目的探讨玻璃体切除联合重硅油眼内填充治疗下方严重PVR视网膜脱离的效果。方法对26例（26眼）诊断为合并下方PVR视网膜脱离者行玻璃体切除联合眼内重硅油填充,并同时随机抽取26眼患相似类型的视网膜脱离者,在玻璃体切除术后给予眼内硅油填充作为对照治疗。术后随访7～12月,观察其视网膜复位、视力、眼压及硅油乳化等情况。结果重硅油组视网膜一次性完全复位者24眼,占92．30％,硅油组一次性视网膜完全复位者18眼,占69．23％,（P〈0．05）。视网膜完全复位者绝大部分视力有不同程度提高。所有患者均未见明显炎症反应。结论玻璃体切除联合重硅油眼内填充是治疗下方PVR视网膜脱离的有效方法,可以降低术后视网膜脱离的复发率。     

Silicone oil tamponade in 23-gauge transconjunctival sutureless vitrectomy

PURPOSE: To describe 20 consecutive patients treated with 23-gauge transconjunctival sutureless vitrectomy and silicone oil tamponade for retinal detachments (RD) of different etiologies. METHODS: Prospective case series. Twenty patients with complex retinal detachment were submitted to a primary 23-gauge transconjunctival pars plana vitrectomy: rhegmatogenous retinal detachment with proliferative vitreoretinopathy (RRD + PVR) in 7 cases, diabetic tractional retinal detachment (DTRD) in 5 cases, giant retinal tear (GRT) in 2 cases, RRD with multiple tears in 2 cases, GRT + uveitis in 1 case, RRD + uveitis in 1 case, DTRD + RRD in 1 case, and RRD + PVR with intraocular foreign body (IOFB) in 1 case. Length of postoperative follow up ranged from 3 to 14 months. RESULTS: Final visual acuity ranged from 20/25 to hand motion. Postoperatively, none of the 20 eyes had hypotony or leakage of silicone oil through the sclerotomies. Seventeen out of 20 (85%) had improved vision. CONCLUSION: Silicone oil tamponade was demonstrated to be a feasible option in conjunction with 23-g transconjunctival sutureless vitrectomy to treat complex retinal detachment.     

Influence of relaxing retinotomy on surgical outcomes in proliferative vitreoretinopathy

PURPOSE: This study sought to determine the influence of relaxing retinotomy (RR) incisions upon surgical outcomes in the repair of recurrent retinal detachment (RD) attributable to proliferative vitreoretinopathy (PVR). DESIGN: Retrospective, consecutive, nonrandomized, single-center series. METHODS: Eighty-one eyes with recurrent RD attributable to PVR were retrospectively reviewed. Exclusion criteria were giant retinal tear, uveitis, trauma, proliferative diabetic retinopathy, and age under 18 years. A total of 52 eyes underwent RR at the time of surgery (64.2%); 29 eyes were repaired without this technique. Perfluorocarbon gas (n = 34) or silicone oil (n = 47) was used as postoperative tamponade. Statistical analyses were performed using the Fisher exact test. RESULTS: Eyes that received RR had significantly higher rates of anterior PVR (P = .009). Eyes receiving silicone oil for postoperative tamponade had worse baseline characteristics compared with those receiving gas. The use of RR in eyes receiving gas tamponade had no marked influence on the initial anatomic outcomes, with recurrent retinal detachment occurring in five of 14 eyes that received an RR and seven of 20 eyes that did not receive an RR (P = .62). Eyes in which silicone oil was used as a postoperative tamponade had a significantly lower rate of recurrent RD requiring additional surgery when RR was employed (one of 38 eyes) when compared with eyes that did not receive an RR (three of nine eyes, P = .02). Ultimately, surgical reattachment was attained in all eyes except one. Eyes that received gas tamponade without RR had significantly better median vision (P = .008). CONCLUSIONS: Surgical management of PVR often results in ultimate retinal reattachment. An RR incision does not appear to influence initial anatomic repair when gas tamponade is used after vitrectomy surgery for PVR. However, RR may increase the initial surgical success rate in eyes receiving silicone oil tamponade for PVR. In eyes undergoing RR for the treatment of severe PVR, the use of silicone oil may increase the initial rate of reattachment compared with the use of gas tamponade.     

