Living with Vernal keratoconjunctivitis

A long-lasting, severe allergy of the eye surface that often flares in spring and summer, mostly in boys.

Understanding Vernal keratoconjunctivitis

Vernal keratoconjunctivitis (VKC) is a chronic, severe allergy that affects the surfaces of the eyes.

It most often affects boys in warm, dry climates and often starts in childhood. Flares are common in spring and summer but can return in winter. GARD says it is caused by an allergic reaction to allergens in the air.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Itchy eyes
  • Red eyes
  • Extreme sensitivity to light (photophobia)
  • Increased tearing
  • Blurred vision
  • Feeling of something in the eye

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include eye disease specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
