Visual Health Nanocomposites: Present and Future

Background: In recent years, the therapeutics for eye diseases as retinopathy diabetic, dry eye, glaucoma and contact lenses fabrication are including nanocompounds as ocular drug delivery systems, biomarkers for detection of eye diseases, copper and silver ions that has been incorporated by means of the nanotechnology for the production of less toxic and more effective alternatives. Several compounds such as silver nanoparticles, turmeric-based nanocomposites, neovascularization blockers and nanoparticles extracted from the plant Costus pictus among others have been researched for this purpose. Those compounds are some of the promising research efforts that are studying and will contribute to preventing vitreous hemorrhages and ocular manifestations that affect large populations, being one of the main causes of blindness in the world. Although, nanotechnology has a lot of contributions which are advantageous for several medicinal areas.
