Summary

This study examined 1485 patients, identifying 199 peripheral mosaic patterns and 10 posterior crocodile shagreens. Both corneal conditions were found to be age-related.

Area of Science:

  • Ophthalmology
  • Corneal Science

Background:

  • Corneal mosaic patterns are infrequently documented.
  • Understanding their prevalence and characteristics is crucial for clinical diagnosis.

Purpose of the Study:

  • To investigate the prevalence and characteristics of mosaic patterns in the cornea.
  • To differentiate peripheral mosaic patterns from corneal arcus.
  • To describe the morphology of posterior crocodile shagreen.

Main Methods:

  • Examination of 1485 consecutive patients' corneas.
  • Identification and classification of observed corneal patterns.
  • Analysis of age-related prevalence and distinct features.

Main Results:

  • 199 peripheral mosaic patterns were identified.
  • 10 posterior crocodile shagreens were observed.
  • Peripheral mosaic pattern is age-related and distinct from corneal arcus; posterior crocodile shagreen is also age-related.

Conclusions:

  • Peripheral mosaic pattern and posterior crocodile shagreen are age-related corneal findings.
  • Morphological characteristics of these patterns warrant further discussion for diagnostic clarity.
