Abstrakt		Introduction: The study of visual maturation in children is still an active field of research. Morphological and functional changes are most pronounced in the first few years of human life when central retina, myelinisation of visual pathway and visual cortex exhibit fast development. Maturation of visual pathway can be studied with clinical and electrophysiological (ERG, VEP) evaluation. With electroretinogmphy (ERG) the function of the retina can be objectively studied and with visual evoked potential (VEP) the function of the rest of the visual pathway. Electrophysiological testing of infants and preschool children is still not standardized. Therefore, results of different visual electrophysiology laboratories can not be directly compared and it is therefore important that every paediatric visual electrophysiology laboratory perform normative data of electrophysiological responses on their population of healthy children. In Slovenia the study of maturation of visual function has not been performed in infants and preschool children. AIM: With clinical evaluation of visual function and with electrophysiological methods the developmental changes in visual function in healthy infants and preschool children were investigated. The correlation between the clinical and electrophysiological evaluation of the visual function was also studied. The obtained data served as normative data for ERG end VEP evaluation of visual pathway in infants and preschool children. HYPOTHESIS: I. Due to intensive morphological changes in visual pathway a rapid improvement in the visual acuity and considerable changes in electrophysiological responses were expected. 2. It was assumed that clinical evaluation of visual acuity relates to maturation of electrophysiological responses. (Abstract truncated at 2000 characters)
