title: Chorioretinitis as a possible very early manifestation of subacute sclerosing panencephalitis.
abstract: Ocular changes occur in up to 50% of cases of subacute sclerosing panencephalitis (SSPE) usually at the same time as other neurological signs. Occasionally, visual symptoms precede other manifestations by a few weeks or months. Fundal changes (most commonly a macular chorioretinitis) are the most frequent ocular manifestation of SSPE. Inclusion bodies occur in the retina of patients with chorioretinitis and SSPE and it is believed that the lesions are due to actual viral invasion. We report a case of SSPE in which an atypical chorioretinitis preceded the onset of the typical clinical features of the disease by almost two years. Our case is unusual because of the long interval between the visual symptoms and the onset of other features of SSPE. We wish to emphasise the importance of thinking of SSPE in cases of chorioretinitis which are atypical or occur in young patients. Although treatment of SSPE thus far has been mostly disappointing, earlier diagnosis may offer the hope of better results.
