Introduction
Sudden eye bleeding may be caused by eye strain, excessive eye rubbing, conjunctivitis, eye injury, high blood pressure, or other reasons. To protect eye health, it is important to avoid prolonged eye use, refrain from excessive eye rubbing, maintain good eye hygiene, take precautions against eye injuries, and regularly monitor blood pressure to prevent eye problems caused by hypertension.
Under normal circumstances, sudden eye bleeding may be caused by factors such as eye strain, excessive eye rubbing, conjunctivitis, ocular trauma, or high blood pressure. If any of these conditions occur, prompt medical attention is recommended. Specific analyses are as follows:
1. Eye strain
Prolonged focus on electronic screens such as computers and smartphones, or reading books, can lead to eye fatigue and conjunctival congestion, potentially resulting in sudden eye bleeding. No special treatment is required; instead, take regular breaks by looking into the distance or closing the eyes to rest.
2. Excessive eye rubbing
When experiencing eye discomfort, people often habitually rub their eyes. However, if the rubbing is too forceful or performed improperly, it may damage the conjunctiva. The capillaries beneath the conjunctiva may rupture due to external pressure, leading to eye bleeding. Avoid excessive eye rubbing. If discomfort occurs, rinse the eyes with saline solution to relieve symptoms.
3. Conjunctivitis
Caused by infections from viruses, bacteria, or other microorganisms, conjunctivitis leads to inflammation of the conjunctiva. Inflammatory factors can cause dilation and rupture of capillaries beneath the conjunctiva, resulting in sudden eye bleeding, often accompanied by redness and pain. Follow a doctor's advice to use medications such as levofloxacin eye drops, olopatadine hydrochloride eye drops, or acyclovir eye drops for treatment.
4. Ocular trauma
Physical impact or accidental injury from sharp objects can damage ocular tissues and cause rupture of blood vessels in the eye, leading to sudden bleeding. This is often accompanied by symptoms such as eye pain and swelling. Under medical guidance, treatments may include tobramycin eye drops, chloramphenicol eye drops, or ibuprofen sustained-release capsules.
5. High blood pressure
Long-term uncontrolled hypertension can cause spasm and hardening of small arteries in the retina. In severe cases, vitreous hemorrhage may occur, damaging retinal blood vessels, thinning vessel walls, and making them prone to rupture and bleeding, thus causing sudden eye bleeding. This may be accompanied by dizziness and headaches. Follow medical instructions to use medications such as timolol maleate eye drops, nifedipine sustained-release tablets, or irbesartan tablets for treatment.
To prevent eye problems—especially those related to hypertension—it is important to avoid prolonged eye use, refrain from excessive eye rubbing, maintain good eye hygiene, take precautions against eye injuries, monitor blood pressure regularly, and keep blood pressure stable.
