What happens if there is a blood clot in the eye?

Blood clots in the eye are usually caused by burst bleeding of capillaries in the eye. The blood will gather under the conjunctiva and slowly form blood clots later. It is related to chronic diseases such as high blood pressure or diabetes. It can also be caused by trauma or severe coughing.

1. Hypertension: Patients with hypertension will have symptoms of high blood pressure, so the pressure of the flowing blood on the blood vessel wall will continue to increase, which will be higher than the normal value. It is difficult to treat and requires long-term medication. If the blood pressure value is relatively high, it may cause capillary dilation and cause rupture and bleeding.

2. Diabetes: People with diabetes usually have symptoms of high blood sugar levels, and there will be major complications, such as damage to eye tissue, or damage to nerve and blood vessel tissue, resulting in blood vessel rupture and blood clots in the eyes.

3. Trauma: Many people will experience dilation of blood vessels in their eyes and bleeding symptoms after suffering trauma. If not treated in time, it will usually lead to blood clot formation, which will affect the health of the eyes and induce inflammation.

4. Severe coughing: Severe coughing will cause increased abdominal pressure. Severe coughing will cause blood vessels in the eyes to dilate and bleed, and blood will coagulate under the conjunctival hairs.
