Medicinal allergic conjunctivitis at children develops against the background of use of various eye drops. The allergy can arise both on the main active ingredient, and on the preservatives used in drops; especially often allergic conjunctivitis at children arises at instillation of antibacterial eye drops and anesthetics.

Infectious and allergic conjunctivitis at children is connected with an organism sensitization to microbic allergens: to bacterial, virus, fungal ekzotoksina. At the same time the activator in a conjunctiva of an eye is not found.

Tubercular and allergic damage of eyes proceeds as a keratokonjyunktivit, with simultaneous defeat of a conjunctiva and cornea. This form of an allergoz is a consequence of allergic reaction to the waste products of mikobakteriya of tuberculosis circulating in blood.

For confirmation of the diagnosis the microscopic research of plaintive liquid where at allergic conjunctivitis at children, over 10% of eosinophils are found is conducted. At the allergic nature of a disease the level of the general IgE increased in comparison with age norm, an eozinofiliya also comes to light. In the presence of a purulent secret the bacteriological research separated from a conjunctival cavity is conducted.
