summary

This disease may be a non-specific inflammatory reaction of the anterior choroidal capillaries to different causes, and may be a part of the systemic vascular reaction. Patients with acute choroidal ischemia often go to see a doctor because of vision loss or even blindness. With the wide application of fundus fluorescein angiography and the gradual popularization and application of indocyanine green angiography, the understanding of choroidal vascular diseases is being further studied. Immediate symptoms of choroidal ischemia? Let's talk about it

Immediate symptoms of choroidal ischemia?

Patients with acute choroidal ischemia often go to see a doctor because of vision loss or even blindness. The fundus appearance depends on the size and number of occluded vessels and the stage of the disease. Fresh lesions are in the supply area of the blocked vascular branches,

The outer layer of retina and subretina showed gray edema. If one of the main branches of the posterior ciliary artery (temporal or nasal posterior ciliary artery) is blocked, edema and turbidity will appear in the fundus of the side supplied by it. If the two branches are blocked, the whole fundus is gray edema.

Local choroidal obstruction occurs due to the occlusion of the terminal choroidal arterioles supplying a single choroidal capillary lobule. It can be seen in all kinds of systemic diseases mentioned above. The onset of this disease is acute, and the visual acuity drops sharply. It usually occurs in young adults, usually in both eyes, but also in one eye. In the acute stage, most scattered small yellow and white round spots can be seen in the posterior pole of the fundus, with unclear boundary and different sizes. Sometimes, fusion lesions can be seen, showing flake or even map shape.

matters needing attention

Appropriate diet: 1. It is suitable to eat food with anti-inflammatory effect; 2. Food with anti infective effect should be eaten; 3. It is advisable to eat food that can improve immune function; 4. It is advisable to eat food with diuretic effect.
