Entoptic : Entoptic events are the result of internal factors causing the sensation that there is an object or image. Examples are phosphenes or flashes that occur when the vitreous is pulled on. Colorful dots are sometimes seen in the visual field against a hazy background. These can occur because stimuli other than photons can trigger the photoreceptor cells or other cells en route to the optic nerve.
