Summary

This study describes an atypical peripheral corneal opacification in six female patients, presenting with ocular irritation and potential vision changes. The condition, resembling Salzmann nodular degeneration, showed variable progression and response to surgical treatment.

Area of Science:

  • Ophthalmology
  • Corneal Diseases

Background:

  • Peripheral corneal opacities can have various etiologies.
  • Atypical presentations require careful characterization for accurate diagnosis and management.

Observation:

  • A retrospective case series identified six female patients with bilateral, symmetric, peripheral, hypertrophic, subepithelial corneal opacifications.
  • Patients reported ocular irritation, blurred vision, or monocular diplopia.
  • Pathology revealed subepithelial fibrosis without inflammation.

Findings:

  • The corneal opacities were atypical and did not fully align with typical Salzmann nodular degeneration.
  • Progression was observed in two of three patients with over 30 months of follow-up.
  • Surgical intervention with superficial keratectomy and mitomycin-C was performed in two patients.

Implications:

  • This condition represents a distinct clinical entity requiring further investigation.
  • Understanding the natural history and treatment outcomes is crucial for patient care.
  • Differentiating this from other peripheral corneal conditions is essential for appropriate management.
