title: Near-infrared spectrophotoscopy of finger venules in assessment of autonomic dysfunction.
abstract: The authors evaluated morphologic changes in the venules of the finger using near-infrared spectrophotoscopy in patients with autonomic dysfunction, such as familial amyloidotic polyneuropathy and multiple-system atrophy. Abnormalities of the venules, such as tortuosity, irregular venous caliber, and microaneurysm-like change, and a linear negative correlation between the degree of orthostatic hypotension and the degree of vasoconstriction of the venules were observed.
