Confocal scanning laser ophthalmoscope imaging superimpose two or three kinds of lasers to obtain images of different layers of retina, and then synthesize a pseudo-color fundus image by computer. Confocal scanning laser ophthalmoscope is widely used in outpatient fundus pre-examination and epidemiological screening of large samples due to its features of non-mydriatic, fast imaging, simple operation and high degree of patient cooperation. It has good clinical and scientific application value in the diagnosis and treatment of a variety of fundus diseases. Because of there is still a lack of unified standards for laser fundus photos in China, it is necessary to correctly identify the common fundus lesions in confocal scanning laser ophthalmoscope and to summarize and popularize the method of reading the photos in layers. In addition, we should give full play to the its advantage of layering and locating, and reasonably choose the combination of OCT, OCT angiography, FFA, ICGA, ultrasonography, so as to maximize its clinical application value and help clinical diagnosis.
