Choroidal laceration

Introduction to choroidal laceration The choroid is between the retina and the sclera and is rich in blood vessels and pigment cells. The tolerance to external impact is worse than that of the retina. When the eyeball is transmitted by the external force from the front to the posterior pole, the hard sclera is It is also resistant to the outside, causing rupture and bleeding in the choroid. The extent to which vision is affected varies depending on the location of the rupture. If the rupture is located in or around the macula, it can seriously damage the central vision. There is no special treatment for choroidal rupture. Generally, laceration is not in the center of the macula. Through comprehensive treatment with traditional Chinese and Western medicine, most patients can achieve different degrees of visual acuity recovery, and a few are expected to return to normal. Do not think that choroidal rupture does not require special treatment and delays early. Treatment, affecting the recovery of vision, should also note that choroidal rupture sometimes occurs simultaneously with retinal tears, which must be taken seriously. basic knowledge The proportion of illness: 0.02% Susceptible people: no special people Mode of infection: non-infectious Complications: choroidal hemorrhage, choroidal detachment

Cause of choroidal laceration

When the eyeball is transmitted from the vitreous body to the posterior pole through the impact of the external force from the front, the hard sclera has a resistance on the outside, causing the choroid to rupture and hemorrhage under the action of both internal and external nucleus.

Choroidal laceration prevention

There is no special treatment for choroidal rupture. Generally, laceration is not in the center of the macula. Through comprehensive treatment with traditional Chinese and Western medicine, most patients can achieve different degrees of visual acuity recovery, and a few are expected to return to normal. Do not think that choroidal rupture does not require special treatment and delays early. Treatment, affecting the recovery of vision, should also note that choroidal rupture sometimes occurs simultaneously with retinal tears, which must be taken seriously.

Choroidal laceration complications Complications, choroidal hemorrhage, choroidal detachment

In the advanced stage, choroidal neovascular membrane and traumatic optic neuropathy may occur.

Symptoms of choroidal laceration Common symptoms Visual acuity often hazy blurry visual impairment visual field vision changes retinal edema

1. There is a black shadow in front of the eyes, and the vision is reduced;

2, eye and bottom examination: the bottom of the fundus can be seen in the pale yellow crescent-shaped fissure, concave facing the optic papilla, retinal blood vessels across the local choroid and retinal edema, and bleeding, late in the crack visible pigmentation; serious The choroidal blood vessels rupture and the bleeding can enter the vitreous through the retina.

Examination of choroidal laceration

1. Comprehensive eye examination: including dilated eye examination to exclude retinal tears, check the external and degree of choroidal laceration.

2. Fundus fluorescein angiography: can confirm the location of advanced choroidal neovascular membrane.

Diagnosis and diagnosis of choroidal laceration

diagnosis:

1. The eye has a direct blunt blow history;

2, there are black shadows in front of the eyes, vision loss;

3, fundus examination, the bottom of the fundus can be seen pale yellow crescent-shaped cracks, concave facing the optic nerve nipple, retinal blood vessels across it, local choroid and retinal edema, and bleeding, late visible pigmentation, severe cases, choroidal rupture Bleeding can enter the vitreous through the retina;

4. Fundus fluorescein angiography shows choroidal laceration;

5. There is a corresponding dark spot in the visual field examination.

Differential diagnosis:

1. Guandu myopia eye paint crack.

2. Vascular-like streaks.
