Abstract
Glaucoma is a chronic eye disease and the second most leading cause of irreversible impaired vision in the world, which is primarily linked with high intraocular pressure (IOP). The treatment of glaucoma is currently challenging due to the innate mechanics of ocular barriers that limit the penetration of ophthalmic drugs. To tackle this, various carriers (inorganic-, polymeric-, hydrogel-, or contact lens-based) with specialized physical and chemical properties have been intensively studied. These carriers-drug formulations have shown significant improvement in various aspects such as ocular barriers penetration, bioavailability, sustained release of drug, tissue targeting, and lowering the IOP. The delivery systems can be administered through various routes (intravitreal or periocular injection, or systemic route), enabling the drugs to reach the damaged sites and help to recover the damaged optical nerves, thus considered an effective treatment strategy for glaucoma. In this review, we thoroughly investigate the recent advances in ocular delivery formulations focusing on glaucoma, including nanocarrier types, delivery route, and the efficacy in vitro and in vivo, clinical availability, and future outlook.
