Cold weather can cause reversible corneal edema in susceptible individuals. Wearing contact lenses effectively prevented this condition in a case study.

Area of Science:

  • Ophthalmology
  • Corneal Diseases
  • Environmental Ophthalmology

Background:

  • Corneal edema, or swelling of the cornea, can be triggered by various factors.
  • Cold-induced corneal opacification is rare, with suggested links to Raynaud's disease or trigeminal neuropathy.

Observation:

  • A patient experienced recurrent, reversible corneal edema in the right eye following exposure to cold stress.
  • Symptoms were consistently triggered by cold weather activities, such as cycling.
  • A provocation test confirmed transient corneal edema after cold exposure.

Findings:

  • The patient's condition was not attributable to Raynaud's disease or trigeminal neuropathy, confirmed by diagnostic tests.
  • Contact lens wear was identified as an effective prophylactic measure against cold-induced corneal edema.

Implications:

  • This case highlights an unusual presentation of cold-induced corneal edema.
  • Contact lenses may serve as a viable preventative strategy for similar cases.
  • Further research into the mechanisms of cold-induced corneal edema is warranted.
