硅油填充眼复发性视网膜脱离的手术治疗

目的:探讨硅油填充眼复发性视网膜脱离的原因、手术方法选择及临床疗效。方法:对29例29眼硅油填充眼复发性视网膜脱离的原因、手术方式、解剖复位和视功能恢复结果进行分析。结果:复发性视网膜脱离由增生性玻璃体视网膜病变(proliferative vitreoretinopathy,PVR)引起者15眼行硅油取出+剥膜+注气或硅油填充术;裂孔未封闭者行剥膜+硅油填充+光凝,其中周边裂孔8眼,黄斑裂孔2眼,巨大裂孔后瓣漏脱者2眼,7眼联合巩膜扣带(外加压);2眼行环扎巩膜扣带+外加压+外放液+冷凝;术后均获得解剖复位,视功能提高者15眼,随访4mo,6眼复发。结论:硅油填充眼视网膜脱离的原因是多种的,根据不同的眼底表现应该选择不同的手术方法。     

硅油取出后远期复发性视网膜脱离的回顾性研究

目的分析硅油取出后远期随访（≥1年）,发生复发性视网膜脱离的原因和再次手术的方法。方法检索我院1993年-2005年住院病史数据库,行硅油取出术2771例（2771眼）。其中9例9眼在1年后发生视网膜再脱离,进行回顾性分析。结果9眼在硅油取出后24.11月±16.22月发生视网膜再脱离,其中5眼有明确视网膜裂孔,8眼有视网膜前膜的再增殖。9眼再次行视网膜复位术,8眼再次硅油填充,1眼C3F8填充。术后随访55.67m±31.80m,9眼视网膜完全复位。结论硅油取出后1年发生的远期视网膜脱离,主要原因为视网膜前膜的再增殖,尤其位于下方眼底和玻璃体基底部。高度近视合并黄斑裂孔可能是另一个主要因素。再次手术的解剖成功率仍令人满意,大部分眼需再次行硅油填充。     

复发性视网膜脱离玻璃体视网膜手术

本文对１９９４年１２月—１９９５年９月间行玻璃体切除术，膜剥离、视网膜切开、松解视网膜的５４眼病例进行回顾性分析。结果，出院时视网膜复位５０眼（９２．５％）、失败４眼（７．５％）。因此，只要医生能熟练掌握好常规视网膜脱离手术和玻璃体、视网膜显微手术的技巧及手术适应症，临床上难以治愈的复发性增殖性玻璃体视网膜病变Ｄ级的视网膜脱离病例，就能取得良好的效果。     

视网膜脱离行玻璃体切割术后硅油眼复发视网膜脱离的诊疗现状

视网膜脱离患者玻璃体切割(PPV)术后硅油填充状态下复发视网膜脱离是较为特殊的一类复发性视网膜脱离,大部分需要二次手术,为临床工作带来挑战,硅油眼视网膜脱离的诊断和治疗与其他视网膜脱离存在一些差异,术前医患充分沟通以及合理选择诊疗方案,术中注意高危因素,对该病预后至关重要。     

硅油术后复发性视网膜脱离的临床观察

玻璃体切除联合硅油填充的方法大大提高了复杂视网膜脱离的解剖复位率，然而远期疗效不尽相同，仍有１１％～５３％视网膜脱离复发的可能，１９９５年２月～１９９５年１２月连续收治１５例硅油术后复发性视网膜脱离，分别采取巩膜外手术，硅油下视网膜手术，硅油取出后玻璃体一视网膜手术等方法进行治疗。术后１２例视网膜复位（８０％），其术后视力为０．１～０．７者１０只眼，０．０５以下者２只眼，随访３～１０个月，平均４．     

二次硅油注入术治疗复发性视网膜脱离

目的：分析带硅油复发性视网膜脱离的原因,总结二次硅油注入术治疗硅油眼复发、复杂性视网膜脱离的效果。方法：对150例带硅油眼的复发性视网膜脱离,其中40例复杂性视网膜脱离接受二次硅油注入术进行了回顾性分析。结果：带硅油眼的视网膜脱离以下方为主,其主要原因为硅油上浮,原裂孔封闭不好或裂开,新裂孔形成,增殖性玻璃体视网膜病变（PVR）的牵引。对40例带硅油眼的视网膜脱离进行了硅油再次注入术,平均随访8个月。视网膜解剖复位34例（85％）。二次硅油取出术12例,视网膜解剖复位9例（75％）。结论：带硅油眼的复发性视网膜脱离的主要原因是玻璃体牵引,对于复杂性病变,行硅油再次注入术成功率较高。

