title: Uhthoff's syndrome.
abstract: A total of 125 patients with a previous episode of optic neuritis was followed to assess the subsequent prevalence of transient visual blurring. 32.8 per cent developed this symptom and the precipitating factors were identified. No correlations were found between the development of the symptom and the parameters of optic nerve function studied.
