Outcomes of 25-gauge pars plana vitrectomy for cytomegalovirus retinitis-related retinal detachment

Purpose:The purpose of this study is to evaluate the anatomical and functional outcomes of 25-gauge (G) pars plana vitrectomy (PPV) in patients with cytomegalovirus retinitis (CMVR)-related rhegmatogenous retinal detachment (RRD).Methods:Single-center retrospective consecutive case series of patients who underwent 25-G PPV for CMVR-related RRD repair with a minimum follow-up of 3 months. Complete anatomic success was defined as the complete attachment of retina including the periphery. Best-corrected visual acuity (BCVA) of ≥20/400 was defined as functional success.Results:Sixteen eyes of 15 patients were included in the study. Eleven patients were human immunodeficiency virus positive, three patients had hematological malignancies, and one patient suffered from dyskeratosis congenita. The mean follow-up was 20.5 ± 17.4 months (range 3–60 months). Complete anatomical success was seen in 15 eyes (93.75%). One eye had a residual inferior detachment with attached macula. Silicone oil was used as tamponade in 15 eyes and C₃F₈ gas in one eye. The mean change in BCVA was statistically significant, preoperative LogMAR BCVA was 2.05 ± 0.94 while the final follow-up postoperative LogMAR BCVA was 1.03 ± 0.61 (P < 0.001). Thirteen eyes (81.25%) had final BCVA ≥20/400.Conclusion:Microincision vitrectomy surgery can achieve excellent retinal reattachment rates in post-CMVR RRDs without significant intraoperative and postoperative complications. The visual outcome varies depending on the status of the optic disc and macula. Majority of the patients maintained functional vision.

Epiretinal membrane following pars plana vitrectomy for rhegmatogenous retinal detachment repair

AIM: To determine the rate and possible contributors for post-pars plana vitrectomy (PPV) epiretinal membrane (ERM) in patients treated for rhegmatogenous retinal detachment (RRD). METHODS: This prospective, nonrandomized study comprised 47 consecutive patients (47 eyes) with acute RRD treated with 23 G post-PPV. All participants were followed prospectively for 6mo for the development of ERM using spectral domain optical coherence tomography. Preoperative and intraoperative data were collected by questionnaires to surgeons. Main outcome measure was the percentage of the ERM formation following post-PPV for RRD. RESULTS: ERM developed postoperatively in 23 eyes (48.9%), none necessitated surgical removal. There was a statistically significant difference between patients with and without ERM postoperatively in preoperative best corrected visual acuity (median logMAR 1.9 vs 0.3, respectively; P=0.003) rate of macula-off (69.6% vs 37.5%, respectively, P=0.028), and rate of ≥5 cryo-applications (55.6% and 18.8%, respectively, P=0.039). ERM developed mainly between the 1st and 3rd months of follow-up. Macula-off status increased the risk of ERM, with the odds ratio of 3.81 (P=0.031). CONCLUSION: ERM is a frequent post RRD finding, and its development is associated with macula-off RRD.     

Primary 23-gauge vitreoretinal surgery for rhegmatogenous retinal detachment

AIM: To report the effectiveness and safety of primary 23-Gauge (G) vitreoretinal surgery for rhegmatogenous retinal detachment (RRD). METHODS: In this retrospective study, 49 eyes of 49 consecutive patients who underwent primary 23-G transconjunctival sutureless vitrectomy (TSV) for RRD between January 2007 and July 2009 at our institution were evaluated. RESULTS: Mean follow-up time was 8.9±7.7 months (1-28 months). Retinal reattachment was achieved with a single operation in 47(95.9%) of 49 eyes. In two eyes (4.1%), retinal redetachment due to new breaks was successfully treated with reoperation using the 23-G TSV system. Mean logMAR visual acuity was 2.01±0.47 preoperatively and 1.3±0.5 postoperatively (P<0.001, Paired t-test). Mean preoperative intraocular pressure (IOP) was 14.1±2.8mmHg. Mean postoperative IOP was 12.3±3.6mmHg at 1 day, 13.1±2.1mmHg at 1 week, 14.3±2.2mmHg at 1 month. Iatrogenic peripheral retinal break was observed in 1 eye (2.0%) intraoperatively. No sutures were required to close the scleral or conjunctival openings, and no eyes required convertion of surgery to 20-G vitrectomy. CONCLUSION: Primary 23-G TSV system was observed to be effective and safe in the treatment of RRD.     

