雷珠单抗联合小梁切除术治疗新生血管性青光眼

目的：探讨玻璃体腔内注射雷珠单抗联合小梁切除术治疗新生血管性青光眼(NVG)的疗效。

方法：收集2015-09/2017-04我院收治的NVG患者52例52眼的临床资料行回顾性分析,根据手术方式分为A组(玻璃体腔内注射雷珠单抗联合小梁切除术,31眼)和B组(玻璃体腔内注射雷珠单抗联合Ahmed青光眼阀植入术,21眼)。术后随访6mo,比较两组患者手术前后眼压和术后视力、视野、并发症情况,并评定临床疗效。

结果：两组患者术后眼压均逐渐降低,术后7d,1、3mo时A组患者眼压均低于B组(P<0.05)。术后6mo,两组患者视力和视野改变情况无明显差异(P>0.05),但A组患者治疗总有效率显著高于B组(97% vs 71%,P=0.013)。随访期间,A组患者角膜水肿、前房积血发生率均低于B组(均P<0.05)。

结论：玻璃体腔注射雷珠单抗联合小梁切除术治疗NVG,能有效降低并维持眼压水平,减少术后并发症,疗效显著。

Intraocular inflammation after Ultrasound Cyclo Plasty for the treatment of glaucoma

This is a prospective interventional clinical study evaluating intraocular inflammation developed after Ultrasound Cyclo Plasty (UCP) for the treatment of glaucoma. Eighteen eyes of 18 patients were treated with UCP second-generation probes (Eye OP1). After treatment, the mean intraocular pressure (IOP) significantly decreased from 26.8±7.2 to 18.8±6.1 mm Hg at day 1 and to 14.7±3.4 mm Hg at month 6 (all P<0.001). Mean laser flare-cell photometry value steeply increased after surgery from 12.1±7.5 to 64.1±53.9 ph/ms (P=0.001) at day 1, and then progressively decreased to respectively 60.6±49.7 at day 7, 43.5±38.5 at day 14 and 28.2±18.3 at month 1 (all P<0.05), returning at levels similar to baseline ones at month 3 and month 6 (respectively 16.7±6.2 and 12.8±10.2, both P>0.05). A significant negative correlation was found between postoperative increase of aqueous flare values and anterior chamber depth (R=-0.568, P=0.014). This timeframe may be considered reasonable for repeating UCP treatment, when required.     

Progression on canaloplasty for primary open angle glaucoma

As a non-penetrating glaucoma surgery (NPGS), canaloplasty aims to reconstruct the physiological outflow of aqueous humor by dilating the Schlemm’s canal. Ab interno canaloplasty (ABiC), which can reconstruct the natural outflow pathways of aqueous humor in mild-to-moderate primary open angle glaucoma (POAG) patients, is a new minimally invasive glaucoma surgery (MIGS) procedure improving from traditional canaloplasty. Canaloplasty can reduce intraocular pressure (IOP) with high efficiency and security. There are no complications such as scar formation and encapsulation for this no-bleb canaloplasty.     

Association between interleukin-10 genetic polymorphisms and risk of primary open angle glaucoma in a Chinese Han population: a case-control study

AIM: To investigate the association between interleukin-10 (IL-10) genetic polymorphisms and risk of POAG through a case-control study in a Han population of China. METHODS: A total of 210 patients with POAG and 420 normal subjects were recruited during the period from Dec. 2013 to Dec. 2016. The IL-10 -1082A>G (rs1800870), -819T>C (rs1800871) and -592C>A (rs1800872) polymorphisms were determined using iPlex GOLD SNP genotyping analysis (the SequenomMassARRAY® System, Sequenom, San Diego, USA). The association between IL-10 -1082A>G (rs1800870), -819T>C (rs1800871), and -592C>A (rs1800872) polymorphisms and risk of POAG was assessed by singlelogistic regression analysis. RESULTS: We observed that those carrying the CC genotype of rs1800871 was associated with an increased risk of POAG when compared with those harboring the TT genotype (OR=1.84, 95%CI=1.01-3.38). Those with AA genotype of rs1800872 had a 10.62 fold risk of POAG in comparison to the CC genotype (OR=10.62, 95%CI, 3.41-33.09). A completely linkage disequilibrium was found between IL-10 rs1800871-rs1800872 (D’=1.00, r2=0.16). The A-C-A (OR=2.60, 95%CI, 1.48-4.58) and G-T-A (OR=2.34, 95%CI, 1.42-3.86) haplotypes were associated with an increased risk of POAG, while the A-T-C haplotype showed a decreased risk of POAG (OR=0.63, 95%CI, 0.49-0.81). CONCLUSION: Our data suggest that IL-10 rs1800871 and rs1800872 can be predictive factors for the pathogenesis of POAG in the Chinese population.     

