What's wrong with red eyes

The eyes are indeed easily affected by some diseases, especially some infectious diseases, which are harmful to the health of the eyes. Common symptoms include acute conjunctivitis or conjunctivitis, and some blood diseases can also cause these eye discomfort symptoms.

1. Infectious eye diseases, such as acute conjunctivitis, are common. In addition to red eyes, there is also secretion. Vision is generally not affected, or vision is 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.
