Summary

Pellucid marginal degeneration (PMD) is typically bilateral, but this case study details a rare instance of unilateral PMD. This finding expands the understanding of PMD presentation.

Area of Science:

  • Ophthalmology
  • Corneal Diseases

Background:

  • Pellucid marginal degeneration (PMD) is a rare, progressive corneal thinning disorder.
  • It typically affects both eyes (bilateral) and is characterized by inferior peripheral corneal ectasia.

Observation:

  • This report presents a unique case of a patient diagnosed with typical Pellucid marginal degeneration.
  • The patient exhibited a unilateral presentation, affecting only one eye.

Findings:

  • The case confirms that Pellucid marginal degeneration can manifest unilaterally, deviating from its usual bilateral pattern.
  • Diagnostic criteria for PMD were met despite the unilateral presentation.

Implications:

  • This case broadens the clinical spectrum of Pellucid marginal degeneration.
