欧堡全景200Tx激光扫描检眼镜在白内障术后患者眼底检查中的应用

目的:研究欧堡全景200Tx激光扫描检眼镜(简称Optomap 200Tx)在白内障术后患者早期眼底筛查的应用价值。方法:对2013-11-18/12-31来我院就诊的白内障患者146例161眼,均为连续病例,于术后1wk行非散瞳下直接检眼镜检查、非散瞳下Optomap 200Tx检查、散瞳后裂隙灯下前置镜检查,并对三种检查方法进行对比。结果:患者146例161眼行非散瞳下直接检眼镜检查、非散瞳下Optomap 200Tx检查、散瞳后前置镜检查分别发现眼底病变40眼(24.8%),59眼(36.7%),61眼(37.9%),需要及时治疗病例9眼(5.6%)。非散瞳下Optomap200Tx检查结果与散瞳后前置镜检查结果相似,差异无统计学意义,优于非散瞳下直接检眼镜检查,差异有统计学意义(P<0.05)。结论:白内障患者术前屈光间质混浊,无法详查眼底,故应常规对白内障术后患者行全面眼底筛查。Optomap 200Tx是白内障术后早期眼底筛查的一项有效、便捷的检查手段,与散瞳后裂隙灯下前置镜检查有相似检出率。

Optos 200Tx广角眼底血管造影及其临床应用

广角眼底血管造影是近年来的影像检查新技术,可用于病变范围过大、传统眼底血管造影难以覆盖的患眼,可直观地显示周边部视网膜、脉络膜的血管结构.广角眼底血管造影分为接触式和非接触式两种.近期投入使用的欧堡全景200Tx激光扫描眼底成像系统（Optos 200Tx）是非接触式广角眼底血管造影的代表.它一次即可观察到200°眼底,无需散大瞳孔,且不接触患眼,操作简单、高效而安全,可用于累及周边部眼底的血管性疾病的诊断、鉴别诊断、治疗及随访方案的制定,如糖尿病视网膜病变、视网膜静脉阻塞、视网膜血管炎、葡萄膜炎、眼底肿瘤等.

Ultra-wide field imaging system and traditional retinal examinations for screening fundus changes after cataract suraery

AIM：To compare the results of non-mydriatic ultra-wide field imaging system,mydriatic slit-lamp lens（Volk＋90 D） and mydriatic Goldmann three-mirror contact lens examinations in screening fundus lesions among patients after cataract surgery.METHODS：Non-mydriatic images were obtained with an Optomap panoramic 200Tx（Optomap 200Tx） 3d after surgery and graded by a blinded ophthalmologist.A mydriatic slit-lamp lens examination was performed by another blinded retinal specialist on the same day.A third blinded retinal specialist examined patients two weeks after surgery using a Goldmann three-mirror contact lens.RESULTS：In total,160 patients（184 eyes） were examined,and 66,69,and 75 cases of retinal lesion（s）were identified using the Optomap 200 Tx,slit-lamp lens,and Goldmann three-mirror contact lens,respectively.In13 cases,fundus changes were sight-threatening.The results obtained by Optomap 200 Tx examination and by mydriatic slit-lamp lens examination have good consistency（P =0.375,Kappa =0.942）.The mydriatic Goldmann three-mirror lens examination revealed more fundus lesions but are consistent with Optomap 200Tx（P=0.004,Kappa =0.897） and mydriatic slit-lamp lens examination（P=0.031,Kappa=0.932）.CONCLUSION：Early post-operative fundus screening in cataract patients is extremely important and necessary to prevent further vision loss.Wide-field imaging is a feasible and convenient tool for fundus examination that can be used as a primary screening method among patients after cataract surgery.

TX200/600纵横制交换机故障分析仪通过成都铁路局技术鉴定

由西昌铁路分局攀西实业总公司珠海工贸公司新技术应用开发部主持研制,铁道部第二勘测设计院协助完成的TX200/600纵横制交换机故障分析仪,于1992年5月27日通过成都铁路局技术鉴定。 该仪器除有记录、监测功能外,还具有分析功能及用户线运用状况监测的特殊功能。能判断故障所在的链路,一旦故障确认后,能按组群图分析并自动打印故障点的位置和重接状况,在密地和安顺机械室安装试用一年多时间,提高了接通率,充分发挥了交换机的使用效率。
