Latex allergy allergy is an IgE (immune) mediated reaction to proteins found in the "Hevea brasiliensis" tree, a type of rubber tree. Testing for type I natural rubber latex allergy is through blood testing to determine if the patient is producing IgE antibodies to latex proteins. Anaphylactic shock can be provoked in allergic persons by the "previous" use of latex in an area: latex is typically powdered to prevent sticking, latex proteins become attached to the particles of powder, and the powder becomes airborne when the latex item is used, triggering potentially life-threatening Type I reactions when the latex-contaminated powder is inhaled
Allergic conjunctivitis forms of allergic conjunctivitis such as vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC). Both vernal keratoconjunctivitis and atopic keratoconjunctivitis are chronic allergic diseases wherein eosinophils, conjunctival fibroblasts, epithelial cells, mast cells, and TH2 lymphocytes aggravate the biochemistry and histology of the conjunctiva. VKC is a disease of childhood and is prevalent in males living in warm climates. AKC is frequently observed in males between the ages of 30 and 50. VKC and AKC can be treated by medications used to combat allergic conjunctivitis or the use of steroids.
