简介:基因治疗是为网膜的退化疾病的潜在地有效的治疗。定期聚类interspaced短palindromic重复(CRISPR)/CRISPR-associated蛋白质9(Cas9)系统在眼的研究作为一个新编辑染色体的工具被开发了。在研究的最近的进展证明CRISPR/Cas9在在视网膜炎pigmentosa(RP)和leber的vivo产生动物模型以及基因治疗被使用了先天的黑(LCA)。它被与象联系adeno的病毒(AAV)那样的另外的技术结合也为诊所作为一次潜在的尝试显示出并且导致pluripotent干细胞(iPSCs)。在这评论,我们加亮在指向网膜的退化使用CRISPR/Cas9的进一步的前景的主要的点。我们也在治疗网膜的退化疾病强调这种技术的潜在的应用程序。
简介:AIMTo调查锰superoxidedismutase(MnSOD)的协会有糖尿病的retinopathy(医生)的Val16Ala多型性.METHODSPubMed,Embase,中国知识基础结构,和Wanfang数据库被寻找。分享的机会比率(ORs)和95%信心间隔(CI)被计算评估协会的力量。亚群,敏感,和累积分析被执行。出版偏爱也是analyzed.RESULTSEight研究在分享的分析被包括。MnSODVal16Ala多型性在主导的模型下面与医生的风险被联系(OR=0.66,95%CI=0.48-0.91,P<0.0001),这结果被表明在累积分析相对稳定。没有重要出版偏爱被发现。这多型性也在主导的模型下面在白种人与医生的风险被联系(OR=0.64,95%CI=0.42-0.97,P=0.04,)并且在在后退的模型下面的亚洲人(OR=0.31,95%CI=0.11-0.88,P=0.03).CONCLUSIONThese调查结果建议MnSODVal16Ala多型性是为医生的一个风险因素,并且更多的注意竟然对这些危险性基因的搬运人被给予。
简介:目的:探讨中西医结合治疗Vogt-小柳-原田综合征(VKH)的临床疗效。方法:对34例68眼VKH采用小剂量糖皮质激素、免疫抑制剂联合中医辨证论治治疗。结果:治愈60眼,好转4眼,总有效率94%。视力≥1.0者24眼,视力≥0.2者64眼。4眼因白内障视力〈0.2。结论:中西医结合治疗VKH可有效的控制炎症,并且可以减少糖皮质激素、免疫抑制剂的用量。
简介:目的探讨中、晚期新生血管性青光眼的治疗方法及疗效。方法对中、晚期新生血管性青光眼29例(30眼),根据屈光间质情况分成光凝组和冷凝组,分别行超全视网膜光凝或全视网膜冷凝治疗,再结合行巩膜池小梁切除术,术后观察两组患者的视力、眼压、虹膜新生血管消退情况及并发症等。结果术后随访6-18个月,平均(10.2±3.65)月。术后所有患者眼痛、头痛症状消失。光凝组16例,17眼,术后14眼眼压控制在21mmHg(1mmHg=0.133kPa)以下,手术成功率82.4%,3眼需加用药物控制后眼压〈25mmHg,术后视力提高8眼(47.1%),15眼虹膜新生血管消退,2眼部分消退,残存数根干瘪的新生血管,冷凝组:13眼,术后10眼眼压控制在正常范围,手术成功率为76.7%,2眼需加用药物治疗,1例出现眼球萎缩。术后视力提高3眼(23.1%),11例虹膜新生血管完全消退,2例部分消退。结论超全视网膜光凝或冷凝结合巩膜池小梁切除术是治疗中、晚期新生血管性青光眼的有效方法,适于基层医院开展。
简介:目的探讨前列腺素类药结合玻璃体腔注射雷珠单抗治疗新生血管性青光眼的效果。方法伴发高眼压的新生血管性青光眼患者160例根据随机数字表法分为治疗组80例与对照组80例,两组都给予复合式小梁切除术,对照组选择拉坦前列腺素辅助治疗,治疗组选择拉坦前列腺素联合玻璃体腔注射雷珠单抗辅助治疗。结果治疗后治疗组与对照组的治疗有效率分别为97.5%和88.8%,治疗组的治疗有效率明显高于对照组(P〈0.05)。两组治疗后最佳矫正视力都明显提高,而眼压都明显下降,与治疗前对比差异明显(P〈0.05);同时治疗后治疗组的最佳矫正视力与眼压也都明显好于对照组(P〈0.05)。治疗期间治疗组的眼结膜充血、前房炎症反应、角膜水肿、一过性视觉模糊等并发症发生率都明显低于对照组(P〈0.05)。所有患者治疗后随访调查6个月,治疗组的治疗后3个月与6个月的复发率分别为1.3%和5.0%,而对照组分别为7.5%和13.8%,治疗组治疗后3个月与6个月的复发率明显少于对照组(P〈0.05)。结论前列腺素类药结合玻璃体腔注射雷珠单抗治疗新生血管性青光眼能促进眼压的降低,改善视力水平,安全性好,降低复发,从而有利于近远期疗效的提高。
