Glaucoma is an ocular disease featuring increased intraocular pressure (IOP) and its primary treatment strategy is to lower IOP by medication. Current ocular drug delivery in treating glaucoma is confronting a variety of challenges, such as low corneal permeability and bioavailability due to the unique anatomical structure of the human eye. To tackle these challenges, a cubosome drug delivery system for glaucoma treatment was constructed for timolol maleate (TM) in this study. The TM cubosomes (liquid crystalline nanoparticles) were prepared using glycerol monooleate and poloxamer 407 via high-pressure homogenization...

Over the past decade, great strides have been made in the management of diabetic macular edema (DME). Therapeutic alternatives now include focal/grid laser photocoagulation, vitreo-retinal surgery, and intraocular injection of anti-angiogenic and steroid molecules. Intravitreal administration of steroids represents a fundamental alternative for recalcitrant and naive eyes with DME, especially in those cases when anti-vascular endothelial growth factor (VEGF) agents are contraindicated or a treatment regimen with fewer intravitreal injections is required...
