Red blood level below the anterior chamber

Introduction A red blood level below the anterior chamber is a symptom description of anterior chamber hemorrhage. After eyeball damage, the vascular permeability of the iris increases or due to rupture of the blood vessel, and blood accumulates in the anterior chamber called traumatic anterior chamber. A small amount of anterior chamber blood does not cause serious damage, but its complications and accompanying lesions can have serious consequences for visual function. Hemorrhagic-related glaucoma includes anterior chamber blood-seeding glaucoma, hemolytic glaucoma, and hemorrhagic glaucoma, with pre-hospital blood being the most common. Other rare spontaneous anterior chamber blood includes intraocular tumors, neovascular glaucoma, ocular cholesterol, and sickle cell disease.

Cause

Eye contusion is an important cause of anterior chamber hemorrhage. The wounds include slingshots, throws, balls, and elbow injuries. Internal eye surgery combined with anterior chamber blood with the popularity of microsurgery, improved surgical skills, the incidence of intraocular hemorrhage in intraocular surgery is getting lower and lower. Spontaneous anterior hemorrhage is less common and can be caused by the following causes: intraocular tumor, iris reddenation, fibrous vascular membrane bleeding in the posterior or suspensory ligament region, and drugs.

(5) Blacks and Mediterraneaners: Sickle cell or sickle cell anemia should be examined.

2. Spontaneous anterior chamber hemorrhage, postoperative anterior chamber hemorrhage or anterior chamber micro-hemorrhage; add the following examination on the basis of traumatic anterior chamber hemorrhage:

(1) Corner mirror inspection.

(2) Spontaneous bleeding should consider the following tests: 1 prothrombin time, partial kinase time, whole blood count plus platelet count, protein C and S protein. 2 iris fluorescein angiography. 3 Ultrasound biological microscope to observe the position of the artificial lens and the iris.

Differential diagnosis

Diagnosis can be performed based on clinical manifestations.

When there is more bleeding, the volume of blood accumulated in the anterior chamber can be divided into 3 levels: less than 1/3 is grade I; 1/3 to 2/3 is grade II; more than 2/3 is grade III. Or record the actual height of the blood level (in millimeters). In severe cases, the anterior chamber is completely filled with blood and can be black. The anterior chamber blood can absorb itself. However, when the amount of blood is large, or bleeding during absorption, it can cause secondary glaucoma. Corneal endothelium damage, high intraocular pressure and hemorrhage can cause corneal blood staining. The corneal stroma is brownish yellow, and the center is disk-like turbid. Later, it turns yellow-white and does not fade for a long time.
