Fundus hemorrhage in diabetes, also known as diabetic combined retinopathy, is treated according to the stage of diabetic retinopathy in which it is located. In stages I to III of diabetic retinopathy, medications to improve retinal microcirculation, such as calcium hydroxybenzenesulfonate 0.5g orally three times daily for a course of 3 months, can be given. In stage IV of diabetic retinopathy, preferably at the end of stage III to stage IV, total retinal photocoagulation therapy is given. In case of stage IV to V, vitreous accumulation of blood without resorption, proliferation, and traction, vitrectomy treatment with retinal photocoagulation is recommended. If there is obvious macular edema, grating-like photocoagulation can be given to the macular area, and intravitreal injection of rezumab and Compazepine can also be given to quickly eliminate macular edema.
