Therapeutic Management and New Upcoming Approaches for Age Related Macular Degeneration.

Abstract

Age-related Macular Degeneration (AMD) is a severe eye illness that is going to lead in the race for incurable blindness globally among the elderly population. AMD is the third common reason responsible for affecting the quality of life globally. The macula and the retinal layers are adversely affected during AMD and are responsible for the loss of vision eventually. Numerous genetic variables, lipid metabolism, ageing and oxidative damage are the causative factors in the genesis of AMD. Lack of antioxidants, smoking and excessive alcohol intake contribute to increasing the risk of AMD. Management of dry AMD involves the use of nutritional supplements like zinc and antioxidants, along with conventional treatment, however, the use of nutritional supplements can only give minor benefits on the progression of dry AMD. Later stages of AMD need to be managed by cell-based interventions where the damaged or lost cells are replaced with fresh donor cells. A plethora of treatment methods are used in the management of AMD, such as nutrition, antibody-based treatments, stem cell management and nanotherapeutics. The available expensive treatments come with a number of adverse effects and future developments require the involvement of risk factor modification approaches, personalized therapy, targeting the disease specific pathways, exploring better anti-vascular endothelial growth factor (VEGF) inhibitors and many other regenerative approaches, that will broaden techniques to diagnose, control and treat AMD. This review provides an overview of the progression of AMD and the causative factors, with considerable emphasises on the current and potential prospects.
