Staining– Superior Epithelial Arcuate Lesion (SEAL)

Symptoms

  • None to mild discomfort

Signs

  • Superficial arcuate staining of superior cornea. Lesion is between 10 and 2 o’clock and is parallel to limbus. Often unilateral and asymmetric

Etiology

  • Arcuate disruption of the peripheral corneal surface sparing the limbus
  • Likely to occur in superior region of cornea normally covered by the upper eyelid

Prevalence

  • Rare. More common with EW and with stiffer lens materials (SiHy)

Differential Diagnosis

Management

  • Closely monitor for resolution if associated with EW lenses
  • If staining is more severe, then cessation of wear is required with the addition of rewetting drops
  • Refit if persistent to a daily disposable, a higher water content, a more aspheric back surface, or a lower modulus material
