5 Key Takeaways

• 1

  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.
