Extravascular Motion Signal Detected by OCT Angiography Indicates Altered Vascular-Tissue Biomechanical Interactions in Glaucoma

Key Points

• To explore the relationship between extravascular motion signals and vascular-tissue interactions in glaucoma.
• Utilized OCT angiography to measure extravascular motion signals.
• Investigated signals adjacent to arteries, particularly in eyes with early glaucoma (EG).
• Analyzed influences of intraocular pressure (IOP) on tissue displacement.
• EVM signals were more prominent in early glaucoma eyes compared to controls.
• Signals correlated strongly with variations in intraocular pressure.
• Findings suggest altered biomechanical properties in ocular tissues.