孔源性视网膜脱离玻切术前超声生物显微镜检查结果分析

目的：分析因孔源性视网膜脱离需行玻璃体切除手术的患者术前超声生物显微镜( UBM )的检查结果,探讨术前超声生物显微镜检查的临床应用价值。
　　方法：选取我院2014-01/12因孔源性视网膜脱离行玻璃体切除手术的患者,记录其术前UBM检查的结果,并对阳性结果进行分析,探讨术前应用UBM检查的价值。
　　结果：接受玻璃体切除手术的孔源性视网膜脱离患者共356例357眼。术前均进行了 UBM 检查,其中122眼(34.17%)有阳性发现,56眼有睫状体脉络膜脱离,28眼有房角狭窄,6眼房角关闭,28眼发现有睫状体囊肿,4眼发现有虹膜囊肿,11眼发现有前部增殖性玻璃体视网膜病变,1眼发现有视网膜囊肿,其中12眼同时存在两种病变。本研究中 UBM 发现脉络膜脱离者56眼,阳性率15.7%;术前眼B超检查发现脉络膜脱离者25眼,阳性率7.0%,差异有统计学意义(χ2=13.382,P<0.05)。
　　结论：对于患孔源性视网膜脱离,因病情需行玻璃体切除术的患者,术前检查UBM能够全面了解前房角、睫状体和前部脉络膜视网膜的情况,对全面了解患者术前情况,估计手术难度,指导术中操作及术后随访有重要意义。     

23G微创玻璃体切割术在孔源性视网膜脱离中的应用

目的：评估23G经结膜无缝线玻璃体切割手术治疗孔源性视网膜脱离的安全性及有效性。 方法：前瞻性选择2010-03/2011-06共26例26眼不伴有严重增生性病变的孔源性视网膜脱离病历,均行23G切割手术。记录术前、术后的最佳矫正视力（BCVA）、眼压,术中及术后并发症。 结果：一次性复位视网膜21例（81%）,最终复位视网膜25例（96%）。术后3mo最佳矫正视力较术前提高21例（80%）,不变3例（12%）,下降2例（8%）。术后1d眼压较术前下降,此差异有统计学意义（P<0.01）。低眼压（≤6mmHg）2例,持续2wk,但未发生脉络膜脱离。 结论：23G手术治疗孔源性视网膜脱离解剖复位率满意,术后视力改善明显。但23G微创手术的优势并没有在孔源性视网膜脱离的手术中得到充分体现,反而要面临更高的手术失败的风险。     

Air tamponade and without heavy liquid usage in pars plana vitrectomy for rhegmatogenous retinal detachment repair

AIM: To report the results of rhegmatogenous retinal detachment (RRD) repair after pars plana vitrectomy (PPV) without operative use of heavy liquid, and utilizing air tamponade in selected cases. METHODS: RRD patients without severity of proliferative vitreoretinopathy C2 or more underwent PPV without operative use of heavy liquid, and utilizing air tamponade were consecutively enrolled. Alternative postoperative facedown position or lateral position was required for 3-5d. RESULTS: Totally 36 eyes of 36 patients (24 males, 66.7%) aged 53.8±10.9y underwent this modified surgery. The mean number of retinal break was 2.1±1.3. Most of the eyes (29, 80.6%) had retinal detachment involving more than one quadrant. Twenty-two (61.1%) eyes with cataract had combined phacoemulsification and intraocular lens implantation. The mean follow up time was 4.6±1.8mo. Two eyes with retinal redetachment underwent a second retinal repair surgery with silicone oil tamponade, yielding the primary reattachment rate to 94.4% (34/36). Six (16.7%) eyes had intraocular pressure higher than 25 mm Hg. The visual acuity (logMAR) improved from 0.98±0.74 preoperatively to 0.52±0.31 postoperatively (P<0.001). CONCLUSION: The success rate of this modified retinal repair surgery is comparable with traditional surgery. This technique can be considered for certain retinal detachment patients, since its apparent advantages included lower surgical complications, reduced surgery expenditure, shorter time for postoperative facedown position, and avoiding silicone oil removal surgery.

