Summary

Meretoja syndrome causes corneal nerve damage, leading to increased stromal haze and reduced nerve visibility. This nerve degeneration correlates with the severity of clinical symptoms in affected patients.

Area of Science:

  • Ophthalmology
  • Neurology
  • Genetics

Background:

  • Meretoja syndrome is a rare genetic disorder characterized by systemic amyloidosis.
  • Ocular manifestations, including corneal changes, are common in Meretoja syndrome.

Purpose of the Study:

  • To investigate the relationship between clinical symptoms and corneal nerve changes in Meretoja syndrome.
  • To assess corneal stromal haze and nerve visibility using scanning slit confocal microscopy.

Main Methods:

  • Slit-lamp microscopy and scanning slit confocal microscopy were performed on three patients.
  • Corneal nerve visibility and stromal haze were quantified and correlated with clinical findings.

Main Results:

  • Stromal haze intensity positively correlated with symptom severity.

  • Epithelial and stromal nerve visibility inversely correlated with symptom severity.
  • Amyloid deposits were observed near corneal nerves, and severe cases showed no visible nerves.

    • Conclusions:

    • Meretoja syndrome significantly impacts corneal nerves, causing damage and degeneration.
    • Confocal microscopy reveals a correlation between corneal nerve integrity and clinical disease severity.
    • This study highlights the neurodegenerative aspect of Meretoja syndrome affecting the cornea.