Tailored vitrectomy and laser photocoagulation without scleral buckling for all primary rhegmatogenous retinal detachments

AIM: To investigate the anatomical and functional results and the complications in eyes operated on using vitrectomy without scleral buckling for all forms of rhegmatogenous retinal detachment (RRD). METHODS: All cases of primary RRD at the University Hospital of Lund, Lund, Sweden, treated by one surgeon during a period of 3 years were retrospectively reviewed. In 131 (98%) of 134 consecutive cases, a final follow-up record of 3-14 months was obtained, and these eyes were included in the study. The surgical protocol was tailored for each case and consisted of vitrectomy, laser photocoagulation and tamponade. Preoperative and intraoperative variables were analyses for risk for redetachment and postoperative proliferative vitreoretinopathy (PVR). RESULTS: Complete reattachment was achieved in 87% of cases (114/131) after one operation and in 95% cases after > or =1 operation. A primary detachment of >1 quadrant was the only significant risk factor for redetachment (p<0.05). The most common cause of redetachment was progressive PVR. Significant risk and factors for PVR postoperatively were a poor preoperative visual acuity and a high number of laser effects during surgery (p<0.05). The visual acuity for the total number of eyes, macula-off eyes, and pseudophakic as well as phakic eyes, improved significantly. The visual acuity for macula-on eyes did not change significantly. Six patients developed ocular hypertension and another 6 an epiretinal membrane. Three patients reported a visual field defect. Increased lens opacification was seen in 64 of the 94 (68%) phakic eyes. CONCLUSIONS: The tailored vitrectomy protocol is well suited to all types of RRD. Increased lens opacification in phakic eyes is common, but visual acuity is considerably improved in phakic as well as pseudophakic eyes. PVR development postoperatively is related to the extent of laser treatment, indicating that the protocol may be even further optimised in the future.     

Primary repair of retinal detachment with 25-gauge pars plana vitrectomy

PURPOSE: To evaluate 25-gauge pars plana vitrectomy (PPV) for primary repair of rhegmatogenous retinal detachment (RRD). STUDY DESIGN AND PARTICIPANTS: This retrospective, consecutive case series included 42 eyes of 41 patients who underwent primary repair of RRD utilizing transconjunctival 25-gauge PPV without scleral buckling at the Cincinnati Eye Institute from July 2004 through January 2007. METHODS: The medical records were retrospectively reviewed, and the corresponding demographic data, preoperative ophthalmic diagnoses, surgical management, and postoperative course and treatment were recorded. Main outcome measures included single surgery anatomical success, preoperative and postoperative visual acuity, and complications. RESULTS: Most patients had pseudophakic RRD (36 [85.7%] of 42 eyes). The crystalline lens was present in the remaining 6 eyes (14.3%). Of 42 eyes, 28 (66.7%) had macula-on RRD, while 14 (33.3%) had macula-off RRD. Four surgeons contributed to this study, and 25-gauge PPV instrumentation, a wide-angle viewing system, endolaser photocoagulation, and gas tamponade were used in each case. The single surgery anatomical success rate was 92.9% (39 of 42 eyes). For eyes with macula-on RRD, best-corrected visual acuity was 20/50 (0.43 logMAR [logarithm of the minimum angle of resolution]) preoperatively and 20/30 (0.23 logMAR) postoperatively (P = 0.24). For eyes with macula-off RRD, best-corrected visual acuity was 5/200 (1.56 logMAR) preoperatively and 20/30 (0.23 logMAR) postoperatively (P = 0.001). Three eyes required additional surgery for final reattachment. Final reattachment was achieved in 100% of patients (mean follow-up, 8 months). CONCLUSIONS: Twenty-five-gauge PPV with laser retinopexy and gas tamponade is effective for primary repair of RRD. The single operation anatomical success rate is comparable with rates reported for primary vitrectomy with 20-gauge instrumentation, scleral buckling, and combined vitrectomy/scleral buckling.     

