美国伊利诺伊大学芝加哥分校生物工程系的Wang B等近日在Sci Rep发表了一篇文章,他们建立了一种新型的非散瞳的宽视场眼底照相机,可以实现在较少瞳孔扩张的情况下获得宽视场眼底摄影。

在传统的眼底摄影中,瞳孔间的光会通过瞳孔的周边区域将照明光传递到眼睛的内部,并且只有瞳孔中心部分可以用于收集成像光。因此,常规眼底照相机的视野受到限制。然而许多疾病需要瞳孔扩张来评估视网膜周边的情况,如糖尿病视网膜病(DR)、早产儿视网膜病(ROP)和其他脉络膜视网膜病症等。

他们在这里报道了一种非散瞳的宽视场眼底照相机,采用透射式平面照明,通过瞳孔以外的区域也可以提供照明光。因此可以在较少瞳孔扩张的情况下容易地实现宽视场眼底摄影。他们对上述理念进行了验证,制造出原型仪器,使用所有现成的组件,证明了可以在单次眼底图像中实现90°眼底视野覆盖,而不需要药理学处理使瞳孔扩张获得。
