Evaluation of Microcirculation at the Optic Nerve Head in Eyes With Keratoconus

Key Points

• The study aims to evaluate changes in microcirculation at the optic nerve head in keratoconus eyes compared to normal and highly myopic eyes.
• Utilized Laser Speckle Flowgraphy (LSFG) to assess microcirculation.
• Compared microcirculation metrics between keratoconus, normal, and highly myopic eyes.
• Analyzed MBR (mean blur rate) and ARBS (autoregulatory blood supply) values at the optic nerve head.
• Keratoconus eyes exhibited significantly reduced mean blur rate (MBR) at the optic nerve head compared to normal eyes.
• Alterations in autoregulatory blood supply (ARBS) were also observed in keratoconus eyes.
• Findings indicate the need for monitoring optic nerve function in keratoconus.
