As the increasing population aging, the incidence of age-related macular degeneration is increasing, blinding rate also increasing, so it is very important for the early diagnosis and treatment of age-related macular degeneration. There are many methods to check the aging macular degeneration, such as fundus angiography, optical coherence tomography(OCT), visual field and multifocal electroretinogram(mfERG). In recent years, many emerging ophthalmic methods have emerged and are gradually applied to clinical diagnosis, including optic coherence tomography angiography(OCTA). The function of these methods has its unique advantages, but there are also limitations. This paper will review these existing methods.
