Clinical features of optic neuritis in adults differ from those in children, who often pre sent with atypical clinical manifestations and results of some investigations. This makes the diagnosis of optic neuritis a demanding task. Some investigations, such as the Haitz test, contrast sensitivity test and vision field test, are less reliable in children than in adults. Electrophysiological investigations are the most accurate diagnostic tool for the assessment of optic neuritis in children. This study involved all childrenreferred to the Department of Ophthalmology, University Medical CentreLjubljana, because of suspected optic neuritis during the past two years. The children were invariably evaluated by the vision field testing, Haitz test, contrast sensitivity test and electrophysiological investigations,including flash and pattern electroretinography (ERG) and visual evoked potentials (VEP). The results were compared with those obtained in a group of healthy volunteers of the same mean age. The diagnosis of optic neuritis should always be considered in a child presenting with a considerablyreduced visual acuity refractory to corection in the presence of anormal ophthalmologic status, associated with disc hyperaemia, blurred optic disc margins, relative afferent papillary defect, or subjective problems, suchas blurred vision, double vision and painful eye movements. The diagnosis of optic neuritis cannot be made on the grounds of clinical findings alone, especially in children with a relatively well preserved visal acuity. In our study, 3 children with suspected optic neuritis had delayed and decreased VEP but normal flash and pattern ERG. Since the results were not veery convincing,the children will be followed up.
