10. Conditions Involving Capillaries
Capillary malformation is a condition in which blood is able to flow through the capillaries more so than normal. This can lead to a number of symptoms, including red dots on the skin.
When it affects the brain, seizures and headaches can occur. Some people will be born with a type of birth mark known as a port wine stain. This is caused by dilated capillaries and is harmless, other than affecting the patients physical appearance. Another condition is macular degeneration, and this is caused by damage to the capillaries in the retina. It is a potentially serious condition and one of the leading causes of blindness.
