Summary

A rare horseshoe-shaped linear epithelial keratitis case was treated with deep corneal scraping. This intervention led to healing without recurrence, suggesting a novel therapeutic approach for resistant cases.

Area of Science:

  • Ophthalmology
  • Corneal Diseases
  • Microbiology

Background:

  • Linear epithelial keratitis with a horseshoe pattern is a rare corneal condition.
  • This specific pattern often presents diagnostic challenges and can be resistant to standard treatments.

Observation:

  • A 21-year-old soldier presented with horseshoe-shaped epithelial keratitis unresponsive to immunosuppressants and antimicrobials.
  • Diagnostic tests, including cultures and PCR for herpes simplex virus, were negative for microorganisms.
  • Impression cytology showed polymorphonuclear leukocyte infiltration.

Findings:

  • The keratitis did not respond to various antimicrobial therapies or corticosteroids.
  • Deep corneal scraping using a disc-knife resulted in complete lesion healing.

  • The condition remained resolved without recurrence for six months post-treatment.

    • Implications:

    • Deep corneal scraping may be an effective treatment for recalcitrant linear epithelial keratitis with a horseshoe pattern.
    • This case suggests that such keratitis may not always be associated with infectious agents or systemic diseases.
    • Further research into the etiology and optimal management of this specific corneal presentation is warranted.
