机械性眼外伤后无光感眼的手术治疗分析

目的 回顾性总结严重机械性眼外伤后视力无光感眼的伤情、相应的手术治疗方式及其手术治疗后效果,分析对手术后视力结果和眼球最终结局的影响因素.方法 对42例42只眼严重眼外伤所致的无光感眼施行玻璃体视网膜联合手术,观察其疗效.术后随访6～36个月,平均15个月.结果 42例外伤后无光感眼中,15例术后恢复了光感或光感以上的视力,27例仍无光感,其中2例行眼球摘除.严重眼外伤无光感眼视功能丧失主要原因为致密浓厚玻璃体积血、视网膜脱离及视网膜、脉络膜严重广泛的损伤、缺损.而术前伤情、玻璃体手术时机等均会影响手术的成功和视力预后.结论 严重眼外伤后无光感并不意味着视力永久性的丧失,正确的早期修复和适时、恰当的玻璃体视网膜手术,可获得一定的视力,视力无法恢复者可暂时维持眼球外观.     

严重眼外伤中玻璃体手术的应用

目的 观察玻璃体手术治疗严重眼外伤的效果。方法 严重眼外伤采用闭合式玻璃体切除，联合视网膜脱离复位术、眼内异物摘出、视网膜切开、注入过氟化碳液体、眼内光凝、眼内注药、C3F8气体或硅油填充。结果 严重眼外伤178例182眼中116眼视力提高，占63．74％；57眼视力不变，占31．32％；9眼下降，占4．95％。术前无光感的19眼中，7眼恢复光感以上视力。摘出36眼玻璃体内或视网膜前异物及20眼后段眼球壁异物。有4眼视网膜下异物未施行摘取。6l眼视网膜脱离，其中55眼视网膜复位，视网膜解剖复位率90．16％。结论 经过适时恰当的玻璃体手术，大多数严重眼外伤都能挽救眼球并恢复有用的视力。     

玻璃体视网膜手术治疗严重眼外伤无光感眼的效果

目的评价玻璃体视网膜手术治疗严重眼外伤所致的无光感眼的效果。方法对13例13只眼严重眼外伤所致的无光感眼进行玻璃体视网膜手术,观察其疗效。随访时间为3m～18m,平均为12m。结果13只严重眼外伤后无光感的眼中,有9例术后有了光感或光感以上的视力,最终4例仍无光感。结论眼外伤后无光感的主要原因是严重的玻璃体混浊积血、屈光间质混浊、视网膜脱离及视网膜、色素膜的损伤、缺损。眼外伤后无光感在一些病例中并不意味着视力永久性的丧失,及时进行玻璃体视网膜手术,使尚存的视网膜复位,可使这些伤眼再获得光感以上的视力。

Abstract：

Objective To evaluate the efficacy of vitreoretinal surgery in the treatment of traumatized eyes with no light perception. Methods Vitreoretinal surgery on 42 eyes of traumatized eyes with no light perception of 42 patients was performed. The patients after the operations were followed up for 6-36 months (averaged 15 months). Results Postoperatively; 15 of 42 patients had visual acuities of LP to 0.1, 27 eyes remained NLP in which 2 had enucleation. The traumatic condition; the opportunity of vitreoretinal surgery were the most important factors influencing the prognosis of postoperative VA in severe mechanical injuried eye.Conclusions The dense vitreous hemorrhage, the damaged or detached retina and the choroid edema are the main causes of NLP. Therefore; NLP does not always mean permanent loss of vision. Some patients of NLP may get some visual acuities after proper primary repair of the wound and timely vitreoretinal surgery. The eyes with NLP can maintain eyeball- shape.     

玻璃体切割联合手术治疗严重眼外伤的临床观察

目的：探讨玻璃体切割联合手术治疗严重眼外伤的临床疗效。方法：回顾性分析我院自2011-01以来收治的经玻璃体切割联合手术治疗的严重眼外伤患者30例31眼。结果：患者31眼中术后视力提高24眼,术前无光感12眼中术后视力不变2眼,光感2眼,手动3眼,指数4眼,1眼恢复为0.1;6眼球内异物的异物取出率为100%,炎症控制好;18眼复杂视网膜脱离,15眼成功复位,视网膜复位率为83%;14眼外伤性白内障或晶状体脱位,玻璃体手术后12眼行人工晶状体植入术,晶状体植入率为86%。结论：严重眼外伤包括术前无光感眼,经过恰当的玻璃体手术联合相应的治疗措施,可以最大限度保留患者的眼球及挽救患者的视功能。     

