智能手机眼底照相是使用智能手机相机和传统的手持式间接检眼镜透镜来获得眼底图片的简单技术。这项技术是必不可少的,当图片文件的视神经,视网膜和视网膜血管是必要的,但眼底相机是不可用的。这项技术的主要优点是智能手机的广泛使用,可以在许多设置中记录黄斑和视神经的变化,这在以前是不可能的。按照这里详细说明的明确步骤,例如手机摄像头、手持透镜和患者瞳孔的正确对准,是获得没有干扰光反射和像差的清晰视网膜图像的关键。本文将首先回顾间接检眼镜和眼底照相的光学原理。然后,将说明使用智能手机记录高质量视网膜图像的分步方法。
Smartphone fundus photography is a simple technique to obtain ocular fundus pictures using a smartphone camera and a conventional handheld indirect ophthalmoscopy lens. This technique is indispensable when picture documentation of optic nerve, retina, and retinal vessels is necessary but a fundus camera is not available. The main advantage of this technique is the widespread availability of smartphones that allows documentation of macula and optic nerve changes in many settings that was not previously possible. Following the well-defined steps detailed here, such as proper alignment of the phone camera, handheld lens, and the patient's pupil, is the key for obtaining a clear retina picture with no interfering light reflections and aberrations. In this paper, the optical principles of indirect ophthalmoscopy and fundus photography will be reviewed first. Then, the step-by-step method to record a good quality retinal image using a smartphone will be explained.