联合激光与传统药物治疗原发性闭角型青光眼急性发作期的临床研究

目的评价激光周边虹膜成形术联合激光瞳孔成形术与传统降眼压药物治疗原发性闭角型青光眼急性发作的有效性和安全性。 方法收集2014年1月至2015年7月于邯郸市眼科医院(邯郸市第三医院)就诊的62例(68只眼)确诊为原发性闭角型青光眼首次急性发作并未做降眼压治疗患者的病例资料。其中,男性15例(17只眼),女性47例(51只眼),平均年龄(67.5±8.5)岁,所有患者眼压升高≥40 mmHg(1 mmHg＝0.133 kPa)。将入选患者采用数字表法随机分为激光组和药物组。激光组给予激光周边虹膜成形术联合激光瞳孔成形术治疗,药物组给予传统降眼压药物治疗。采用TA03型Icare眼压计测量治疗前、治疗后1 h和2 h的眼压,记录两组角膜及前房情况。以治疗后2 h眼压降至30 mmHg及以下为抢救成功,反之则为治疗失败。激光组和药物组年龄、就诊时眼压和发作时间等资料的描述采用均数±标准差表示,组间比较使用独立样本t检验;两组治疗成功率的描述采用眼数和百分比,比较采用χ²检验;两组治疗前、治疗后1 h和2 h眼压的比较采用两因素重复测量方差分析。 结果治疗后1 h激光组14只眼抢救成功,成功率为41.2%;药物组15只眼抢救成功,成功率为44.2%。治疗后2 h激光组18只眼抢救成功,成功率为52.9%;药物组20只眼抢救成功,成功率为58.2%。治疗后1 h与2 h两组间成功率无统计学意义( χ²＝0.06,0.24;P>0.05)。激光组治疗前视力为光感至0.4,治疗后1 h视力为眼前手动至0.6,治疗后2 h视力为眼前手动至0.6。药物组治疗前视力为光感至0.4,治疗后1 h视力为光感至0.8,治疗后2 h视力为光感至0.8。两组主要并发症为前房内炎症反应和角膜内皮皱褶,无眼内感染和脉络膜下暴发性出血等严重并发症。激光组治疗前、治疗后1 h和2 h平均眼压分别为(56.9±8.7)mmHg、(37.9±16.2)mmHg和(32.9±16.4)mmHg,治疗后眼压下降,与治疗前的比较差异有统计学意义(t＝6.02,7.76;P<0.05)。药物组治疗前、治疗后1 h和2 h平均眼压分别为(55.8±9.5)mmHg、(37.6±17.7)mmHg和(30.6±18.2)mmHg,治疗后眼压下降,与治疗前的比较差异有统计学意义(t＝5.28,7.16;P<0.05)。但两组各时间点的眼压比较均无统计学意义(t＝0.89,0.58,0.85;P>0.05)。 结论激光周边虹膜成形术联合激光瞳孔成形术和传统的降眼压药物治疗均能快速降低原发性闭角型青光眼急性发作期的眼压,但激光治疗安全、有效,可避免药物治疗给机体带来的副作用,是治疗原发性闭角型青光眼急性发作期的重要辅助措施。     

微信干预对青光眼患者体力活动量的影响

观察利用微信干预增加青光眼患者体力活动的效果。方法：前瞻性随机对照研究。选择2018年 6-12月于温州医科大学附属眼视光医院门诊确诊的青光眼患者102例作为研究对象。利用Excel生成的随机数随机分为对照组和干预组。对照组患者仅在门诊入组时进行运动宣教,并告知其可增加每天的运动步数;干预组患者入组时进行运动宣教,告知其可增加每天的运动步数的同时,加入微信群进行运动提醒干预。所有患者均需利用运动监测仪器完成基线1周和随访1个月的体力活动监测。采用卡方检验、独立样本t检验、Mann-Whitney U检验、配对t检验及Wilcoxon符号秩检验进行数据分析。结果：排除30例基线运动量较大（步数>12 000步/d）、依从性不好及其他原因失访的患者,最终纳入72例（对照组42例,干预组30例）。干预组患者干预后的步数（t=4.94,P<0.001）,运动消耗的卡路里（Z=-2.87,P=0.004）,代谢当量（Z=-3.30,P=0.001）,中等强度体力活动时间（Z=-2.89, P=0.004）,高强度体力活动时间（t=2.57,P=0.016）及中高强度体力活动时间（Z=-3.01,P=0.003）均较基线增加;轻度体力活动时间（t=-2.14,P=0.041）和久坐静止不动次数较干预前减少（t=-2.76, P=0.022）。对照组随访的步数也较基线增加（t=3.29,P<0.001）,轻度体力活动时间较基线减少（t=-2.57,P=0.014）。另外,干预组的高强度体力活动时间增加量（随访-基线）（Z=-3.04,P=0.002）和超高强度体力活动时间增加量（Z=-2.06,P=0.040）明显高于对照组,差异均有统计学意义。结论：微信干预可以增加青光眼患者的每天运动步数和中高强度体力活动时间,减少患者的轻度体力活动时间和久坐静止次数。     

