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。     

3D手术视频系统在PDR合并牵拉性视网膜脱离手术中的应用

目的：评价3D手术视频系统在增生性糖尿病视网膜病变(PDR)合并牵拉性视网膜脱离(TRD)玻璃体切除术中的应用效果。

方法：回顾性分析2018-08/2019-03于我院行25G微创玻璃体切除术的PDR合并局部TRD(无牵拉性视网膜裂孔)患者32例38眼的临床资料,根据术中采用的观察系统进行分组,试验组16例19眼采用3D手术视频系统手术,对照组16例19眼采用传统显微镜手术。记录两组患者手术时间、术中医源性视网膜裂孔和硅油注入情况。术后至少随访6mo,观察最佳矫正视力及术后并发症发生情况。

结果：试验组术中发生医源性视网膜裂孔1眼,硅油注入1眼; 术后视网膜均完全复位; 术后1d玻璃体出血4眼,2～4wk后自行吸收; 术后2wk内发生高眼压6眼,药物治疗均能控制; 术后6wk后玻璃体再出血2眼; 术后6mo最佳矫正视力0.3以上者15眼。对照组术中发生医源性视网膜裂孔4眼,硅油注入5眼; 术后视网膜均完全复位; 术后1d玻璃体出血6眼,2～4wk后自行吸收; 术后2wk内发生高眼压5眼,药物治疗均能控制; 术后6wk后玻璃体再出血3眼; 术后6mo最佳矫正视力0.3以上者14眼。所有患者手术均顺利完成,均无眼内炎等严重并发症发生,但试验组手术时间明显短于对照组(37.3±4.8min vs 41.2±5.1min,P=0.020)。

结论：3D手术视频系统在PDR合并TRD玻璃体切除术中的应用能够缩短手术时间,提高手术效率。     

黄斑部视网膜浅层毛细血管密度对特发性黄斑裂孔患者术后裂孔愈合的影响

目的　观察特发性黄斑裂孔患者手术前后黄斑部视网膜浅层毛细血管密度的变化,寻找各变化量之间的相关性及对术后裂孔愈合情况的影响。方法　前瞻性病例对照研究。纳入2019年8月至2020年6月就诊于海南医学院第一附属医院眼科10例确诊为特发性黄斑裂孔的患者作为黄斑裂孔组,收集13位年龄性别匹配的正常视力健康人作为对照组。黄斑裂孔组行玻璃体切割联合内界膜剥离及填塞术。对照组、黄斑裂孔组术前、术后1个月行黄斑区光学相干断层扫描（optical coherence tomography,OCT）及光学相干断层扫描血管成像（optical coherence tomography angiography,OCTA）检查。将术后愈合类型分为U型、V型、不规则型和不愈合型4种类型。观察两组术前和术后黄斑区视网膜浅层毛细血管密度变化及组间差异;并探索和术后裂孔愈合类型的相关性。结果　黄斑裂孔组术前、术后与对照组之间视网膜浅层毛细血管长度密度（retinal vessel densities of the superficial capillary plexus,VSCP）差异均无统计学意义（均为P>0.05）。黄斑裂孔组术后颞侧视网膜浅层毛细血管灌注密度（retinal perfusion densities of the superficial capillary plexus,PSCP）较术前变小,差异有统计学意义（P<0.05）,其余象限PSCP与术前差异均无统计学意义（均为P>0.05）;黄斑裂孔组术前、术后PSCP较对照组均减小,差异均有统计学意义（均为P<0.05）。黄斑裂孔组术前PSCP和术后PSCP呈正相关（r=0.721,P<0.05）。裂孔愈合类型和术后PSCP有相关性（r=-0.737,P<0.05）,和术后VSCP无相关性（r=-0.533,P>0.05）。结论　PSCP比VSCP更能反映黄斑部视网膜解剖结构的变化和术后裂孔愈合的情况;术后PSCP越大,裂孔愈合形态越接近U型愈合,可以将PSCP用于评价和预测术后裂孔的愈合情况。

Effect of Foveal Pit Restoration in Foveal Avascular Zone after Surgery for Idiopathic Epiretinal Membrane

PurposeTo investigate the relationship between ophthalmic parameters—including optical coherence tomography (OCT) and OCT angiography findings—and foveal pit restoration in eyes that had undergone vitrectomy for idiopathic epiretinal membrane (iERM) removal.MethodsThis study retrospectively analyzed data of patients who underwent pars planar vitrectomy for the removal of epirentinal membrane. Only eyes with iERM above stage 2 with a follow-up over 6 months were included. Baseline data and changes in ophthalmic parameters were analyzed from 3 months before to 12 months after surgery. Additionally, we stratified iERM patients into two groups (foveal pit restoration and no restoration group). Longitudinal comparison analyses between the two groups were done in best-corrected visual acuity (BCVA), central foveal thickness (CFT) and foveal avascular zone (FAZ) areas measurements using swept-source OCT and OCT angiography.ResultsForty-three patients with a mean age of 75 ± 5 years were enrolled. After surgery, BCVA, FAZ, and CFT showed improvements over time (all p < 0.002). Thirty-one patients were designated into the foveal pit restoration (R) group and 12 patients into the no restoration (NR) group. Differences in BCVA and FAZ area in both groups existed up to 6 months. However, BCVA improved and FAZ expanded (R, 0.20 ± 0.05 vs. NR, 0.18 ± 0.04) in both groups showing no statistical difference 12 months postsurgery. The CFT decreased in both groups, but the R group was thinner at every point compared to the NR group (all p < 0.05).ConclusionsThe removal of epirentinal membrane in pars planar vitrectomy significantly improves BCVA, decreases the CFT and expands the FAZ. Foveal pit restoration improves BCVA, CFT, and FAZ area possibly at a faster rate in the early months but long-term improvements could be achieved regardless of the status of foveal pit restoration.
