Dimple Veiling

Staining

Symptoms

  • None to mild irritation
  • May disturb vision if on visual axis

Signs

  • Indentations display un-reversed illumination with white light illumination
  • Multiple, focal areas of sodium fluorescein pooling

Etiology

  • Indentations of epithelium resulting from air bubbles (rigid lenses) or mucin balls (soft lenses) trapped under lenses
  • Most frequently seen with ill-fitting GP lenses (air bubbles) or SiHy lenses (mucin balls)
  • In GPs, observed centrally with excessive pooling and peripherally with excessive edge lift

Prevalence

  • Occasional

Differential Diagnosis

Management

  • Refit GP lens with closer alignment to corneal shape
  • Flatter BOZR, smaller TD, change to toric back surface
  • Lens lubricants with EW SiHy, choose a lens with lower modulus
