Summary

This study examined posterior keratoconus in two patients, revealing central corneal thinning and haze. Endothelial cells remained healthy, suggesting a localized posterior corneal issue.

Area of Science:

  • Ophthalmology
  • Corneal Diseases
  • Human Genetics

Background:

  • Posterior keratoconus is a rare corneal condition.
  • Understanding its presentation is crucial for diagnosis and management.

Observation:

  • Slit-lamp examination showed central corneal thinning and stromal haze beneath the endothelium.
  • Photokeratoscopy did not indicate anterior keratoconus.
  • Wide-field specular microscopy revealed normal endothelial cell density and morphology.

Findings:

  • The study details the clinical and microscopic findings in three eyes with posterior keratoconus.
  • Corneal haze and thinning were localized to the posterior stroma.
  • Endothelial cell health was preserved despite the posterior corneal abnormalities.

Implications:

  • These findings contribute to the understanding of posterior keratoconus pathophysiology.
  • Preserved endothelial function may have implications for surgical management.
  • Further research is needed to elucidate the genetic and developmental basis of this condition.
