Vitreous hemorrhage

Hemorrhage of vitreous body is a common complication of eye damage caused by ocular trauma or retinal vascular disease. On the one hand, hemorrhage not only makes the refractive medium turbid and prevents the light from reaching the retina, but also can cause serious damage to the eye tissues; on the other hand, the body's response to the bleeding can gradually clear the blood. In different cases, the consequences of vitreous hemorrhage are very different. It should be given appropriate clinical treatment in a timely manner according to the primary injury, the amount of bleeding in the office, the absorption of bleeding, and the performance of the eye reaction. When blood vessels around the vitreous body, such as the retina and uveal membrane, rupture, blood flows in and accumulates in the vitreous body. Retinal vascular disease, blood disease, intraocular tumors, retinal holes and trauma can all cause. When the amount of bleeding is small, it is manifested as flying mosquito. When the amount is large, it is red vision, and a large amount of vitreous hemorrhage seriously affects vision. A small amount of vitreous hemorrhage is easily absorbed, the vitreous body can be restored to be transparent, and a large amount of bleeding is difficult to absorb. If repeated bleeding occurs, a dense film is formed. This film can be contracted and traction can cause secondary retinal detachment. Therefore, vitreous hemorrhage should be identified as soon as possible and treated early. It is mainly aimed at treating the primary disease. When there is fresh bleeding, the patient should rest in bed and take a hemostatic medicine to prevent rebleeding. When the amount of bleeding is high and the intraocular pressure is high, secondary glaucoma needs to be controlled. Use various methods to promote early absorption of intravitreal hemorrhage. Hyaluronidase is commonly used
