Neurotrophic keratitis, a corneal disease, results from nerve damage. This leads to dry eyes and poor healing, potentially causing ulcers and perforation if not treated early.

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Regenerative Medicine

Background:

  • Neurotrophic keratitis is a degenerative corneal condition.
  • It stems from damage to the trigeminal nerve's corneal branches.
  • This damage impairs corneal sensation and healing.

Purpose of the Study:

  • To explain the pathophysiology of neurotrophic keratitis.
  • To highlight the consequences of reduced corneal innervation.
  • To emphasize the importance of early diagnosis and treatment.

Main Methods:

  • Review of existing literature on neurotrophic keratitis.
  • Analysis of the relationship between nerve damage and corneal health.
  • Pathophysiological explanation of disease progression.

Main Results:

  • Reduced corneal innervation disrupts tear film stability.
  • Impaired epithelial healing capacity (mitosis, migration) is a key factor.
  • The combination leads to persistent epithelial defects and potential ulcers.

Conclusions:

  • Neurotrophic keratitis results from trigeminal nerve damage affecting the cornea.
  • Tear film deficiency and impaired healing create a risk for severe complications.
  • Prompt diagnosis and treatment are crucial to prevent corneal ulceration and perforation.
