Summary

Abnormal optic disc shape is linked to corneal astigmatism. Routine eye exams in children should include refractometry to detect corneal astigmatism and prevent amblyopia, as disc shape can indicate astigmatism axis.

Area of Science:

  • Ophthalmology
  • Optometry
  • Corneal and Refractive Surgery

Background:

  • The cornea and optic disc are key structures at the sclera's anterior and posterior openings.
  • Abnormalities in these structures can impact visual function.

Purpose of the Study:

  • To investigate the association between abnormal optic disc shape and corneal astigmatism.
  • To determine if optic disc morphology can predict corneal astigmatism and guide its management.

Main Methods:

  • A cross-sectional study involving 882 participants (430 women, 452 men) aged 8-87 years.
  • Corneal astigmatism measured by keratometry; optic disc morphometry analyzed from photographs.
  • Key metrics included corneal astigmatism, optic disc diameter ratio, and optic disc form factor.

Main Results:

  • Significant correlation found between corneal astigmatism and elongated optic disc shape (P < 0.001).
  • Higher corneal astigmatism observed in eyes with tilted discs (P < 0.01) and smaller in circular discs (P = 0.006).
  • Elongated discs and high corneal astigmatism were associated with amblyopia (P < 0.05); disc orientation correlated with astigmatism axis.

Conclusions:

  • Abnormal optic disc shape is significantly correlated with corneal astigmatism.
  • Recommend refractometry for children with abnormal optic disc shape to detect and prevent amblyopia.
  • Optic disc diameter orientation may indicate the axis of corneal astigmatism.
