Papillary hyperplasia is the excessive proliferation of the conjunctival epithelium and infiltration of polymorphonuclear leukocytes. Under the slit lamp, some dilated capillaries can be seen in the center of each papilla, spreading out in a spoke-like manner, with a tiny papillary or velvety appearance. A giant papilla is greater than 1 mm in diameter. Spring conjunctivitis, contact lenses.

The follicular conjunctival epithelium is characterized by localized accumulation of lymphocytes, which appear as hemispherical bulges with no blood vessels in the center and blood vessels surrounding the follicles. Seen in most viral conjunctivitis.
