There are many different types of fundus hemorrhages and many different types of drugs to treat them. The most common drug injected into the eye is an anti neovascular drug. This drug was initially used for tumor, but later it was found that the macula of retina, macular edema, choroidal neovascular membrane, as well as the neovascularization around diabetic retinopathy, and diabetic macular edema have better effect, so this is a common drug for fundus hemorrhage; in addition, there is another kind of hormone, which can be injected into the vitreous, often for fundus hemorrhage. It is often used for macular edema caused by fundus hemorrhage.