伴致密玻璃体出血的外伤后无光感眼的玻璃体手术探查

目的评估对一些外伤后无光感眼施行玻璃体手术探查的效果。方法对１０例外伤后无光感眼行玻璃体手术探查和处理，其中８例为开放性眼外伤，２例为闭合性钝挫伤。结果术后６例恢复了光感至０．２５的视力，４例仍为无光感。术中发现一些眼仍保留有功能的后极部视网膜和视盘。结论致密玻璃体积血可能是一些严重外伤眼术前无光感的主要原因。因此，无光感并不总是意味着永久性视力丧失。正确的初期修复和适时地对经选择的眼施行二期玻璃体手术探查，可能为有些伤眼提供复明机会。     

Scleral buckling surgery for stage 4B retinopathy of prematurity.

Results of scleral buckling in 15 consecutive eyes of 13 infants with stage 4B retinopathy of prematurity (ROP) were reviewed. Ten of 15 retinas achieved macular reattachment with a single scleral buckling procedure. Four of 15 retinas unable to be attached by scleral buckling were reattached after the addition of a single vitreous operation. One of 15 retinas was unable to be reattached despite both a scleral buckling and a single vitreous procedure. Despite macular attachment in all except one eye, visual results were disappointing. Fix and follow visual acuity was present in 3 eyes, light perception in 11 eyes, and no light perception in 1 eye. Average follow-up was 10 months. Possible causes for poor visual outcomes despite retinal reattachment include retinal abnormalities as a result of detachment and amblyopia.     

眼外伤玻璃体切除术前ERG及VEP检查对术后视力预测价值

目的 观察闪光视网膜电图（flicker electroretinogram,F-ERG）及闪光视诱发电位（flicker visual evoked potential,F-VEP）测定对眼后段外伤玻璃体切除术后视力预测价值。方法 对42例（42只眼）眼后段外伤伴玻璃体混浊或积血的患者在玻璃体切除术前两周内行F-VEP及F-ERG检查,并分析其与术后1个月最佳矫正视力的关系。结果 F-ERG检查正常或轻度异常25只眼,术后视力提高23只眼（92．0％）,中度异常或重度异常和记录不到波形17只眼,术后视力提高7只眼（41．2％）。F-VEP检查正常或轻度异常27只眼,术后视力提高24只眼（88．9％）,中度异常或重度异常和记录不到波形15只眼,术后视力提高5只眼（33．3％）。F-VEP及F-ERG均正常或轻度异常的18只眼,术后视力均提高,且术后视力均恢复至0．1以上。F-VEP及F-ERG均重度异常或记录不到波形的2只眼,术后视力1只眼下降,1只眼不变。结论 眼外伤玻璃体切除术前联合检测F-VEP及F-ERG对术后视力预测有重要意义。     

玻璃体切除术治疗严重眼挫伤所致玻璃体积血

目的观察玻璃体切除术治疗严重眼挫伤所致大量玻璃体积血的效果。方法回顾性分析76例（76只眼）严重眼外伤所致大量玻璃体积血玻璃体切除术的术前及术后情况。结果76只眼中术后视力提高者73只眼。术前无光感的4眼中术后仍无光感1只眼,光感2只眼,1只眼视力恢复至0．6。22只眼视网膜脱离者中,21只眼成功复位,复位率为95．45％。外伤性晶状体脱位28只眼,玻璃体术后一期人工晶状体植入5例。外伤性黄斑孔4只眼,3只眼玻璃体切除术中联合内界膜剥离,术后黄斑孔闭合。1例因黄斑区视网膜下大量积血,内界膜未剥离,孔未闭合,进行激光光凝,以防止孔周围视网膜脱离。结论严重眼挫伤所致大量玻璃体积血,均可在外伤后及时进行玻璃体切除术治疗,对于术前无光感眼,当眼B超显示玻璃体团块状回声,未能分清视网膜及脉络膜结构者,需待玻璃体机化后,经过恰当的玻璃体切除术联合其他相应的治疗措施,大多能解剖治愈,部分患者可功能治愈。     