Discriminating performance of macular ganglion cell-inner plexiform layer thicknesses at different stages of glaucoma

AIM: To determine the discriminating performance of the macular ganglion cell-inner plexiform layer (GC-IPL) parameters between all the consecutive stages of glaucoma (from healthy to moderate-to-severe glaucoma), and to compare it with the discriminating performances of the peripapillary retinal nerve fiber layer (RNFL) parameters and optic nerve head (ONH) parameters. METHODS: Totally 147 eyes (40 healthy, 40 glaucoma suspects, 40 early glaucoma, and 27 moderate-to-severe glaucoma) of 133 subjects were included. Optical coherence tomography (OCT) was obtained using Cirrus HD-OCT 5000. The diagnostic performances of GC-IPL, RNFL, and ONH parameters were evaluated by determining the area under the curve (AUC) of the receiver operating characteristics. RESULTS: All GC-IPL parameters discriminated glaucoma suspect patients from subjects with healthy eyes and moderate-to-severe glaucoma from early glaucoma patients (P<0.017, for all). Also, minimum, inferotemporal and inferonasal GC-IPL parameters discriminated early glaucoma patients from glaucoma suspects, whereas no RNFL or ONH parameter could discriminate between the two. The best parameters to discriminate glaucoma suspects from subjects with healthy eyes were superonasal GC-IPL, superior RNFL and average c/d ratio (AUC=0.746, 0.810 and 0.746, respectively). Discriminating performances of all the parameters for early glaucoma vs glaucoma suspect comparison were lower than that of the other consecutive group comparisons, with the best GC-IPL parameters being minimum and inferotemporal (AUC=0.669 and 0.662, respectively). Moreover, minimum GC-IPL, average RNFL, and rim area (AUC=0.900, 0.858, 0.768, respectively) were the best parameters for discriminating moderate-to-severe glaucoma patients from early glaucoma patients. CONCLUSION: GC-IPL parameters can discriminate glaucoma suspect patients from subjects with healthy eyes, and also all the consecutive stages of glaucoma from each other (from glaucoma suspect to moderate-to-severe glaucoma). Further, the discriminating performance of GC-IPL thicknesses is comparable to that.     

中药及针刺对青光眼视功能的影响

目的观察滋补肝肾中药加针刺对于青光眼视功能损害的治疗效果。方法回顾性病例研究。中医辨证为肝肾阴虚证的原发性视功能损害患者38例（72只眼）,药物或手术控制眼压稳定,分为中药加针刺组15例（28只眼）、中药组12例（23只眼）、对照组11例（21只眼）,分别予口服滋补肝肾中药联合针刺、口服滋补肝肾中药和仅监控眼压处理。观察6个月,比较各组治疗前后视力、视野变化情况。结果中药加针刺组的视力、视野均较治疗前有统计学意义的改善（P〈0．05）。中药组视力未见明显变化（P〉0．05）,视野评分较治疗前下降（P〈0．05）。对照组视力和视野评分均下降（P〈0．05）。结论滋补肝肾中药联合针刺治疗对于眼压已控制的青光眼的视功能有一定的保护作用。     

激素性青光眼房水排出阻力增加的机制探讨

目的:本研究通过观察经地塞米松处理前后培养的人小梁细胞的变化,探讨激素性青光眼房水排出阻力增加的机制。方法:将人类小梁细胞培养至接近体内的高分化状态,用地塞米松处理后,观察细胞形态的变化,并检测以下蛋白的分布和表达:(1)myocilin/TIGR蛋白;(2)纤连蛋白;(3)肌动蛋白交联网的形成;(4)血清淀粉样物质A蛋白。结果:人小梁细胞经地塞米松处理后(1)胞体变大,排列不规则,边界模糊,呈"融合"状;(2)细胞内外myocilin/TIGR蛋白表达均明显增加,其胞外表达与纤连蛋白位置一致,提示相互作用;(3)纤连蛋白表达增加;(4)CLANs形成,细胞间连接增强;(5)血清淀粉样物质A蛋白表达增加。结论:人类小梁细胞经地塞米松处理后形态发生变化,可能与应力纤维变化及myocilin蛋白在细胞内积聚有关。细胞间边界不清,与细胞外基质蛋白过度表达、沉积有关。小梁细胞外基质沉积以及异常的细胞间连接等改变与房水排出阻力增加的病理过程有关。
