Tests and diagnosis

By Mayo Clinic Staff

Tests and procedures used to diagnose blepharitis include:

  • Examining your eyelids. Your doctor will carefully examine your eyelids and your eyes. He or she may use a special magnifying instrument during the examination.
  • Swabbing skin for testing. In certain cases, your doctor may use a swab to collect a sample of the oil or crust that forms on your eyelid. This sample can be analyzed for bacteria, fungi or evidence of an allergy.
