A first glimpse into disc shedding in the human eye

An elusive biological cycle in the eye - the daily disposal and regeneration of the end tips of photoreceptor cells - has been captured in images for the first time in a living human eye. Photoreceptors are light-sensitive cells responsible for initiating vision. This glimpse into the inner workings of the eye will help scientists better understand, prevent and manage major eye diseases that affect photoreceptors like age-related macular degeneration and retinitis pigmentosa.