25-gauge, sutureless vitrectomy and standard 20-gauge pars plana vitrectomy in idiopathic epiretinal membrane surgery: a comparative pilot study

Background The aim of the study was to evaluate the safety and functional outcome of a small incision, sutureless vitrectomy in the treatment of idiopathic epiretinal membranes (ERM) compared with a standard 20-gauge vitrectomy system.Methods Forty-six consecutive patients with idiopathic ERM were recruited for this study and prospectively evaluated. In group 1 (n=26) we used a transconjunctival sutureless 25-gauge vitrectomy system (TSV), patients in group 2 (n=20) were operated on using a standard 20-gauge vitrectomy system. The ERM was removed and the internal limiting membrane (ILM) was peeled in all eyes. Surgery-related complications, operating time, intraoperative balanced salt solution (BSS) consumption, postoperative discomfort, postoperative intraocular inflammation, lens opacification, and long-term visual outcome are reported and compared.Results No surgery-related complications were observed in either group. Operating time was shorter in group 1 compared with group 2 (mean 15.6 and 29.6 min respectively). Intraoperative amount of BSS consumption was less in group 1 (mean 28 ml in group 1 and 42 ml in group 2). Postoperative discomfort and intraocular inflammation were significantly reduced in the 25-gauge group. In the 20-gauge group cataract formation requiring surgery was observed in two eyes. Visual acuity improved significantly in both groups. The 25-gauge group improved on average by more lines of vision and the improvement in vision was more rapid.Conclusion The TSV system is a safe and efficient surgical technique for ERM surgery. Operating time is significantly reduced, minimizing surgery-induced trauma, and reducing postoperative intraocular inflammation and the patients’ discomfort. The incidence of cataract formation may be less using TSV. Postoperative recovery is accelerated.The authors have no financial interests related to this publication.     

Rhegmatogenous retinal detachment associated with massive spontaneous suprachoroidal hemorrhage and prognosis of pars plana vitrectomy

AIM:To describe the clinical characters of rhegmatogenous retinal detachment (RRD) associated with massive spontaneous suprachoroidal hemorrhage (SSCH). To evaluate optimal timing and prognosis of pars plana vitrectomy.METHODS: A retrospective review of 6 cases (6 eyes) of RRD and massive SSCH among 3772 cases of RRD was conducted. All of 6 patients were treated with twenty-gauge vitrectomy, suprachoroidal blood drainage, phacoemulsification (PHACO) or lensectomy and silicon oil tamponade. The clinical characters, intraoperative findings and treatment outcomes were reported.RESULTS: In the 6 affected eyes of 6 patients (3 men and 3 women; mean age, 53.83y; range 34-61y), preoperative visual acuity ranged from faint light perception (LP) to counting finger (CF). The average interventional duration from visual decreased to surgery was 12.8 d (range 9-15d). All eyes were associated with high myopia and the mean ocular length was 30.32 mm (range 28.14-32.32 mm). Choroidal hemorrhage were successfully drained in the operation of all 6 eyes. Intraoperative findings showed there were multiple retinal breaks in all 6 eyes and in 4 eyes breaks were along supratemporal and/or infratemporal retinal vascular arcade, especially in the edge of chorioretinal atrophy areas. These patients were followed up from 6 to 34mo (Mean, 23.5mo). The best-corrected visual acuity after surgery varied from CF to 20/100, with improvement in 5 eyes (83.33%) and no change in 1 eye (16.67%). Ocular hypertension ocurred in 1 eye (16.67%), which was successfully treated by silicon oil removal combined with trabeculectomy. In 4 eyes, tractional retinal detachment caused by proliferative vitreoretinopathy (PVR) appeared and a secondary surgery of pre-retinal membrane peeling and silicon oil retained were performed. In 4 eyes, silicon oil cannot be removed. The initial and final reattachment rates were 33.33% and 66.67%, respectively.CONCLUSION: RRD associated with massive SSCH is an extremely rare event. The most common risk factor is long axial length. Vitrectomy and choroidal blood drainage can effectively remove suprachoroidal hemorrhage and promote retinal reattachment in these eyes. However, silicon oil could not be removed in most eyes and final visual acuities are generally poor.

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。     

The incidence and the risk factors for iatrogenic retinal breaks during pars plana vitrectomy

Purpose

To establish the frequency and the risk factors for iatrogenic retinal breaks during three-port pars plana vitrectomy (PPV).

Methods

A total of 2471 PPV operations were included in the study. The study period was between 2001 and 2010, all the data were entered in an electronic patient record database. All 270 consecutive eyes of 270 patients developing iatrogenic retinal breaks during primary PPV were matched to 270 controls. Univariate and multivariate analysis were performed to establish the risk factors.

