What causes red eyes?

Redness inside the eyes is quite common in life, and the specific symptoms caused are also different. The more common ones are some infectious diseases of the eyes. The most common is acute conjunctivitis, which often causes patients to suffer from photophobia, constant tears, etc. Some other diseases may also be prone to this phenomenon, such as heart failure, arteriosclerosis, acute congestive glaucoma, etc.

What causes red eyes? 1. Eye infections, such as acute conjunctivitis. In addition to red eyes, there are also secretions. Vision is generally not affected, or things are slightly blurred. If inflammation occurs in the cornea, iris, ciliary body or intraocular tissue, redness of the eyes may occur suddenly, accompanied by irritation symptoms such as photophobia and tearing, and vision may also be affected. In addition, inflammation of the eyelid skin near the eyeball, styes (commonly known as stye) or orbital infection can all cause red eyes.

2. When acute congestive glaucoma occurs, red eyes may occur due to impaired intraocular fluid circulation, increased intraocular pressure, and congestion of blood vessels.

3. When systemic or local circulation is blocked due to heart failure, orbital tumors, intracranial cavernous sinus thrombosis, etc., red eyes will appear due to congestion of blood vessels in the eyes.

4. The ocular blood vessels of patients with arteriosclerosis may be damaged, resulting in subconjunctival hemorrhage, causing red eyes.

5. When the eyes are allergic to drugs or chemicals, or are damaged, the blood vessels may become congested, bruised or ruptured, causing them to become red. 6. In addition to eye bleeding, blood diseases also cause bleeding in other parts of the body, such as hemoptysis, nosebleeds, menorrhagia, skin hemorrhages, etc. 7. Pterygium is a triangular fleshy tissue that grows on the white of the eyeball (sclera). Because there are many blood vessels on it, when it grows rapidly, it can make the eyeball appear red. If red eyes occur, the cause should be found and treated accordingly.
