本文介绍一种新研制的自适应光学屈光扫描检眼镜（AO-DSO），它的光学部分全部采用折射透镜代替凹凸镜。通过设计屈光光学器件，我们能够实现具有10度视场（FOV 10）和1.5度视场（FOV 1.5）高分辨率成像的紧凑仪器。虽然由于在10度视场上眼睛像差的变化而牺牲了FOV 10的分辨率，但是我们的系统在FOV1.5的情况下与AO一起工作，并且在FOV 10的情况下可以用作具有良好光学切片的扫描激光检眼镜。为了测试AO-DSO的能力，我们对正常受试者和隐匿性黄斑营养不良患者进行了成像。
We introduce a newly developed adaptive optics dioptric scanning ophthalmoscope (AO-DSO) in which all powered optical parts were refractive lenses instead of concave or convex mirrors. By designing dioptric optics, we were able to achieve a compact instrument with a 10 deg field of view (FOV10) and 1.5 deg field of view (FOV1.5) high-resolution imaging. Although the resolution of FOV10 was sacrificed because of the variation of aberrations of the eye over the 10 deg field, our system works with AO in the case of FOV1.5 and can be used as a scanning laser ophthalmoscope with good optical slicing in the case of FOV10. To test the ability of the AO-DSO, we performed imaging on a normal subject and on a patient with occult macular dystrophy.
