    Patients with anorexia nervosa (AN) have reduced superficial macular vascular density (VD) compared to controls. Optical coherence tomography angiography (OCTA) may detect these early vascular changes.

    Area of Science:

    • Ophthalmology
    • Cardiovascular Research
    • Nutritional Neuroscience

    Context:

    • Anorexia nervosa (AN) is a complex eating disorder with potential systemic effects.
    • Ocular vascular changes may serve as early indicators of malnutrition-related complications.
    • Optical coherence tomography angiography (OCTA) offers a non-invasive method to assess retinal vasculature.

    Purpose:

    • To compare macular and peripapillary vascular density (VD) in patients with AN versus healthy controls.
    • To evaluate the utility of OCTA in detecting vascular alterations in AN.
    • To investigate potential correlations between malnutrition and ocular blood flow.

    Summary:

    • Optical coherence tomography angiography (OCTA) revealed significantly lower superficial macular vascular density (VD) in patients with anorexia nervosa (AN) compared to age-matched healthy controls.
    Keywords:
    anorexia nervosa - OCTA - optical coherence tomography angiography - microcirculation - anaemia

  • No significant differences in deep macular or radial peripapillary capillary (RPC) VD were observed between groups.
  • These findings suggest malnutrition in AN may lead to reduced superficial macular blood supply.

    • Impact:

    • Reduced superficial macular VD in AN may be a consequence of malnutrition.
    • OCTA shows promise as a non-invasive tool for identifying reduced peripheral blood supply and early vascular changes in AN.
    • This research highlights potential ocular manifestations of AN, aiding in early detection and management.
