Ocular motor disturbances are described with a miscellany of metabolic disturbances. Horizontal gaze abnormalities, often simulating congenital ocular motor apraxia, characterized Gaucher's disease. Vertical gaze abnormalities, especially downgaze paralysis, characterized what is generally considered a variant of Niemann-Pick disease, or sea-blue histiocytosis, but which we prefer to call the "DAF" syndrome. A form of internuclear ophthalmoplegia but with nystagmus of the adducting eye characterized abetalipoproteinemia. epileptiform eyelid and eye movements occurred in a case of methylmalonohomocystinuria. Ocular motor abnormalities are also described with variation of olivopontocerebellar degeneration and with ataxia telangiectasia.
