Chorioretinitis as a first sign of SSPE.

Subacute sclerosing panencephalitis (SSPE) is a progressive neurodegenerative disorder. Ocular involvement in SSPE has been well known and might be seen in 42 to 50% of the patients. Visual findings are generally seen at stage III with neurological abnormalities. Ophthalmologic involvement might be preceding typical SSPE symptoms.
