ABSTRACT
The classifi cation of allergic ocular diseases is still a matter of debate. However, traditionally it encompasses different groups (Fig. 1): seasonal/ chronic allergic conjunctivitis (SAC/PAC), vernal keratoconjunctivitis (VKC), atopic keratoconjunctivitis (AKC), and giant papillary conjunctivitis (GPC). Moreover contact dermatoconjunctivitis (CDC) may be included in this category.