Results

The median age of the patients with iatrogenic breaks was 60.06 years; male to female ratio was 140/130. The overall frequency of iatrogenic retinal breaks was 10.09%. The frequency of iatrogenic retinal breaks for eyes undergoing PPV for tractional retinal detachment (TRD) was 32.45%. The lens status was phakic in 79.6% of the eyes, with iatrogenic breaks compared with 34.4% of the eyes in control group (P<0.001). Posterior vitreous was attached in 58.9% of the eyes with iatrogenic breaks compared with 50.4% of the eyes in control group (P=0.04). Internal limiting, epiretinal, proliferative, or fibrovascular membrane removing manoeuvers were performed in 71.1% of the eyes with iatrogenic breaks compared with 61.9% of the eyes in control group (P=0.052).

Conclusion

Eyes undergoing PPV for TRD had significantly higher frequency of iatrogenic retinal breaks compared with other subgroups (P=0.0001). Phakia and absence of PVD were found to be risk factors for iatrogenic retinal breaks.     

Changes in axial length after vitrectomy for rhegmatogenous retinal detachment combined with choroidal detachment

AIM: To report the postoperative axial length (AL) changes in rhegmatogenous retinal detachment combined with choroidal detachment (RRD-CD) patients. METHODS: The medical records of 97 consecutive patients from January 2015 to December 2018 were reviewed. Patients included were divided into RRD-CD and RRD only groups. All patients had received AL measurements before pars plana vitrectomy (PPV) and before silicone oil removal (SOR). The changes in AL of the two groups were compared. In addition, the potential factors related to AL changes were analyzed. RESULTS: AL elongation after PPV was 1.01 mm [interquartile range (IQR): 0.37, 1.79; P=0.02] in the RRD-CD group, which was greater than in RRD only group (0.15 mm, IQR: 0.04, 0.41; P<0.001). AL increased 0.06 mm per 1 mm Hg intraocular pressure changes in the RRD-CD group (R2=0.11, P=0.03). RRD-CD patient was 11.42 times (3.54-46.80) more likely to experience post-PPV AL elongation of more than 1 mm [P<0.001, Akaike information criterion (AIC)=92.33, area under the curve (AUC)=0.839]. CONCLUSION: RRD-CD patients are very likely to have a postoperative elongation of AL. The primary intraoclular lens implantation using presurgery AL data may cause a significant refractive error in RRD-CD patients who underwent PPV.     

视网膜脱离患者玻璃体切除硅油填充术后3天高眼压发生率及危险因素

目的 探讨玻璃体切除及硅油填充术治疗视网膜脱离术后3天内眼压升高的发生比例及危险因素。设计 前瞻性病例系列。研究对象 2018年2-8月北京大学第三医院连续行玻璃体切除术联合硅油填充术治疗的视网膜脱离患者135例。方法  使用回弹式眼压计测量患者术后2、4、6~8小时、1、2、3天的眼压。任何时间眼压≥25 mmHg定义为眼压升高。生存期定义为从玻璃体切除术结束至第一次眼压≥25 mmHg发生时的时间间隔（小时）。采用Cox回归分析评估术后3天内发生高眼压的相关危险因素。采用Kaplan-Meier生存曲线可视化不同病因的视网膜脱离患者的生存概率。主要指标 高眼压发生率及危险因素。结果 135例患者中44例（32.6%）发生眼压升高,眼压升高在术后第1天发生率最高（20.2%）。Cox分析显示视网膜脱离的病因与眼压升高显著相关（P=0.006）,以原发性孔源性视网膜脱离作为对照,糖尿病性牵引性视网膜脱离和复发性视网膜脱离发生眼压升高的风险分别为3.5 倍（P=0.002,HR=3.41） 和3倍 （P=0.010,HR=2.91）。糖尿病牵引性视网膜脱离和复发性视网膜脱离的总生存率显著低于原发性视网膜脱离和外伤性视网膜脱离（P<0.05）。结论 视网膜脱离患者行玻璃体切除硅油填充术后3天内眼压升高比例约占1/3,主要发生在术后第1天。对于玻璃体切除硅油填充眼特别是糖尿病牵引性视网膜脱离及复发性视网膜脱离者,术后第1天复查仍有必要性。（眼科,2022,31：27-32）
