计:机构性、观察性、横断面回顾性研究。对象和方法:对56例复发性RD合并增殖性玻璃体视网膜病变(PVR)患者56只眼的记录进行评价,并行三孔切口巩膜切除术后标准玻璃体切除术。在全氟碳化物和视网膜切除术的帮助下,视网膜重新附着。在视网膜缩短(下180°)的基础上,手术时进行视网膜切除术。硅油(SO)作为填塞剂。观察6个月后视网膜附着及视敏度。统计学方法:卡方检验。结果:56只眼中52只(93%)视网膜再植成功,平均随访25个月(范围6-70个月)。视网膜再植后,56例患者中有39例(70%)VA改善或稳定。结论:下视网膜切除术联合前基底清扫术可用于复杂pvr相关性RD的手术治疗。我们发现晶状体切除术、根治性前基底清扫术和下视网膜切除术可提高解剖成功率并维持视觉功能。