学龄期儿童独眼视网膜脱离临床特点和手术效果分析

目的：探讨学龄期儿童独眼视网膜脱离(RD)潜在病因以及RD临床特点。

方法：回顾性分析2015-11/2021-05于本院就诊的7～14岁儿童患者如下病例：患眼RD且对侧眼盲目(独眼RD)。描述并探讨其一般情况及RD病因、临床类型、手术方式、眼内填充物类型、手术前后视功能和解剖预后等。

结果：共纳入27例27眼独眼RD患者,随访至少6mo以上。平均就诊年龄为10.63±2.30岁。家族性渗出性玻璃体视网膜病变(FEVR)(11/27,41%),先天性青光眼术后(6/27,22%)和Stickler综合征(3/27,11%)为主要致病原因。其中,孔源性视网膜脱离(RRD)占78%(21/27),孔源性视网膜脱离患者(17/21)中81%的患者表现为增殖性玻璃体视网膜病变(PVR)C3及以上。共有85%(23/27)的患者行玻璃体切除术,其中83%(19/23)的患者手术中联合硅油填充。末次随访最佳矫正视力(BCVA,LogMAR)低于1.7的患者占78%(21/27),82%(22/27)的患者末次随访时视网膜平复在位,而41%(11/27)的患者末次随访时硅油尚未取出。

结论：学龄期儿童独眼RD常合并潜在的先天或遗传性眼病,且常表现为严重的RD和较重的PVR反应,多需玻璃体切除术联合硅油注入,视功能和解剖预后也较差。     

巩膜环扎术是否必须?——玻璃体视网膜手术方法的探讨

目的探讨巩膜环扎带对玻璃体手术治疗孔源性视网膜脱离(RRD)治愈率及视力预后的影响。方法回顾分析有随访纪录的以玻璃体手术治疗的孔源性视网膜脱离140例(140眼)(除去黄斑孔),按是否做巩膜环扎术分为环扎组和非环扎组。比较环扎组与非环扎组在不同增生型玻璃体视网膜病变(PVR)分级及裂孔不同位置的复位率以及两组术后视力的改善情况。结果环扎组79眼,视网膜完全复位67眼,复位率84.81%。非环扎组61眼视网膜完全复位52眼,复位率85.25%。非环扎组视网膜解剖复位率略高于环扎组,但差异无统计学意义(P>0.05)。两组在不同PVR级别以及裂孔不同位置的视网膜复位率相比差异无统计学意义(P>0.05)。术后视力改善者,环扎组63眼占79.75%;非环扎组49眼占80.33%,两组间差别无统计学意义(P>0.05)。结论有玻璃体手术指征的RRD提高玻璃体视网膜手术成功率的关键是彻底松解视网膜固定皱襞及裂孔周围的牵引,彻底地封闭所有视网膜裂孔及有效的眼内填充,巩膜环扎术并非必须。     

Scleral buckling versus primary vitrectomy in rhegmatogenous retinal detachment (SPR Study): Design issues and implications

BACKGROUND: In patients with more complex rhegmatogenous retinal detachments (RRD) not complicated by proliferative vitreoretinopathy (PVR), the most appropriate operating method is controversial, and different surgeons use different techniques. The Scleral Buckling Versus Primary Vitrectomy in Rhegmatogenous Retinal Detachments Study (SPR Study) is designed to compare primary vitrectomy and scleral buckling techniques in these patients. METHODS: The SPR Study is a multicentre, randomised, controlled clinical trial stratified by lens status. Patients with RRD which is not complicated by PVR grade B or C and which cannot be treated with a single meridional sponge are randomised to either scleral buckling or pars plana vitrectomy as first surgical intervention. Four hundred consecutive patients are to be recruited per subtrial (phakic and aphakic/pseudophakic patients), and followed up for 1 year. The primary endpoint (functional outcome) is the change in visual acuity. Secondary endpoints (anatomical outcome) include postoperative PVR, retinal reattachment and the number of reoperations necessary to achieve retinal reattachment. Twenty-seven institutions (49 surgeons) in six European countries have been recruited for participation in the study. CONCLUSION: The SPR Study is the first randomised prospective clinical trial to compare scleral buckling and primary vitrectomy in patients with RRD. The results of this study should enable vitreoretinal surgeons to improve the surgical therapy of patients with the more complicated manifestations of RRD.

