Interest in the development of visual acuity in young infants is increasing. At this age a reliable estimation of visual function is hazardous. This paper highlights the role of flash- and pattern evoked visual potentials. Flash evoked potentials are valuable in following development and/or recovery of visual acuity intra-individually as well as in providing an estimation of sensitiveness to light. Pattern evoked potentials may give an estimation of maturation of the visual system: these potentials also give an objective measurement of visual acuity.

D014785	Vision, Ocular	The process in which light signals are transformed by the PHOTORECEPTOR CELLS into electrical signals which can then be transmitted to the brain.

D014792	Visual Acuity	Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.	Acuities, Visual,Acuity, Visual,Visual Acuities
