Abstract
Formulations for controlled, sustained release of biologically active agents for the treatment of ocular disorders have been developed. These formulations are based on solid microparticles formed of the combination of biodegradable, synthetic polymers such as poly(lactic acid) (PLA), poly(glycolic acid) (PGA), and copolymers thereof. The microparticles are characterized by low burst levels and efficient drug loading and sustained release.
