prescribed or over-the-counter eye medication, except artificial tears or eye

wear.

- Active ocular disease is defined as infection or inflammation which requires
therapeutic treatment. Mild (i.e. not considered clinically relevant) lid
abnormalities (blepharitis, meibomian gland dysfunction, papillae), corneal and
conjunctival staining and dry eye are not considered active ocular disease.
Neovascularization and corneal scars are the result of previous hypoxia, infection or
inflammation and are therefore not active.