Vitrectomy, lensectomy and silicone oil tamponade in the management of retinal detachment associated with choroidal detachment

AIM:To report the results of combined vitrectomy, lensectomy and silicone oil (SO) tamponade in treating primary rhegmatogenous retinal detachment (RRD) associated with choroidal detachment (CD).METHODS:A retrospective, consecutive and case series study of 21 subjects with concurrent RRD associated with CD was conducted. All subjects underwent a standard three-port 20G pars plana vitrectomy (PPV) with lensectomy and silicone oil tamponade. Mean follow-up time was 8 months (rang from 4 to 19 months). The primary and final anatomic success rate, visual acuity and final intraocular pressure(IOP) were recorded and analyzed.RESULTS:Of 21 subjects, 8 were women and 13 were men. Age at presentation ranged from 22 to 75 years (mean 57.4 years). The presenting vision ranged from light perception to 0.15. The initial IOP ranged from 3mmHg to 12mmHg (mean 6.2mmHg). All eyes were phakic except one pseudophakic. No intraocular lens was implanted during the primary surgical intervention. Fifteen of 21 (71.4%) eyes had retina reattached after one operation. Six eyes had recurrent inferior retinal detachment due to proliferation. Five of them were successfully reattached after one or more additional operations. Mean IOP at final follow-up was 15.2mmHg (range from 8mmHg to 20mmHg). One case declined for further operation. The final reattachment rate was 95.2%. Visual acuity improved in 19 (90.5%) eyes, was unchanged in 1 (4.8%) eye and decreased in 1 (4.8%) eye.CONCLUSION:Combination of vitrectomy, lensectomy and silicone tamponade is an effective method in treating RRD associated with CD, reducing the incidence of postoperative hypotony.

Primary rhegmatogenous retinal detachment: evaluation of a minimally restricted face-down positioning after pars plana vitrectomy and gas tamponade

AIM: To systematically understand the genetic association between methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and primary open angle glaucoma (POAG). METHODS: A comprehensive literature search in Google Scholar, PubMed, SCI, foreign medical literature retrieval service, CNKI and Wanfang databases was performed to collect all eligible studies up to August 2019. Study selection, data abstraction and study quality evaluation were performed by two independent investigators. The pooled odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of association. Publication bias was tested by funnel plot and Begg’s test. RESULTS: Totally 18 case-control studies involving 2156 cases and 2201 controls were retrieved. There was no evidence of significant association in the Caucasian population (for allelic model: OR=1.11, 95%CI=0.88-1.39; for additive model: OR=1.01, 95%CI=0.76-1.36; for dominant model: OR=1.15, 95%CI=0.84-1.58 and for recessive model: OR=1.02, 95%CI=0.78-1.33). However, significant associations were revealed in the Asian population (for allelic model, OR=1.34, 95%CI=1.12-1.59; for dominant model: OR=1.41, 95%CI=1.14-1.76). CONCLUSION: This Meta-analysis shows that there were significant associations between MTHFR C677T polymorphism and POAG in allelic model and dominant model for Asians subgroup indicating that the T allele or TT +TC genotype might increase the risk of POAG.

Combined pars plana vitrectomy–scleral buckle versus pars plana vitrectomy for proliferative vitreoretinopathy

The purpose of the study is to evaluate the surgical outcomes of combined pars plana vitrectomy–scleral buckle (PPV–SB) versus pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment complicated with proliferative vitreoretinopathy (PVR). One thousand one hundred and seventy four patients with rhegmatogenous retinal detachment surgery between January 2002 and December 2013 were retrospectively reviewed. Patients with grade C PVR treated with either combined PPV–SB or PPV alone were included in the study. Study outcomes included single surgery anatomic success rate and postoperative visual outcome at 12 months postoperatively. Seventy-seven patients with grade C PVR were identified for analysis. At the end of 12-month follow-up, 80.5 % eyes (33/41) in the PPV–SB group and 58.3 % eyes (21/36) in the PPV group achieved single surgery anatomical success. In a multiple logistic regression model, none of the baseline variables (age, gender, macula status, grade of PVR, extent of detachment, presence of vitreous hemorrhage, lens status, status of high myopia) nor types of retinal detachment surgery (use of scleral buckle, barrier endolaser, 360 degree endolaser, cryopexy, retinectomy, tamponade agent, phacoemulsification) had significant effect on single surgery anatomical success. The post-treatment mean logMAR visual acuity of the PPV–SB group was 1.58 ± 0.58 and the PPV group was 1.57 ± 0.61. There was no significant difference in the postoperative visual acuity between the two groups (P = 0.849). For patients with grade C PVR, PPV–SB did not demonstrate a superiority over PPV alone in achieving single surgery anatomical success.     

