Summary

Male eyes have larger optic discs than female eyes, with disc size correlating to axial length. These findings help explain variations in optic disc measurements across studies.

Cataract and optic disk drusen in a patient with glycogenosis and di George syndrome: clinical and molecular report.

BMC ophthalmology·2017

Area of Science:

  • Ophthalmology
  • Ophthalmic Morphology
  • Biometry

Background:

  • Optic disc size and its correlation with ocular parameters require further investigation.
  • Previous studies have reported conflicting data on optic disc morphometry.

Purpose of the Study:

  • To evaluate optic disc correlations in normal eyes using computer-aided morphometry.
  • To investigate sex-based differences in optic disc area and axial length.
  • To determine the relationship between axial length, disc area, and refraction.

Main Methods:

  • Computer-aided morphometry was used to analyze optic disc parameters.
  • A sample of 235 subjects (144 women, 91 men) with normal eyes was studied.
  • One eye per patient was randomly selected for statistical analysis.

Main Results:

  • Statistically significant differences were found in disc area (P < 0.05) and axial length (P < 0.0001) between sexes.
  • Axial length correlated with disc area in both females (r=0.55) and males (r=0.35).
  • Axial length also correlated with refraction in both females (r=0.40) and males (r=0.50).

Conclusions:

  • Optic disc area is larger in male eyes compared to female eyes, influenced by axial length differences.
  • Disc size is correlated with axial length, a key factor in optic disc morphometry.
  • Variations in male/female ratios within study samples may explain discrepancies in previous optic disc measurement findings.
