There is a red blood clot next to the eyeball.

A red blood spot next to the eyeball may be caused by physiological factors, or by pathological conditions such as trauma or acute conjunctivitis. It is recommended to treat based on the underlying cause.

I. Physiological Factors

Prolonged use of electronic devices or staying up late can lead to eye fatigue, causing conjunctival congestion. Frequent eye rubbing may then result in rupture of the conjunctival capillaries, leading to blood accumulation under the conjunctiva. Symptoms usually improve with adequate rest or warm compresses to promote ocular blood circulation.

II. Pathological Factors

1. Trauma

The capillaries beneath the conjunctiva are fragile. When the eye suffers external impact, capillaries on the surface of the bulbar conjunctiva may rupture and bleed. It is recommended to seek medical care and, under a doctor's guidance, use medications such as levofloxacin eye drops, vitamin K tablets, and diclofenac sodium sustained-release tablets for anti-inflammatory and pain-relief treatment.

2. Acute Conjunctivitis

When the conjunctiva is infected by pathogens such as viruses or bacteria, an inflammatory response occurs, which, under inflammatory stimulation, may lead to such symptoms. It is recommended to use, under medical supervision, topical anti-infective agents such as levofloxacin eye drops, acyclovir eye drops, or erythromycin eye ointment.

In addition, conditions such as acute iridocyclitis may also cause similar symptoms. It is advisable to visit a hospital to determine the exact cause and receive appropriate treatment.
