Abstract

A facile ionic cross-linking strategy was exploited to construct a dexamethasone sodium phosphate (Dex) supramolecular hydrogel composed of Dex and calcium ion. Intravitreal injection of Dex hydrogel displayed excellent intraocular biocompatibility without causing the complications of fundus blood vessel tortuosity and lens opacity. More importantly, the proposed Dex hydrogel exhibited a comparative anti-inflammatory response to native Dex formulation on an experimental autoimmune uveitis (EAU) model via the downregulation of Th1 and Th17 effector responses.
