This review details human corneal nerve structure and function, highlighting neurochemicals and neurotrophins. It discusses their role in corneal health, healing, and treating neurotrophic keratitis using in vivo confocal microscopy (IVCM).

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Cell Biology

Background:

  • Corneal nerves are crucial for maintaining ocular surface homeostasis and function.
  • Understanding corneal nerve structure and neurochemical signaling is vital for diagnosing and treating corneal diseases.
  • Recent advancements in imaging and molecular techniques offer new insights into corneal innervation.

Purpose of the Study:

  • To provide a comprehensive review of human corneal nerve structure, neurochemical content, and functions.
  • To present a revised interpretation of corneal nerve architecture based on novel imaging and analytical methods.
  • To discuss the therapeutic potential of neurochemicals and neurotrophins in managing corneal conditions, particularly neurotrophic keratitis.

Main Methods:

  • In vivo confocal microscopy (IVCM) for real-time imaging of corneal nerves.

  • Immunohistochemistry to identify specific neurochemical markers within corneal nerves.
  • Ultrastructural analysis of serial-sectioned human corneas for detailed architectural examination.

    • Main Results:

    • A revised model of human corneal nerve architecture is proposed.
    • Corneal nerves contain a variety of neurotransmitters and neuropeptides that influence corneal physiology.
    • Neurotrophins play a significant role in corneal homeostasis and wound healing processes.

    Conclusions:

    • Corneal neurochemicals and neurotrophins are key regulators of corneal health and repair.
    • Topical application of neuropeptides and neurotrophins shows promise for treating neurotrophic keratitis.
    • IVCM is a valuable tool for assessing corneal nerve status in both healthy and diseased corneas.
