Prof. LUO Xiangxia believed that"all dampness and swelling and fullness belong to the spleen", spleen qi deficiency, loss of healthy movement, and dampness trapped in the macula, causing water and dampness retention in the macula. The evil of water and dampness (water, drink and dampness are all changes of fluids, so this article collectively refers to the evil of water and dampness, without detailed investigation) enters the retina through the diseased pigment epithelium, causing detachment of the retinal neuroepithelial layer, which develops into CSC and endangers the patient's vision. Accordingly, the basic treatment method of "warming Yang and strengthening the spleen, permeating dampness and promoting water circulation" was established for spleen deficiency and dampness trapped type CSC. The treatment of this disease is based on the theory of spleen deficiency and dampness, and by following this method and combining it with the thinking of Chinese medicine, we can achieve better results and provide new ideas and strategies for clinical treatment to improve the quality of life of CSC patients.
