Summary

This study describes a rare bilateral ring-shaped corneal opacity, termed "Ascher-Ringe," characterized by distinct greyish dots in the outer stromal layers. The exact cause of this unusual finding remains unknown, with only a few cases documented.

Area of Science:

  • Ophthalmology
  • Corneal Diseases
  • Histopathology

Background:

  • Corneal opacities can arise from various conditions, impacting visual acuity.
  • Arcus lipoides and arcus senilis are common forms of corneal lipid deposition.
  • Understanding rare corneal anomalies is crucial for differential diagnosis.

Observation:

  • Two patients presented with an unusual bilateral, ring-shaped corneal opacity.
  • Biomicroscopy revealed minute greyish dots in the outer corneal stroma.
  • These dots formed a circular band resembling arcus lipoides, distinct from typical arcus senilis.

Findings:

  • The observed corneal anomaly is characterized by a unique ring-shaped pattern.
  • Histological examination showed deposits within the outer stromal layers.
  • This condition is distinct from other known corneal opacities, with limited prior reports.

Implications:

  • The proposed name 'Ascher-Ringe' aids in classifying this rare corneal condition.
  • Further research is needed to elucidate the etiology of Ascher-Ringe.
  • Accurate identification and naming can improve diagnostic accuracy and patient management.
