The incidence of age-related macular degeneration and its associated features increases with age and is low in people <55 years of age. [101] Smoking is the strongest modifiable risk factor. [102] As of 2008, age-related macular degeneration accounts for more than 54% of all vision loss in the white population in the US. [103]
An Amsler grid, artist's conception, as it might be viewed by a person with age related macular degeneration. Amsler grid can be used in detecting central visual field defects in following conditions: Age-related macular degeneration: The grid will help detecting the progression of AMD from dry form to wet form.

A retinal implant is a visual prosthesis for restoration of sight to patients blinded by retinal degeneration. The system is meant to partially restore useful vision to those who have lost their photoreceptors due to retinal diseases such as retinitis pigmentosa (RP) or age-related macular degeneration (AMD).
The eye not being tested is patched and the room lights are dimmed prior to commencement of the test. [12] The patient is positioned appropriately and comfortably against the forehead rest and chin rest. Minor adjustments to the head position are made to centre the pupil on the display screen to allow eye monitoring throughout the test.
Macular degeneration Visual field testing is widely used to monitor pathologies affecting the periphery of vision such as glaucoma . [ 4 ] During a conventional test, patients are asked to look steady (fixate) at a visual target, while light stimuli are projected at varying intensities in different retinal locations.
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
