entoptic

adj. originating within the eyeball itself. The term is used particularly to denote visual sensations caused by stimulation within the eye (entoptic phenomena), the classic example of which is seeing faint dark specks moving through the visual field when gazing at a clear, blue sky. These are shadows caused by blood cells moving through the vasculature on the surface of the retina.
