    Area of Science:

    • Ophthalmology
    • Corneal Science

    Background:

    • Deep corneal layer alterations, like Hassall-Henle bodies, are common in aging.
    • Descemet's membrane and endothelial changes stem from various causes like dystrophy, infections, and trauma.

    Observation:

    • Six cases presented with exclusive clear vesicles and scalloped lesions at the Descemet's membrane and endothelial level.
    • These polymorphic changes were extensive in some cases.

    Findings:

    • Despite extensive changes, visual acuity and corneal physiology remained normal.
    • The exact cause was uncertain, suggesting a dystrophic origin or nonfamilial posterior corneal vesicles.

    Implications:

    • Highlights the potential for significant posterior corneal changes without compromising visual function.
  • Suggests a need for further research into the etiology of these nonfamilial posterior corneal vesicles.