Outcomes of Recurrent Retinal Detachment Surgery following Pars Plana Vitrectomy for Rhegmatogenous Retinal Detachment

Aim: To study the anatomical and functional outcomes of recurrent retinal detachment (RD) surgery following pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment. Methods: Retrospective analysis of 133 consecutive cases of recurrent RD. Inclusion criteria: age ≥18 years, recurrent RD following PPV ± encircling band for rhegmatogenous RD. Exclusion criteria: age <18 years, post-endophthalmitis/tractional/exudative/combined RD, post-scleral buckle, primary surgery done at another institute. The final anatomical and functional outcomes, and their association with clinico-surgical factors, were analyzed. Results: Proliferative vitreoretinopathy (PVR) ≥ Grade C in re-detached retina (OR, 2.49; 95% CI, 1.02–6.09; P = 0.045) and need for multiple resurgeries (OR, 6.48; 95% CI, 2.51–16.69; P < 0.0001) were significant risk factors for the final anatomical failure. Eyes with PVR ≥ Grade C (OR, 0.31, 95% CI, 0.12–0.80; P = 0.013) in primary RD, and with multiple breaks (OR, 0.24; 95% CI, 0.06–0.96; P = 0.044) at the time of recurrent RD, were less likely to have final BCVA ≥20/200. The visual acuity at the time of recurrent RD had a moderately positive correlation (r = 0.454, P < 0.001), and the delay in recurrence of RD had a weakly positive correlation (r = 0.214, P = 0.046) with the final BCVA. Conclusions: PVR ≥ Grade C and multiple resurgeries are associated with higher incidence of anatomical failure in recurrent RD surgery. Multiple breaks are associated with a poorer visual outcome, whereas a better baseline visual acuity and delayed recurrence of RD after primary repair are associated with a better visual outcome.     

Retinal Layers Measurements following Silicone Oil Tamponade for Retinal Detachment Surgery

This study aimed to investigate the influence of silicone oil on the retinal nerve fiber layer (RNFL) thickness in patients with primary rhegmatogenous retinal detachment who underwent vitreoretinal surgery. The study included 47 patients (eyes), who underwent a pars plana vitrectomy with the silicone oil tamponade. The control group included unoperated eye of all participants. Spectral-domain optical coherence tomography (SD-OCT) was used for the measurements of peripapilar and macular RNFL thickness. The average peripapillary RNFL thickness was significantly higher in the silicone oil filled eyes during endotamponade and after its removal. The eyes with elevated IOP had less thickening of the RNFL in comparison to the eyes with normal IOP. Central macular thickness and macular volume were decreased in the silicone oil filled eyes in comparison to the control eyes. In conclusion, silicone oil caused peripapilar RNFL thickening in the vitrectomized eyes during endotamponade and after silicone oil removal.     

Complications of Emulsified Silicone Oil after Retinal Detachment Repair

Abstract

Intraocular silicone oil has several important indications in vitreoretinal surgery, particularly the repair of complicated retinal detachments. Emulsification is a clinically significant complication of using silicone oil tamponade. There are several factors that can promote or prevent silicone oil emulsification after retinal detachment repair, including protein surfactants, contaminants, and shear forces. However, the duration of tamponade remains the most significant one. After emulsification has occurred, keratopathy and glaucoma are the most common complications. However, recent work has shown that emulsification can also affect the retina, optic nerve, and even extraocular structures. Limiting the amount of time the silicone oil remains in the eye is the most important factor in reducing its complications.     

