Alport syndrome patients showed ocular fundus changes in 35.3% without affecting visual acuity. However, contrast sensitivity and electroretinography (ERG) revealed significant functional vision impairments.

Area of Science:

  • Ophthalmology
  • Genetics
  • Medical Imaging

Context:

  • Alport syndrome is a rare genetic disorder affecting the kidneys, ears, and eyes.
  • Ocular manifestations are common but their impact on visual function requires further elucidation.

Purpose:

  • To investigate the prevalence of ocular fundus changes in Alport syndrome patients.
  • To assess the functional visual impact, including contrast sensitivity and electroretinography (ERG) findings.

Summary:

  • Ocular fundus changes were observed in 35.3% of 17 Alport syndrome patients.
  • No significant impact on central visual acuity was noted.
  • A statistically significant reduction in contrast sensitivity was detected.
  • Electroretinography (ERG) revealed significant alterations in 'a' and 'b' wave steepness and 'b' wave amplitude.

Impact:

  • Highlights subclinical visual impairments in Alport syndrome.
  • Suggests the utility of contrast sensitivity testing and ERG for comprehensive patient evaluation.
  • Informs potential strategies for monitoring and managing visual complications in Alport syndrome.
