简介：马氏杆由一系列的平行的柱镜组成。被检查者双眼注视远处点状光源,此时在一只眼前放置马氏杆,就使该眼前点光源变成直线;而另一只眼前未放置马氏杆所见的点状光源仍为点状,从而使双眼所见物像不同。马氏杆观察眼前的点状光源就变成一条线状光,并且此条线状光的方向与组成马氏杆的柱镜长轴方向是互相垂直的。采用马氏杆加三棱镜检查出的斜视度数（包括隐斜和显斜两部分）。

简介：双眼复视患者临床评估是疾病诊断的基础。结合病史、症状与重要体征可以帮助我们定位和定性诊断。在神经眼科诊室中利用简单的马氏杆检查（Maddoxrodtest）可以初步判别眼位的偏斜及进行定量分析,用于疾病诊断及病情随访。下面我们将马氏杆的使用及判断要点介绍如下。

简介：马凡氏综合症是一种常染色体不完全外显性遗传病,临床表现多样,主要涉及心血管、骨骼和眼等系统,病死率高。对发病患者应加强健康教育、风险管理,积极治疗护理,给予心理支持。患者生育正常儿和患儿的几率各为50%,这就意味着提高正常儿出生率是医务人员为之奋斗的目标,也是马凡氏综合症患者的福音,所以,加强遗传学、优生优育教育将成为马凡氏综合症健康教育的新动向。

简介：目的：分析小儿先天性鼻泪管闭塞所致泪囊炎的病原菌及其药敏结果,指导临床合理用药。方法：对先天性鼻泪管阻塞患儿98例110眼的泪囊分泌物进行病原菌分离培养及药物敏感试验。结果：从94眼的分泌物中共分离出155株细菌,病原菌阳性率为85.5%。其中革兰氏阳性球菌65.8%,革兰氏阴性杆菌23.9%。分离出的所有菌株对左氧氟沙星的敏感率为94.2%。结论：药敏试验表明绝大多数细菌对左氧氟沙星有较高的敏感性,对于小儿先天性鼻泪管闭塞所致泪囊炎可给予新喹诺酮类抗生素滴眼液治疗。
