The following are other diagnostic considerations:

  • Dry eye syndrome - Poor tear lake or a decreased tear break-up time
  • Blepharitis - Erythema, telangiectasias, and crusting of the eyelid margins
  • Trauma - Can occur from relatively mild trauma, such as chronic eye rubbing
  • Exposure keratopathy - Poor eyelid closure with failure to cover the entire globe
  • Topical drug toxicity - Neomycin, tobramycin, or drops with preservatives, including artificial tears
  • Contact lens–related disorder - Chemical toxicity, tight-lens syndrome, contact lens overwearing syndrome, or giant papillary conjunctivitis
  • Thygeson superficial punctate keratitis (SPK) - Bilateral, recurrent SPK without conjunctival injection
  • Foreign body under the upper eyelid - Typically linear SPK with fine scratches arranged vertically
  • Trichiasis and/or distichiasis - Eyelashes rubbing on the cornea
  • Entropion or ectropion - Superior or inferior SPK
  • Floppy lid syndrome - Extremely loose lids that pull away from the eye very easily
  • Associated retinopathy - Sun-gazer retinopathy associated with ultraviolet (UV) keratitis, seen particularly in psychiatric patients who stare directly into the sun
