Effects of a new dexamethasone-delivery system (Surodex) on experimental intraocular inflammation models.

Background: To investigate the effects of a new biodegradable dexamethasone drug delivery system, Surodex, in two experimental intraocular inflammation models; endotoxin-induced uveitis (EIU) and experimental autoimmune uveoretinitis (EAU).

Methods: Surodex was inserted into the right anterior chambers (ACs) of rats. In the EIU experiment, protein concentration, cell infiltration, and myeloperoxidase (MPO) activity in the aqueous humor were measured 24 h after injection.
