Retinal detachment is one of the acute fundus diseases that can lead to blindness. It is classified into foramen ovale, retinal detachment, retinal detachment, and retinal detachment with exudation according to the cause. The first two should be operated as soon as possible after diagnosis, while the latter treatment is mainly aimed at the original disease. The timing of TCM ophthalmology intervention: 1, for those who are not suitable for surgery in the early stage; 2, retinal detachment by surgery, the subretinal fluid does not subside; 3, after successful surgery reset, vision does not improve. For the above three cases, TCM ophthalmology can play its therapeutic advantage and can save vision to some extent.
