IL-4 may contribute to the development of seasonal allergic conjunctivitis.

RSV may be a significant pathogenic factor in allergic conjunctivitis.

We questioned whether IL-4 related phenomenon occurred on the surface of the conjunctiva during allergic conjunctivitis.

The pathogenesis of allergic conjunctivitis is largely conjectural.

In order to further investigate the relation of RSV and allergic conjunctivitis, we performed an animal study.