硅油填充术在不伴有视网膜脱离外伤性感染性眼内炎的临床应用

目的：观察玻璃体切除联合眼内注药或硅油填充术对眼球穿通伤后合并感染性眼内炎不伴视网膜脱离的疗效。 方法：应用经睫状体平坦部玻璃体切除术，以联合眼内注药或硅油填充术分组治疗30只眼球穿通伤并发感染性眼内炎不伴有视网膜脱离患者，术后予以静脉、结膜下及眼药水途径给予抗感染抗炎治疗。 结果：玻璃体切除术后追踪随访3～12个月，2组30只眼细菌性感染全部控制，术后视力较术前视力有显著性提高，联合眼内注药组19只眼，其中4只眼（21．1％）发生视网膜脱离：联合硅油填充组11只眼，其中术后1只眼（9％）发生视网膜脱离。两组术后并发症发生率均无明显差异（P〉0．05）。 结论：玻璃体切除联合硅油填充术能有效控制炎症，稳定视网膜功能，对一些视网膜情况不佳或炎症难以控制的患者可以考虑术中应用硅油。     

Study on Application of the Silicone Oil in the Reattachment of Complicated Retinal Detachment

Sixty eyes with complicated retinal detachment were treatedby vitrectomy combined with silicone oil tamponade (27 eyes of PMR gradeD,15 eyes of giant retinal tears with posterior flat folded-over,13 eyes ofposterior or macular hole,5 eyes of traumatic PVR).After 3-24 monthsfollow-up,the study showed retinal anatomic reattachment in 48 eyes inwhich the visual acuity of 32 eyes was 0.05 or better.The authorsconsider that vitrectomy and peeling make the silicone oil tamponadeperfect the vitreous surgery and improve the successful rate.The theoryof silicone oil tamponade,the indications,advantages and disadvantagesof silicone oil tamponade are discussed in this paper.Eye Science1993,9:146-148.     

Outcome of Complex Retinal Detachment Surgery after Silicone Oil Removal

BACKGROUND AND OBJECTIVE: To evaluate anatomical prognosis after silicone oil removal. PATIENT AND METHODS: Sixty-eight eyes which underwent silicone oil removal were enrolled into the study. The underlying ocular pathology for pars plana vitrectomy, surgical methods, and time of silicone oil removal were analysed. RESULTS: Sixteen of 68 eyes (23.5%) redetached following the removal of silicone oil. According to etiology redetachment rates: PVR C 9.5% (2/21), PVR D 25% (4/16), trauma without intraocular foreign body 27.3% (3/11), with intraocular foreign body 33.3% (2/6), giant retinal tear 37.5% (3/8), and proliferative diabetic retinopathy with tractional retinal detachment 33.3% (2/6). The rate of redetachment was 22% in patients with encircling band and 27.8% without encircling band. Retina was redetached in the first 10 days in 81.3% of patients after silicone oil removal. CONCLUSION: The residual vitreoretinal traction especially at the vitreous base is the most likely reason for retinal redetachment after silicone oil removal, which is most commonly seen during the first 10 days.     

Vitrectomy with Silicone Oil Tamponade in Rhegmatogenous Retinal Detachment following Acute Retinal Necrosis: Clinical Outcomes and Prognostic Factors

Purpose: The purpose of the study is to report the prognostic factors and outcomes of vitrectomy (PPV) with silicone oil tamponade in rhegmatogenous retinal detachment (RRD) secondary to acute retinal necrosis (ARN).

Methods: This retrospective, non-randomized, interventional comparative study included 38 eyes of 38 patients. All cases underwent PPV with silicone oil tamponade. The main outcome measure was improvement of final visual acuity relative to the presenting visual acuity and factors affecting the same Group A included eyes with favorable vision of 20/400 or better and Group B included the others.

Results: Group A included 16 eyes (42.10%), group B included 22 eyes (57.89%). In Group A 2 eyes out of 16 (12.5%) and in Group B 12 eyes out of 22 (54.54%) had RRD at presentation (p = 0.02, 95% CI for the difference 7.88–65.78%). The time interval between first presentation and development of RRD in Group A was 30.94 ± 38.8 days (median 30 days) whereas that in Group B was 10.81 ± 11.73 days (median 8 days) (p = 0.02). The odds of visual improvement post-vitrectomy when RRD occurred later was 8.4 (p = 0.01, 95% CI 1.53–46.1). The usage of systemic steroids (odds 5.2, p = 0.03, 95% CI 1.14–23.54) and oral valacyclovir (odds 4.33, p = 0.04, 95% CI 1.05–17.84) were associated with odds favoring a good visual outcome. Recurrent RRD was noted in 3/16 eyes (18.75%) in Group A and 13/22 eyes (59.09%) in Group B (p = 0.03).

Conclusion: Delayed occurrence of RRD after ARN is a good prognostic factor. Usage of systemic steroids and oral valacylocvir are associated with a favorable visual outcome when started before the onset of RRD.