内窥镜引导玻璃体视网膜手术治疗伴有角膜混浊的外伤性视网膜脱离

目的探讨眼内窥镜引导玻璃体视网膜手术治疗伴有角膜混浊的外伤性视网膜脱离的效果及安全性。方法 2010年8月至2011年6月我院13例(13眼)伴有角膜混浊的外伤性视网膜脱离患者,在眼内窥镜引导下行玻璃体切割、视网膜激光光凝术及玻璃体硅油或重硅油填充术,术后随访6～15个月,观察视力、眼压、眼前段及眼底视网膜复位情况。患者术前视力:无光感者2眼,光感者5眼,手动者3眼,数指者2眼,0.02～0.05者1眼。结果所有患者视网膜均平伏,裂孔均封闭。术中1眼玻璃体内发现术前未能诊断的非磁性异物(睫毛)。术后4眼早期眼压偏低,2眼一过性眼压增高,经观察或药物治疗后恢复正常。术后6个月最佳矫正视力:无光感者2眼,光感者2眼,手动者2眼,数指者5眼,0.02～0.20者2眼。结论眼内窥镜扩展了玻璃体切割术的适应范围,提高了对伴有角膜混浊的外伤性视网膜脱离,尤其是伴有周边部视网膜裂孔者,实施玻璃体视网膜手术的准确性和安全性。     

Perfluoro-N-octane (PFO) in the repair of complicated retinal detachments due to severe proliferative diabetic retinopathy

PURPOSE: To report our experience with perfluoro-N-octane (PFO) in the surgical management of complicated retinal detachments due to proliferative diabetic retinopathy. METHODS: Retrospective review of 18 consecutive eyes of 18 patients with tractional or combined tractional and rhegmatogenous retinal detachments due to severe proliferative diabetic retinopathy managed by pars plana vitrectomy and the intraoperative use of PFO. Preoperative characteristics, intraoperative findings and procedures and postoperative results were recorded. RESULTS: The mean preoperative acuity was 2/200 (range, 20/25 to light perception). The mean final visual acuity was 4/200 (range, 20/20 to no light perception). With a mean follow-up of 6 months, there was an 89% anatomic reattachment rate at the last visit and visual acuity was stable or improved in 72% of eyes. CONCLUSIONS: In our experience, PFO is a helpful surgical adjunct in the anatomic reattachment of tractional or combined tractional and rhegmatogenous diabetic retinal detachments. Visual acuity was stabilized or improved in the majority of eyes.     

Severe proliferative vitreoretinopathy and retinal detachment. II. Surgical results with scleral buckling

Prior to the era of vitrectomy, scleral buckling was used to treat 521 eyes with total retinal detachment and proliferative vitreoretinopathy (PVR) of various degrees of severity. The retina was reattached for at least six months in 46.9% of eyes; the anatomic success rate decreased with increasing severity of PVR. Within each grade of PVR, the reattachment rate was higher for eyes with smaller breaks than for eyes with larger breaks, and the prognosis was not worse when smaller breaks were found than when no breaks were found. The cumulative success rate rose with increasing number of reoperations. None of the anatomically successful cases had a final visual acuity of no light perception; 82.9% of them achieved a visual acuity of counting fingers or better. The prognosis for visual improvement after successful scleral buckling was unrelated to the preoperative severity of PVR. Severe intraoperative complications occurred in 5.0% of the eyes, all of which resulted in failure.     

Long-term anatomical and visual outcome of vitreous surgery for retinal detachment with choroidal coloboma

CONTEXT: Vitreous surgery has been advocated as an alternative treatment of selected retinal detachments with choroidal colobomas. AIM: To study the long term anatomical and visual outcome of choroidal coloboma with retinal detachment managed by pars plana vitrectomy with silicone oil tamponade. SETTING AND DESIGN: Retrospective study conducted in a tertiary eye care hospital. MATERIALS AND METHODS: Fourty two eyes of 40 patients with retinal detachments related to coloboma of the choroid without any peripheral breaks were analyzed. All eyes underwent pars plana vitrectomy with internal tamponade using silicone oil. Endolaser was performed along the coloboma border. Silicone oil was removed in 50% of patients. The main outcome measures were retinal reattachment and visual recovery. SPSS (Statistical Package for the Social Science), version 10.0 was used for analysis. RESULTS: The retina in all cases (100%) undergoing vitrectomy were completely reattached intra-operatively. After a mean follow-up of 14 months, 37 (88.1%) eyes had attached retina. The best corrected visual acuity was 10/200 or better in 33 (78.4%) eyes. The best corrected visual acuity improved from a preoperative median of counting fingers (range 20/40 to perception of light) to median best corrected visual acuity of 20/200 (range 20/40 to perception of light) at the end of 6 months. Of the 50% (21) cases that underwent silicone oil removal, two eyes had re-detachment of retina. CONCLUSION: Pars plana vitrectomy along with silicone oil tamponade for retinal detachment related to choroidal coloboma improves the long-term anatomical and visual outcome.
