Key Points

  • This research aims to understand how chronic psychological stress affects meibomian gland function through β-adrenergic signaling.
  • Examined the impact of chronic psychological stress on meibomian glands.
  • Assessed changes in circadian regulation and lipid metabolism.
  • Investigated effects of β-adrenergic blockade as a potential treatment.
  • Chronic stress led to disruptions in meibomian gland homeostasis.
  • Altered circadian rhythms and lipid profiles were observed.
  • β-adrenergic blockade showed partial reversal of stress-induced changes.

Abstract

Chronic psychological stress disrupts MG homeostasis through sympathetic overactivation, affecting circadian regulation, immune responses, and lipid metabolism. β-Adrenergic blockade partially reverses these changes, highlighting a potential therapeutic approach for stress-related evaporative dry eye.
