Microangiopathies are a group of disorders characterized by damage to small blood vessels, particularly capillaries, arterioles, and venules. This damage can lead to various complications, including reduced blood flow and tissue ischemia. Common conditions associated with microangiopathies include diabetes mellitus, hypertension, and systemic lupus erythematosus. The effects of microangiopathies can manifest in multiple organs, such as the kidneys, eyes, and nervous system. For instance, diabetic retinopathy is a type of microangiopathy that affects the eyes, potentially leading to vision loss. Early detection and management are crucial to prevent severe complications and improve patient outcomes.
