causes of broken capillaries eyes
Some of these involves the presence of blood clots that obstruct the blood flow in the veins, the inflammation of the veins or phlebitis, and liver damage. Conditions like tumors or constipation that results to increased pressure in the abdomen can cause broken capillaries, too.
Vigorous coughing is one possible reason for burst eye capillaries. When a capillary in the white part of the eye bursts -- called a subconjunctival hemorrhage -- the appearance of blood can be rather dramatic and alarming. Often, there is no history of trauma to the eye -- the blood simply appears spontaneously.
