Repeated rupture of capillaries on the surface of the eye may be due to physical injury, intraocular vibration, systemic diseases, etc. The walls of capillaries on the surface of the eye are relatively fragile, and many factors can lead to rupture. 1. Physical injury: If the eyeball is traumatized by the outside world, it will also cause rupture of the blood vessels on the surface of the eye, usually the eye will also show redness, swelling, pain, and some patients will also have blood spots on the conjunctiva. 2. Intraocular vibration: some patients sneeze and cough too violently, resulting in intraocular vibration, which may cause the surface capillaries to rupture and bleed. 3. Systemic diseases: some patients have high blood pressure, diabetes affects the fragility of blood vessels, which may also cause the rupture of capillaries on the eye surface. In addition, some thrombocytopenia, due to the body’s platelet reduction, can also trigger the above situation. When the eye surface capillary rupture, we should go to the regular hospital in time to avoid serious consequences.
