A red plane of blood below the anterior chamber is a symptom description of anterior chamber hemorrhage. After an eye injury, increased permeability of the iris vessels or accumulation of blood in the anterior chamber due to ruptured vessels bleeding is called traumatic anterior chamber hemorrhage. Small amounts of anterior chamber hemorrhage do not cause serious damage, but the complications and accompanying lesions in large amounts of hemorrhage can have serious consequences for visual function. Hemorrhagic glaucoma includes anterior chamber hemophakic glaucoma, hemolytic glaucoma and hematocrit glaucoma, of which anterior chamber hemorrhage is the most common. Other rare spontaneous anterior chamber hemorrhages include intraocular tumors, neovascular glaucoma, ocular cholesterolosis, and sickle cell disease. What is the prevention of red blood planes below the anterior chamber? 1, the disease should be bed rest, bandage the affected eye to prevent rebleeding. 2, such as blood irrigation pupillary external obstruction, should be semi-horizontal rest, so that the stagnant blood sinks, in order to avoid blood obscuring the pupil, affecting vision. 3, eat more food to stop the blood and brighten the eyes, avoid taking tobacco, alcohol, five pungent and other dry fire products, forbidden to eat male chicken, fish, eggs and other hair products. 4, early to bed and early to rise, exercise the body. Lack of sleep will reduce the body’s immune function, but also easy to excite the fire, resulting in external internal injuries. 5, keep a calm state of mind. Spring avoid anger, do not be too impatient to deal with things, to keep a calm state of mind from time to time. 6, quit smoking, less alcohol and coffee.
