  Purpose: To direct attention to a generally ignored cognitive element in chiasmal symptomatology, with the aim of reducing the diagnostic delay in such cases, where complaints are typically vague. A minority of chiasmal patients thus present with cognitive ignorance or mis-interpretation in visual space, probably caused by conductive loss of information as usually required for higher brain centres to induce relevant eye movements. Methodology: Personal experience from more than 30 years’ neuro-ophthalmological service is overviewed, primarily based on observation of abnormal behaviour during routine clinical testing for visual acuity (eventually summing up to 64 patients). Neuro-psychological testing and extended imaging (including functional positron emission tomography imaging as a pilot study) were carried out in part of the series... View More»
