Eyeballs suddenly become bloodshot

The whites of a normal person's eyes are white, but if there are bloodshot eyes, it is probably caused by insufficient rest and sleep. When people are emotionally excited, their eyeballs may become congested, but for some people, their eyeballs suddenly become congested without any warning. The sudden bloodshot eyeball is likely due to some eye disease caused by bacterial infection. So what are the causes of the sudden bloodshot eyeball?

1. What is the cause of sudden bloodshot eyeballs?

1. Acute conjunctivitis

Cause: It is a common epidemic eye disease caused by bacterial and viral infection and is highly contagious. Symptoms: Acute onset, both eyes affected simultaneously or successively, the affected eye has stinging, itching, foreign body sensation, severe cases have photophobia and burning sensation, vision is generally not affected.

2. Keratitis

Cause: Most keratitis is caused by external infection. Minor corneal trauma is often a trigger for infection. Common pathogens are bacteria, fungi, viruses, etc. In addition, corneal immune dysfunction or malnutrition can cause keratitis. Physical symptoms: pain in the affected eye, foreign body sensation, blepharospasm, photophobia, tearing, sudden decrease in vision, etc.

3. Acute angle-closure glaucoma

Cause: The cause of the disease is relatively complex. The incidence rate in women is 2 to 4 times that in men. It mostly occurs in middle-aged and elderly women. It is a binocular disease and has a certain relationship with genetics. It is mainly caused by the closure of the eye's chamber angle, obstruction of the aqueous humor outflow pathway, and increased intraocular pressure. Symptoms: sudden decrease in vision, severe eye pain, ipsilateral migraine, and nausea and vomiting (easily misdiagnosed as gastrointestinal disease).

4. Acute iridocyclitis

Cause: The causes of iris and ciliary body diseases are very complex, and most of them are unknown. They may be related to autoimmune diseases such as rheumatism, tuberculosis, syphilis, viral infections, etc. Symptoms: decreased vision accompanied by obvious photophobia, tearing, and pain, which may radiate to the eyebrow arches, temporal region, and forehead.

2. What to do if your eyeball suddenly becomes bloodshot?

1. Apply to reduce eye congestion

When bleeding occurs in our eyes, we can apply cold compresses to the eyes for the first two days to shrink the dilated blood vessels in the eyes. On the third day, we can switch to hot compresses to promote the dispersion of excess blood stasis. When applying the towel, do not apply cold or hot compress at once. Put the towel on your eyes little by little to give your eyes an adaptation period to prevent the blood vessels in the eyes from suddenly contracting and dilating and bursting.

2. Take appropriate medications

In addition to the above measures, we must take medication. Although mild eye bleeding can recover on its own in three to five days, in order to prevent the condition from worsening and get better faster, we should also take appropriate medications and eye drops under the correct guidance of a doctor. This is good for our health.
