Introduction
Introduction to anterior chamber blood 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. Traumatic anterior chamber hemorrhage is more common in eyeball contusion, which is a common complication. Domestic statistics account for 11.3% of outpatient eyeball contusions and 39.8% of inpatients. Lighter ones can heal themselves, most of them can be completed in about 6 days. Absorption, visual recovery, but a large number of bleeding or repeated secondary anterior chamber blood, secondary glaucoma and corneal blood stains can cause blindness. basic knowledge Sickness ratio: 0.05% Susceptible people: no specific population Mode of infection: non-infectious Complications: glaucoma glaucoma
Cause
Anterior chamber hemorrhagic disease
1. Traumatic eye wall hemorrhage: After eyeball damage, the vascular permeability of the iris increases or the blood vessels rupture due to rupture of blood vessels, and blood accumulates in the anterior chamber.
2. Spontaneous bleeding: occult trauma must be ruled out
(1) New blood vessels in the iris or corner.
(2) cachexia.
(3) Iris-arthritis.
(4) Others such as iris microaneurysm, leukemia, retinoblastoma, etc.
Prevention
Anterior chamber blood prevention
1. It is advisable to stay in bed and wrap the affected eye to prevent further bleeding.
2. If the blood is sputum, the distress should be kept in a semi-recumbent manner to make the blood stagnant, so as to prevent the blood from covering the gods and affecting vision.
3. Eat more food to stop bleeding and eyesight, avoid smoking and drinking Wuxin and other dry fire products, fasting roosters, fish, eggs and other hair.
4. Go to bed early and get up early and exercise. Insufficient sleep can reduce the body's immune function, and it is also easy to stimulate the fire, causing external injuries.
5. Keep your mind calm. Avoid anger in the spring, do not be too impatient, always keep your peace of mind.
6. Quit smoking, drink less and drink coffee. Smoking is the most vulnerable to damage to the respiratory surface barrier and induces disease onset. Tobacco, alcohol and coffee all stimulate nervous excitement. Some people want to "eliminate tension and fatigue", but actually weaken the body's disease resistance.
Complication
Anterior chamber hemorrhage Complications glaucoma glaucoma
Glaucoma refers to an eye disease in which intraocular pressure is intermittent or continuously elevated. Continuous high intraocular pressure can cause damage to various tissues and visual functions of the eye. If not treated in time, the visual field can be completely lost to blindness.
Symptom
Symptoms of anterior chamber hemorrhage Common symptoms There is a red blood plane pseudo anterior chamber empyema at the base of the anterior chamber.
1. History of trauma.
2. Vision loss.
3, there is a red blood plane below the anterior chamber, less than 1/3 of the anterior chamber blood is a level, blood count up to 1/3--2/3 for the second grade, more than 2/3 for the third grade.
4, more bleeding, increased intraocular pressure, and even with corneal blood.
Examine
Examination of anterior chamber hemorrhage
Traumatic anterior chamber blood:
1. Medical history.
2. Comprehensive eye examination.
3. Image examination If necessary, eyelid and brain CT examination.
4. Blacks and Mediterraneaners should be examined for sickle cell or sickle cell disease.
Spontaneous anterior chamber hemorrhage, postoperative anterior chamber hemorrhage or anterior chamber micro-hemorrhage: Add the following examination based on traumatic anterior hemorrhage:
1. Corner mirror inspection.
2. Spontaneous hemorrhage, the following tests should be considered: (1) prothrombin time, partial kinase time, whole blood count plus platelet count, protein C and S protein, (2) iris angiography, (3) ultrasound biomicroscopy Observe the position of the artifact and the iris.
Diagnosis
Diagnosis of anterior chamber hemorrhage
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 hemorrhages include intraocular tumors, neovascular glaucoma, ocular cholesterol, and sickle cell disease.
