A single-center, randomized, two-arm parallel-group, open-label controlled clinical trial will be conducted to determine whether the Zi-Yin-Liang-Ge-San (ZYLGS), which contains Rx. Scutellariae, Rx. Glycyrrhizae, Hb. Dendrobii, Rx. Ophiopogonis, and Hb. Menthae Haplocalycis, combined with RT can improve the incidence and severity of OM. The gene discussed is GSTM1; the disease is ocular melanoma.
