To determine whether vitreous hemorrhage is absorbed or not, the first thing to do is to look at the change of visual acuity and the ultrasound examination of the eye. Vitreous hemorrhage mainly affects the vision and causes the intraocular pressure to rise. There are many reasons for vitreous hemorrhage, such as eye trauma, eye disease, systemic disease can cause hemorrhage, usually after medication, laser surgery can be slowly absorbed. After absorption, vision is restored, and ultrasound examination of the eye shows that the vitreous humor is reduced or completely absorbed. Vitreous hemorrhage can be caused by a variety of reasons, usually through oral hemostatic drugs, laser treatment or surgery, can promote absorption. If there are systemic diseases, active treatment of systemic diseases, such as hypertension, diabetes mellitus, blood diseases, etc., should also be carried out. When the occurrence of vitreous hemorrhage caused by vision changes, should promptly go to the hospital, under the guidance of the physician, to clarify the cause and give targeted treatment.
