What causes bleeding in the eye?

Under normal circumstances, eye bleeding may be caused by trauma, conjunctivitis, keratitis, uveitis, hypertension, or other reasons. Patients should promptly visit a正规 hospital to determine the underlying cause and receive appropriate treatment accordingly. Specific analyses are as follows:

1. Trauma

When the eye suffers external impact or injury, capillaries under the conjunctiva may rupture, leading to eye bleeding. Symptoms can be relieved initially with cold compresses; after 48 hours, warm compresses may help improve recovery.

2. Conjunctivitis

Conjunctivitis is an inflammatory condition of the conjunctival tissue, which may be caused by bacteria, viruses, allergens, etc. When the conjunctiva becomes inflamed, it stimulates blood vessels in the conjunctiva, causing vessel dilation and congestion, and sometimes resulting in eye bleeding. Patients may take medications such as levofloxacin hydrochloride tablets, acyclovir tablets, or loratadine tablets under medical guidance.

3. Keratitis

Keratitis is an inflammation of the corneal tissue, commonly caused by infections from bacteria, viruses, or fungi, and may also be associated with autoimmune diseases or spread of inflammation from adjacent tissues. Corneal inflammation stimulates nerve endings, causing symptoms such as eye pain, photophobia, and tearing. In severe cases, eye bleeding may occur. Patients may use tobramycin eye drops, ofloxacin eye drops, amoxicillin capsules, or similar medications under a doctor's supervision.

4. Uveitis

Uveitis refers to inflammation of the uveal tract, including the iris, ciliary body, and choroid, which may result from autoimmune disorders, pathogen infections, trauma, or other factors. The inflammation can stimulate uveal blood vessels, leading to vessel dilation and congestion, and occasionally causing eye bleeding. It is recommended that patients use medications such as prednisone acetate tablets, methylprednisolone tablets, or fluorometholone eye drops under medical supervision.

5. Hypertension

Hypertension is a systemic disease. Long-term high blood pressure may lead to retinal vascular abnormalities, including retinal vessel occlusion, retinal vein thrombosis, and retinal vessel rupture. These conditions can all cause eye bleeding, manifesting as subconjunctival hemorrhage or retinal hemorrhage. Patients may take medications such as valsartan/hydrochlorothiazide tablets, nifedipine tablets, or spironolactone tablets as directed by a physician.

In daily life, individuals should wash hands frequently, avoid rubbing their eyes, and wear protective goggles in dusty or smoky environments to prevent bacterial infection of the eyes. If discomfort occurs, prompt medical attention is advised.
