Peripheral retinal changes are common in eyes with longer axial lengths, indicating increased myopia. Pavingstone degeneration correlates with older age, while white without pressure and retinal holes/tears are linked to younger age.

Area of Science:

  • Ophthalmology
  • Retinal Science
  • Myopia Research

Background:

  • Axial myopia is a significant risk factor for various peripheral chorioretinal changes.
  • Understanding these associations is crucial for managing high myopia and preventing complications.

Purpose of the Study:

  • To investigate the correlation between peripheral chorioretinal changes and axial length in myopic eyes.
  • To identify specific lesions associated with increased axial length and demographic factors.

Main Methods:

  • A-scan ultrasonography (immersion technique) measured axial length in 513 myopic eyes (≥24 mm).
  • Biomicroscopic examination with scleral indentation assessed peripheral retinal findings.
  • Prevalence of lattice degeneration, pavingstone degeneration, pigmentary degeneration, white with or without pressure (WWP), retinal holes/tears (RHT), retinal detachment, and posterior vitreous detachment (PVD) was recorded.

Main Results:

  • Significant correlations were found between longer axial length and lattice degeneration, pavingstone degeneration, WWP, and PVD.
  • Pavingstone degeneration showed a significant relationship with older age.
  • WWP and RHT were significantly associated with younger age.
  • Retinal detachment and pigmentary degeneration did not show a significant correlation with axial length.

Conclusions:

  • Peripheral chorioretinal changes are prevalent in eyes with increased axial length, particularly lattice degeneration, pavingstone degeneration, WWP, and PVD.
  • Age influences the occurrence of specific lesions like pavingstone degeneration and WWP/RHT.
  • These findings highlight the importance of regular retinal examinations in myopic individuals to detect and manage potential complications.