25G玻璃体切割术后空气与硅油填充治疗孔源性视网膜脱离的疗效比较

目的:比较25G玻璃体切割术(PPV)联合空气或硅油填充治疗孔源性视网膜脱离(RRD)的疗效。方法:前瞻性随机对照研究。收集2018-01/12经我院确诊的RRD患者146例146眼,根据25G PPV术后眼内填充物分为空气组(60例60眼)和硅油组(86例86眼)。术后随访6~12mo,分析两组患者最佳矫正视力(BCVA)、眼压、视网膜解剖复位率及并发症情况。结果:术后1mo,空气组患者BCVA为0.45±0.5,硅油组为0.78±0.65,两组患者BCVA均较术前明显改善,且空气组患者BCVA明显优于硅油组(均P<0.05)。术后3mo,空气组患者视网膜解剖复位率(93.3%)低于硅油组(97.7%),但无差异;术后6mo,两组患者视网膜解剖复位率均为100.0%。本研究纳入患者术中主要并发症是医源性裂孔(6.8%),术后主要并发症是高眼压,术后早期(7d内)硅油眼高眼压比例明显高于空气组(P<0.001),但随访期间两组患者均未出现感染性眼内炎、脉络膜出血等严重并发症。结论:对于简单新鲜的RRD患者,25G PPV术后空气和硅油填充视网膜解剖复位率无差别,术后早期空气填充眼视力优于硅油填充眼,术后高眼压发生率更低。     

Outcomes of the Perplexed Surgical Management of Retinal Detachment in Eyes with Coloboma

PurposeTo determine the anatomical and visual outcomes of retinal detachment in eyes with chorioretinal coloboma managed by pars plana vitrectomy, endolaser photocoagulation and silicone oil (SO) tamponade.MethodsRetrospective review of 29 eyes of 29 patients with retinal detachment associated with chorioretinal coloboma. All the cases were managed by vitrectomy procedures concluding with SO tamponade. Encircling band was placed based on pre-operative evaluation and/or surgeon’s discretion. Endolaser photocoagulation was applied around the peripheral retina, all around the peripheral breaks and around the colobomatous area. The outcome measures were evaluated with regard to functional and anatomical success.ResultsThe average age at the time of surgery was 21.76 ± 9.58 years (range, 10–50 years). The mean follow-up duration was 12.28 ± 4.8 months (range, 6–24 months). Primary attached retina was obtained in 21 / 29 (72.4%) eyes after single surgery. Re-detachment in 8 / 29 (27.6%) eyes which required revision surgery was the most frequent postoperative complication followed by raised intraocular pressure in 4 / 29 (13.8%) with SO in situ. Out of 29 eyes, 23 were followed up after the removal of SO. The mean duration of SO removal was 7.91 ± 3.9 months (range, 4–18 months). Implantation of encircling band, lens removal and cryotherapy provided no added advantage. At the final examination, improvement in vision was observed in 21 (72.4%) eyes and the anatomical attachment of the retina was attained in 27 (93.1%) eyes.ConclusionsComplete pars plana vitrectomy, endolaser photocoagulation along with SO tamponade is effective for retinal detachment associated with chorioretinal coloboma. This technique improves the anatomical outcome and helps in regaining significant visual acuity.     

Local dry vitrectomy combined with segmental scleral buckling and viscoelastic tamponade for rhegmatogenous retinal detachment with vitreous traction

AIM: To demonstrate combined local dry vitrectomy and segmental scleral buckling for the treatment of partial rhegmatogenous retinal detachment (RRD) with local vitreous traction in patients at high-risk for proliferative vitreoretinopathy (PVR). METHODS: Seven eyes of 7 patients were retrospectively studied, including 3 retinal dialysis and 4 retinal detachment (RD) (3 eyes with peripheral retinal hole and 1 eye with giant tear). All patients exhibited partial RD and local vitreous traction. Combined local dry vitrectomy without conventional infusion and segmental scleral buckling was performed. Viscoelastic fluid was injected into the vitreous cavity if needed. Demographic information, preoperative and post-operative complications, and outcomes were recorded. RESULTS: The mean age of the patients at presentation was 22.43±14.28y. All seven patients obtained retinal reattachment after a single surgical intervention. Post-operative visual acuities were improved in all patients. None of them developed complications, except for temporary mildly increased intraocular pressure in 2 cases. CONCLUSION: Combined local dry vitrectomy and segmental scleral buckling and viscoelastic tamponade if needed are effective for patients of RRD with local vitreous traction. The technique avoids many complications associated with regular surgery and was minimally invasive to both the external and internal eye.
