Optic disk size varies with refractive error, increasing in high myopia beyond -8 diopters and decreasing in high hyperopia beyond +4 diopters. These findings refine definitions for myopia and hyperopia.

Area of Science:

  • Ophthalmology
  • Optometry
  • Medical Imaging

Background:

  • Refractive error significantly influences ocular structures.
  • Understanding optic disc size in relation to refractive error is crucial for diagnosing optic nerve conditions.
  • Previous studies suggest a link, but specific thresholds require further investigation.

Purpose of the Study:

  • To determine the refractive error range influencing optic disc size.
  • To identify refractive error thresholds where optic disc size becomes dependent or independent.
  • To investigate the relationship between optic disc area and refractive error.

Main Methods:

  • Clinical observational study involving 1999 eyes from 1011 subjects.
  • Morphometric evaluation of optic disc photographs.

  • Analysis of refractive errors ranging from -24.25 to +9.4 diopters.

    • Main Results:

    • A curvilinear relationship was observed between optic disc area and refractive error.
    • Optic disc area increased significantly in high myopia, starting beyond -8 diopters.
    • Optic disc area decreased in high hyperopia, starting beyond +4 diopters.

    Conclusions:

    • Optic disc size is dependent on refractive error, particularly in high myopia and hyperopia.
    • The identified thresholds of -8 diopters for myopia and +4 diopters for hyperopia warrant consideration for refining diagnostic definitions.
    • Findings support histomorphometric data, emphasizing the clinical relevance of these refractive error ranges.
