PHACOVITRECTOMY FOR PRIMARY RHEGMATOGENOUS RETINAL DETACHMENT REPAIR(Retina. 2021;41(4):753-760. )

晶状体玻璃体切除术治疗原发性孔源性视网膜脱离的回顾性研究

Purpose:To analyze the single surgery success rate and anterior segment complications related to phacoemulsification and intraocular lens implantation in a series of patients undergoing phacovitrectomy for all types of primary rhegmatogenous retinal detachment.
应用超声玻璃体切除术修复原发性孔源性视网膜脱离
Methods:We performed a retrospective interventional case series on 302 eyes undergoing phacovitrectomy for primary rhegmatogenous retinal detachment repair between November 1, 2016 and February 2, 2019 in Edmonton, Canada. Primary outcomesincluded single surgery retinal re-attachment rate and anterior segment complications. Secondary outcomes included the effects of proliferative vitreoretinopathy and macula and/or peripheral internal limiting membrane peeling on the rate of surgical success.
我们于2016 年 11 月 1 日至 2019 年 2 月 2 日在加拿大埃德蒙顿对 302 只眼进行了回顾性介入病例系列,该眼接受了晶状体玻璃体切除术以进行原发性孔源性视网膜脱离修复。主要结果包括单次手术视网膜复位率和眼前节并发症。次要结果包括增殖性玻璃体视网膜病变和黄斑和/或外周内界膜剥离对手术成功率的影响。
Results:The single surgery success rate of phacovitrectomy for all types of primary rhegmatogenous retinal detachment was 85.1%. The presence of proliferative vitreoretinopathy was associated with lower surgical success (OR 0.33, p=0.01). Macular internal limiting membrane peeling was associated with higher surgical success (OR 2.4, p=0.05). Anterior segment complications included posterior capsular opacification (28.8%), posterior synechiae (10.9%), and posterior capsular rupture (2.3%).
各种类型原发性孔源性视网膜脱离的超声玻璃体切除术单次手术成功率为85.1%。增殖性玻璃体视网膜病变的存在与较低的手术成功率相关(优势比0.33;P = 0.01)。黄斑内界膜剥离与更高的手术成功率相关(比值比2.4;P = 0.05)。前节并发症包括后囊混浊(28.8%)、后粘连(10.9%)和后囊破裂(2.3%)。
Conclusion:Phacovitrectomy is a safe and effective treatment option for the primary repair of rhegmatogenous retinal detachments. This study provides evidence to support the safe incorporation of phacoemulsification and intraocular lens implantation with retinal surgery.
晶状体玻璃体切除术是一种安全有效的治疗孔源性视网膜脱离一期修复的方法。本研究为白内障超声乳化联合人工晶状体植入术与视网膜手术的安全结合提供了依据。

本研究对302名因各种类型孔源性视网膜脱离而接受晶状体玻璃体切除术的患者进行了回顾性病例系列研究,介绍了所有相关的眼前节并发症发生率,并得出结论,原发性孔源性视网膜脱离修复的晶状体玻璃体切除术是安全有效的,提供了支持白内障超声乳化术和人工晶状体植入术与视网膜手术安全结合的证据。不足之处在于本研究的一个重要局限是回顾性设计,若是前瞻性随机试验将使有晶状体眼玻璃体切除术和有晶状体眼玻璃体切除术在原发性RRD修复中进行更有力的比较。此外,该研究缺乏术后屈光数据,屈光结果是白内障手术的重要指标,并且手术成功率和视力在最后一个时间点的比较并不能解释随访时间的不同。

Functional Relevance of Hyper-Reflectivity in Macular Telangiectasia Type 2( Invest Ophthalmol Vis Sci. 2021;62(3):6.)

高反射率在 2 型黄斑毛细血管扩张症中的功能相关性

Purpose:The purpose of this study was to quantify hyper-reflective lesions on en face optical coherence tomography (OCT) and study its functional relevance in macular telangiectasia type 2 (MacTel).
本研究的目的是量化正面光学相干断层扫描 (OCT) 上的超反射病变,并研究其在 2 型黄斑毛细血管扩张症 (MacTel) 中的功能相关性。
Design:This was a retrospective, cross-sectional cohort study.
这是一项回顾性、横断面队列研究。
Methods: Baseline image and functional data from participants of a phase II clinical trial (NCT01949324) that studied the effect of Ciliary Neurotrophic Factor in patients with MacTel were analyzed. The projection of hyper-reflectivity within different layers on OCT was used to generate an en face view and measure the en face size of hyper-reflectivity. Ellipsoid zone (EZ)-loss was additionally evaluated, and en face images were superimposed onto microperimetry sensitivity maps, allowing to estimate mean retinal sensitivity within areas displaying hyper-reflectivity and EZ-loss, respectively. Best-corrected visual acuity (BCVA) and reading speed were also analyzed.
分析了一项 II 期临床试验 (NCT01949324) 参与者的基线图像和功能数据,该试验研究了睫状神经营养因子对 MacTel 患者的影响。OCT 上不同层内超反射率的投影用于生成正面视图并测量超反射率的正面尺寸。此外还评估了椭球区 (EZ) 损失,并将正面图像叠加到微视野灵敏度图上,从而分别估计显示超反射率和 EZ 损失的区域内的平均视网膜灵敏度。还分析了最佳矫正视力 (BCVA) 和阅读速度。
Results:During 15.6 ± 7.2 months of follow-up, the AXL significantly increased from 22.8 ± 1.3 mm to 23.3 ± 1.4 mm (P < 0.001). Changes of border tissue angle and AXL showed a significant correlation only in the temporal region of elongating AXL eyes (r = –0.409; P = 0.002), but not in stable AXL eyes. Both BMOD and nasal MRW significantly increased from 1482.5 ± 153.0 to 1506.1 ± 154.6 µm and from 310.6 ± 83.2 to 324.6 ± 95.6 µm, respectively (all Ps < 0.001). The changes of BMOD and nasal MRW showed a significant positive correlation with changes of AXL in elongating AXL eyes but not in stable AXL eyes.
分析了 52 名患者的 52 只眼睛。32 只眼 (62%) 存在高反射,50 只 (96%) 眼存在 EZ 缺失。高反射率的平均病灶大小为 0.11 mm²(范围 = 0.01–0.26),EZ 损失的平均病灶大小为 0.51 mm²(范围 = 0.02–1.34),并且病灶大小密切相关(Spearman r = 0.79,P < 0.001)。尽管高反射率和 EZ 损失都与视网膜敏感度的显着降低有关,但病变之间的平均敏感度阈值差异显着(0.9 dB 对 16.3 dB;P < 0.001),表明高反射率的敏感度几乎完全丧失领域。超反射率的大小与 BCVA ( r= 0.09) 或阅读速度 ( r = -0.17)。
Conclusion:En face OCT can be used to quantify the area of hyper-reflective lesions in MacTel. Hyper-reflectivity in MacTel is associated with severe functional impairment, leading to an almost complete loss of retinal sensitivity as observed on microperimetry.
En face OCT 可用于量化 MacTel 中高反射病变的面积。MacTel 中的超反射与严重的功能障碍有关,导致在微视野测量中观察到的视网膜敏感性几乎完全丧失。

