Vitreous hemorrhage and retinal neovascularization usually require surgery and are among the more serious conditions in ophthalmology. Retinal neovascularization is usually caused by diseases such as diabetic retinopathy and retinal vein embolism, and retinal neovascularization can result in spontaneous leakage and hemorrhage, leading to vitreous hemorrhage. If left untreated, it may eventually develop into detached retina, which can severely damage the patient’s vision and is therefore a more serious eye disease. Treatment is mainly through medication to promote the absorption of vitreous hemorrhage, such as lecithin complexed iodine. If the blood is not absorbed for a long time, patients can have surgery, such as vitrectomy, to remove the vitreous blood. At the same time, patients also need to undergo laser surgery to close the non-perfused area of the retina and make the retinal neovascularization subside. It is recommended that patients with vitreous hemorrhage and retinal neovascularization be seen promptly for evaluation of their condition and treatment as prescribed.
