Summary

Soft contact lens wearers with corneal irregularities resistant to acyclovir may have Acanthamoeba keratitis. Prompt epithelial debridement resolved the condition, highlighting the importance of contact lens hygiene.

Area of Science:

  • Ophthalmology
  • Microbiology
  • Infectious Diseases

Background:

  • Corneal irregularities unresponsive to antiviral therapy can present diagnostic challenges.
  • Soft contact lens wear is a known risk factor for microbial keratitis.

Observation:

  • Two patients exhibited dendritiform corneal irregularities despite topical acyclovir treatment.
  • Both patients were soft contact lens users with poor lens hygiene practices.

Findings:

  • Acanthamoeba species was identified in corneal biopsies and contact lens samples.
  • Successful resolution of corneal irregularities was achieved through epithelial debridement alone.

Implications:

  • This case series suggests Acanthamoeba keratitis should be considered in contact lens wearers with atypical corneal presentations.