该研究发现高反射率与严重的、几乎完全丧失视网膜敏感性(“绝对暗点”)之间存在直接相关性。另一方面,显示 EZ 损失的区域与视网膜敏感性的相对降低相关。观察结果表明 EZ 的损失与总数的相关性比单独的绝对暗点大小更好。证明了 MacTel 的超反射与严重的功能障碍有关,导致视网膜敏感性几乎完全丧失。本文的创新之处在于,使用了一种量化 MacTel 超反射变化的方法。超反射病变在 OCT 上视网膜的正面视图中的投影允许与微视野数据的精确逐点相关,并量化超反射病变的正面投影大小。不足之处在于其有限的数量,且研究人群的选择标准仅考虑具有中等疾病阶段的眼睛。因此,早期和晚期的代表性不足,观察到的高反射率和疾病阶段的分布和患病率无法代表更广泛的 MacTel 人群。

Purpose:To report the safety and efficacy of a novel cell injection therapy using cultured human corneal endothelial cells (hCECs) for endothelial failure conditions via the report of the long-term 5-year postoperative clinical data from a first-in-humans clinical trial group.
应用培养角膜内皮细胞注射治疗角膜内皮衰竭的前11名患者五年随访结果
Design:Prospective observational study.
前瞻性观察研究。
Participants:This study involved 11 eyes of 11 patients with pseudophakic endothelial failure conditions who underwent hCEC injection therapy between December 2013 and December 2014.
本研究涉及 2013 年 12 月至 2014 年 12 月期间接受 hCEC 注射治疗的 11 名假晶状体内皮衰竭患者的 11 只眼。
Methods:All patients underwent follow-up examinations at 1 week, 4 weeks, 12 weeks, and 24 weeks and 1 year, 2 years, 3 years, 4 years, and 5 years after surgery. Specific corneal endothelial cell parameters (i.e., corneal endothelial cell density [ECD], coefficient of variation of area, and percentage of hexagonal cells) and central corneal thickness, best-corrected visual acuity (BCVA) on a Landolt C eye chart, and intraocular pressure (IOP) were recorded.
所有患者均于术后1周、4周、12周、24周及1年、2年、3年、4年、5年进行随访检查。特定角膜内皮细胞参数(即角膜内皮细胞密度 [ECD]、面积变异系数和六角形细胞百分比)和中央角膜厚度、Landolt C 视力表上的最佳矫正视力 (BCVA) 和眼内记录压力(IOP)。
Main Outcome Measures:The primary outcome was the change in central ECD after cell injection therapy, and the secondary outcome was corneal thickness, BCVA, and IOP during the 5-year-postoperative follow-up period.
主要结果是细胞注射治疗后中央 ECD 的变化,次要结果是术后 5 年随访期间角膜厚度、BCVA 和 IOP。
Results:At 5 years after surgery, normal corneal endothelial function was restored in 10 of the 11 eyes, the mean ± standard deviation central corneal ECD was 1257 ± 467 cells/mm.
术后5年,11只眼中有10只眼角膜内皮功能恢复正常,角膜中央ECD平均值±标准差为1257±467个细胞/mm 2(范围601-2067个细胞/mm 2),BCVA明显改善10只眼的平均视力由术前最小分辨角对数的0.876变为术后最小分辨角对数的0.046,未见与hCEC注射治疗直接相关的重大不良反应。
Conclusion
The findings in this study confirmed the safety and efficacy of cultured hCEC injection therapy for up to 5 years after surgery.本研究的结果证实了培养 hCEC 注射疗法在手术后长达 5 年的安全性和有效性。

推荐理由

由于全世界每年都存在供体角膜的持续短缺,所以一种消除这些问题的新型外科手术将是非常有益的。本文创新之处在于新的培养 hCEC 注射疗法是角膜再生医学的范式转变,具有潜在的临床应用于全球患者的潜力,本研究的结果也证实了培养 hCEC 注射疗法在手术后长达 5 年的安全性和有效性。
不足之处在于该研究注册的眼睛数量较少,只有11眼,使得该研究结果存在一定的局限性。
