This study presents a superficial corneal dystrophy with subepithelial lesions. Superficial keratectomy treatment yielded good visual results without lamellar grafting, suggesting a new classification for granular dystrophy.

Area of Science:

  • Ophthalmology
  • Corneal Diseases
  • Histopathology

Background:

  • Superficial corneal dystrophies present unique clinical and pathological characteristics.
  • Understanding Bowman's layer involvement is crucial for diagnosing and treating corneal dystrophies.
  • Distinguishing between different types of granular dystrophy aids in patient management.

Purpose of the Study:

  • To present seventeen cases of a distinct superficial corneal dystrophy.
  • To analyze the pathological similarities and clinical differences with classic granular dystrophy.
  • To evaluate the efficacy of superficial keratectomy as a treatment modality.

Main Methods:

  • Clinical presentation and histopathological examination of seventeen patients with superficial corneal dystrophy.

  • Surgical intervention using superficial keratectomy (15%-20% corneal thickness).
  • Assessment of visual outcomes post-treatment.

    • Main Results:

    • Lesions were subepithelial, primarily affecting Bowman's layer.
    • Superficial keratectomy resulted in good visual outcomes without the need for lamellar grafting.
    • Pathological findings showed similarities to classic granular dystrophy despite clinical differences.

    Conclusions:

    • A superficial corneal dystrophy distinct from classic granular dystrophy is identified.
    • Superficial keratectomy is an effective treatment for this condition.
    • A revised classification of granular dystrophy is proposed based on these findings.
