About InSite Vision

InSite Vision is advancing new ophthalmologic products for unmet eye care needs based on its innovative DuraSite® platform technologies.

InSite Vision is also advancing AzaSite Plus, a novel ophthalmic therapeutics through Phase 3 clinical studies for the treatment of eye infections, and is preparing two new drug applications (NDA) for the commercial approval by the U.S. Food and Drug Administration (FDA): BromSite for the treatment of inflammation and prevention of pain associated with cataract surgery and DexaSitefor the treatment of blepharitis.
