What Is a Choroidal Nevus?

Choroidal hemorrhage has important clinical significance. No matter how much bleeding is due to its damage to the retina, it can lead to permanent vision impairment, especially bleeding in the macula. Local choroidal hemorrhage is also limited to those in the choroid, showing dark red, nodular or round clumps of varying sizes, with retinal blood vessels passing on the surface, and the retina appearing as a smoke-like gray or white, and the visual field appears at the corresponding place dark spot. If the macular area is affected by bleeding, central vision is significantly reduced. Bleeding is absorbed slowly and generally lasts several months. The remaining permanent scar is slightly smaller than the original bleeding mass, and the remaining choroidal white fibers and irregular pigment blocks can be seen as blind spots in the corresponding position in the visual field.

Common causes

Choroidal neovascularization

Common symptoms

There is a large amount of vitreous overflow, followed by retinal and choroidal detachment, blood is constantly flowing from the eyes, etc.

Causes of choroidal hemorrhage

There are many possible causes of choroidal hemorrhage, of which choroidal neovascularization is an important cause. It is mainly seen in macular degeneration in the elderly and highly myopic macular lesions. Usually the bleeding is near the macular area, causing a sudden decrease in central vision. In addition, choroidal hemorrhage may occur in central exudative choroidal retinopathy, traumatic choroidal rupture, idiopathic polypoid choroidal vascular disease, and systemic diseases such as hypertension, arteriosclerosis, hematopathy, and diabetes. In addition to the above, there is also a severe and massive fulminant hemorrhage called choroidal violent bleeding.

Clinical manifestations of choroidal hemorrhage

If choroidal hemorrhage occurs during the operation, the wound can be seen, the iris and lens are moved forward, the eye contents come out from the wound, the lens comes out by itself, and there is a large amount of vitreous overflow, followed by the retina and the choroid, and finally the red blood continues to come from the eye Gushing out; local anesthesia patients often have restlessness and severe pain, which is a typical manifestation of severe choroidal hemorrhage in patients with large eyeball incision surgery. Mild cases have less or slower bleeding. After the wound was closed, the intraocular pressure increased, the bleeding stopped, and localized hemorrhage in the suprachoroidal space was seen under the fundus microscope.

Choroidal hemorrhage

Laboratory inspection

Carry out laboratory tests related to primary diseases such as diabetes and bleeding disorders, such as blood glucose, bleeding and coagulation indicators.

2. Other auxiliary inspections

The onset of choroidal hemorrhage is sudden. After the condition is stable, ultrasound examination can be considered to determine the retinopathy caused by choroidal hemorrhage.

Choroidal bleeding diagnosis

Diagnosis can be made based on the cause, clinical manifestations, and laboratory tests.

Choroid hemorrhage complications

Eye contents prolapsed and the eyeballs were damaged.

Choroid hemorrhage treatment

Once choroidal hemorrhage occurs, we must first control the bleeding by various methods to achieve the purpose of preserving vision and eyeballs. Generally, measures should be taken to close the wound in time. If the bleeding cannot be prevented, the sclera can be opened 8 to 10 mm behind the limbal limbus to release hemorrhage from the choroid, which can often save the eyeballs.

Choroidal bleeding prevention

In order to prevent choroidal hemorrhage, a comprehensive examination is performed before the operation, including blood vessel fragility and coagulation function tests, to control blood pressure and intraocular pressure; light operation should be performed during surgery to avoid excessive eye content overflow.

1. Pay attention to rest and do not use your eyes excessively.

2. Maintain good habits, get enough sleep, and stay up late. Avoid continuously operating the computer for a long time, pay attention to the rest, usually operate for 1 hour and rest for 5 to 10 minutes. Look at the distance or do eye exercises during breaks.

3. Be careful not to shine directly into your eyes. Also prevents eye trauma. Actively treat the primary disease, so as not to cause choroidal bleeding.

4. Maintain a good working posture. Maintaining the most appropriate posture, with your eyes upright or a slight downward gaze, will ease the neck muscles and minimize the area of the eye exposed to the air.
