Often the person does not realize, that a blood vessel has burst, unless he stands in front of a mirror. The sclera (the white part of the eye) turns red, when a blood vessel breaks. When it affects other parts of the body, there is a purplish welt with blood spot appearing on the welt.
When the blood sugar is high, the blood vessels get damaged, causing localized weak areas. Over time, these weak areas start to protrude out, forming a microaneurism. When an aneurism bursts, blood enters into the vitreous, causing a vitreous hemorrhage. Abnormal vessels that grow in response to low oxygen levels in retinal vascular conditions (proliferative diabetic retinopathy, vein occlusions, etc) are very fragile and tend to leak. Sometimes these abnormal vessels grow from the retina into the vitreous cavity and leak blood, causing a vitreous hemorrhage. Mechanical damage to the blood vessels of the retina can occur from a retinal tear or trauma to the eye. Like any other part of the body, if a blood vessel gets damaged, it will start to bleed.
