Abstract
Age-related macular degeneration (AMD) is one of the leading causes of low vision and blindness worldwide for people over age 60. By 2040, the number of people living with macular degeneration is expected to reach 288 million due to the exponential acceleration of population aging. A decline in visual functions caused by AMD has a significant economic impact in all countries. Besides aging, there are other multiple heterogenic risk factors associated with AMD: gender, environmental condition, lifestyle, genetic characteristics, chronic inflammatory processes in the human body, level of education, etc. It is important for the ophthalmologist to be aware of modifiable risk factors and thus to collect a comprehensive medical history, interact with patients using motivational interviewing and to involve promptly other healthcare specialists into the patient management strategy. Etiopathogenesis of AMD is still not entirely understood. However, it is known that the major pathways include age-related alterations of retinal pigment epithelium (RPE) cells, oxidative stress, dysregulated lipid metabolism, inflammation, hemodynamic changes, and neovascularization. Carotenoids lutein and zeaxanthin are natural compounds with a proven efficacy in reducing AMD progression, which have been demonstrated to act as medications for patients with early AMD stages. The micro- encapsulated formula offers such an advantage as gradual and controlled release of active substances. Keywords: age-related macular degeneration, risk factors, etiopathogenesis, carotenoids, lutein, zeaxanthin, microcapsules.
