Hereditary nephropathies like cystinosis, nephronophthisis, and Alport syndrome commonly affect the eyes. Retinal degeneration is a primary cause of vision loss in these conditions, necessitating further research into treatments.

Area of Science:

  • Ophthalmology
  • Nephrology
  • Genetics

Background:

  • Ocular manifestations are frequently observed in hereditary kidney diseases.
  • Three specific hereditary nephropathies—cystinosis, nephronophthisis, and Alport syndrome—share common ocular pathologies.

Purpose of the Study:

  • To review and summarize the ocular findings in patients with cystinosis, nephronophthisis, and Alport syndrome.
  • To highlight the impact of these conditions on visual function and potential therapeutic avenues.

Main Methods:

  • Retrospective analysis of ocular examinations in patients with diagnosed hereditary nephropathies.
  • Review of clinical symptoms, histological findings, and electroretinogram (ERG) results.

Main Results:

  • Infantile cystinosis affects corneal and retinal epithelium, with retinal involvement causing blindness.
  • Nephronophthisis presents with varying degrees of chorioretinal degeneration and ERG alterations.
  • Alport syndrome cases showed anterior lenticonus impacting visual acuity and retinopathy without vision loss.

Conclusions:

  • Ocular complications, particularly retinal degeneration, are significant in these hereditary nephropathies.
  • Topical cysteamine shows promise for cystinosis but requires further investigation.
  • Early detection and understanding of ocular involvement are crucial for managing these genetic disorders.
