Bowman's layer in the cornea develops from cytokine-mediated interactions between epithelial cells and keratocytes. This layer may indicate ongoing stromal-epithelial interactions and might not have a critical physiological function.

Area of Science:

  • Ophthalmology
  • Corneal Biology
  • Cellular Interactions

Background:

  • Bowman's layer is a distinct structure within the anterior cornea.
  • Its precise developmental origin and functional significance remain areas of investigation.
  • Understanding Bowman's layer is crucial for comprehending corneal physiology and pathology.

Purpose of the Study:

  • To review existing knowledge on the development, structure, and function of Bowman's layer.
  • To describe disease-related abnormalities affecting Bowman's layer.
  • To propose a novel hypothesis for the development and maintenance of Bowman's layer.

Main Methods:

  • Comprehensive literature review of studies related to Bowman's layer.
  • Formulation of a new hypothesis based on synthesized information from previous research.

Main Results:

  • Evidence suggests Bowman's layer formation is driven by cytokine-mediated interactions between corneal epithelial cells and keratocytes.
  • These interactions involve chemotaxis and apoptosis, influencing keratocyte behavior.
  • The proposed mechanism accounts for Bowman's layer development from early life through adulthood in various species.

Conclusions:

  • Bowman's layer may serve as a visual marker of continuous stromal-epithelial interactions in the human cornea.
  • It might lack a critical role in overall corneal physiological function.
  • Disruption of stromal-epithelial interactions, as seen in bullous keratopathy, can lead to Bowman's layer destruction, while new Bowman's-like layers can form in response to epithelial changes.
