INTRODUCTION: This review presents the current in vitro and in vivo animal and human research on the roles of IL-8 in ocular inflammatory diseases. MATERIALS AND METHODS: Data sources were a literature review using Pub Med, Medline, and ISI databases (from 1990 to 2011). Search items included interleukine-8 (IL-8), CXCL8, chemokines, cytokines, alone or in combination with the, serum, aqueous, vitreous, eye, ocular, ocular tissues, ophthalmic, and review. RESULTS: IL-8 may be involved in primary or secondary ocular inflammations. Ocular effects of IL-8 differ based on the source of the secretion and site of the action. The most important effects of IL-8 in the eyes are angiogenic activities and induction of ocular inflammation. CONCLUSION: IL-8 plays important roles in ocular inflammation and angiogenesis in conjunctiva, cornea, iris, retina, and orbit. Anti-IL-8 targeted immunotherapy has been introduced as an important treatment modality, provided that IL-8 signal blocking takes place in desired areas and tissues.
