[Eales's disease with neurological involvement (author's transl)].

A moroccan male aged 26, with Eales's disease since 6 years, develops a low thoracic level paraplegia over 2 months. Examination then also points out an horizontal nystagmus. CSF changes are important: 292 cells/mm3 (96 p. 100 lymphocytes), 3,80 g/l proteins. Slight improvement is obtained by corticosteroid therapy. This case is compared with those of the literature, mostly myelopathies. The pathogenetic problems of immuno-allergic type are discussed.
