Typically the fingers, and, less commonly, the toes, are involved. [1] Rarely, the nose, ears, nipples, or lips are affected. [1] The episodes classically result in the affected part turning white and then blue. [2] Often, numbness or pain occurs. [2] As blood flow returns, the area turns red and burns. [2]
There are also a number of other conditions that affect hands, feet, and parts of the face with associated skin color changes that need to be differentiated from acrocyanosis: Raynaud phenomenon, pernio, acrorygosis, erythromelalgia, and blue finger syndrome. The diagnosis may be challenging in some cases, especially when these syndromes co-exist.
Raynaud’s disease is a rare peripheral vascular syndrome that narrows blood vessels, generally in the hands and feet, due to cold or stressful emotion. [8] It is recognized by the reduction of blood flow to fingers and toes with periodic spasm and results in a drastic color change to white or blue.
In these eyes, an elevated pressure in the retinal veins has been observed. [ 10 ] Glaucoma patients with Flammer syndrome show some specific clinical signs like increased frequency of optic disc haemorrhages, activated retinal astrocytes, elevated retinal venous pressure, optic nerve compartmentalization, and fluctuating diffuse visual field ...
What causes pruney fingers? “When our fingers and toes are submerged in water, the sympathetic nervous system triggers the blood vessels in our fingers and toes to constrict, causing skin ...
Peripheral cyanosis is the blue tint in fingers or extremities, due to an inadequate or obstructed circulation. [5] The blood reaching the extremities is not oxygen-rich and when viewed through the skin a combination of factors can lead to the appearance of a blue color .
Blue toe syndrome is a situation that may reflect atherothrombotic (clots resulting from the build-up of fats, cholesterol, and other substances in and on the artery walls) [1] microembolism, causing transient focal ischaemia, a temporary blockage of blood flow to the brain or spinal cord, [2] occasionally with minor apparent tissue loss, but without diffuse forefoot ischemia.
