    Retinal blood-flow autoregulation may indicate early glaucoma before structural damage or vision loss is detectable.

  • 2

    Impaired autoregulation was observed in patients with mild primary open-angle glaucoma compared to healthy controls.

  • 3

    The study utilized laser speckle contrast imaging to assess blood flow at the optic nerve head in different patient groups.

  • 4

    Dynamic assessment of vascular reactivity could serve as an early biomarker for glaucoma, supplementing traditional monitoring.

  • 5

    Findings suggest that altered autoregulation may appear before measurable visual field damage in glaucoma suspects.
