Association Between Autonomic Dysfunction and Choroidal Vascularity Index in Fibromyalgia

NCT07345546 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 80

Last updated 2026-04-08

No results posted yet for this study

Summary

Fibromyalgia is frequently accompanied by autonomic nervous system dysfunction, often characterized by sympathetic predominance. Alterations in ocular microcirculation have been reported in the presence of autonomic dysfunction, including potential reductions in choroidal vascular parameters. This observational study aims to examine the association between autonomic symptom burden and the choroidal vascularity index (CVI), a quantitative marker of choroidal vascular structure derived from optical coherence tomography (OCT), in individuals with fibromyalgia compared with age- and sex-matched healthy controls.
