Opacities

Central Scarring with Semi-Scleral Contact Lens

Central Scarring with Semi-Scleral Contact Lens

Opacities

Stromal scar

Symptoms

  • None if opacity is small and peripheral
  • Decreased vision and photophobia for larger, more central opacities

Signs

  • Opaque area within the stroma
  • Staining may occur if lesion is active. True “scar” does not stain, but may pool fluorescein if the area has a depression associated with it
  • Absence of accompanying signs

Etiology

  • Corneal opacification may result from a variety of inflammatory conditions, previous corneal surgery, or trauma affecting the stroma
  • Damage to the stroma will usually leave a residual scar
  • Opacity may be long-standing and of no relevance to current wearing habits

Prevalence

  • Occasional

Differential Diagnosis

Management

  • Determine if active inflammation is present and treat cause
  • The presence of an inactive region of opacification requires no treatment
  • Size and location of the opacity must be documented for future reference
  • Presence of scars may indicate increased risk for future inflammatory complications. Wearing and visit schedule should be monitored appropriately
