Prevalence of Vernal Keratonconjunctivitis: how many people are affected worldwide, differences by sex and region, with sources.
Vernal Keratoconjunctivitis (VKC) is a relatively rare form of chronic allergic conjunctivitis that primarily affects children and young adults. It is characterized by inflammation of the conjunctiva, the thin membrane covering the white part of the eye and the inner surface of the eyelids. VKC is more prevalent in certain geographic regions, particularly in warm climates.
The exact prevalence of VKC varies across different populations and studies. However, it is estimated that VKC affects approximately 2 to 9 per 10,000 individuals worldwide. The condition is more commonly found in males than females, with a male-to-female ratio ranging from 2:1 to 5:1.
VKC typically manifests during childhood or adolescence and may persist for several years before gradually improving or resolving in adulthood. The condition often follows a seasonal pattern, with symptoms worsening during spring and summer months.
While VKC is considered a relatively rare condition, it can significantly impact the quality of life for those affected. Prompt diagnosis and appropriate management by healthcare professionals are crucial in alleviating symptoms and preventing potential complications.
