The present study has the purpose of relating the capacities of visual retention with the Benton Visual Retention Test and the level of coma depth, which is measured with the GCS (Glasgow Coma Scale). 31 subject suffering cranioencephalic damage admitted to the intensive care unit (ICU) have been studied. GCS scores were obtained during their stay in the intensive care unit and the Benton Visual Retention Test was administered after hospital discharge. The procedure followed consists in comparing the performance of subjects with higher GCS scores to subjects with lower values when executing administration. A of form C of BVRT. We could conclude as follows: firstly that BVRT is a useful tool to detect the existence of brain damage; secondly, indexes of brain damage presence with BVRT are: a low figure in correct design, more errors, less errors in distortion and rotation; more errors in the left visual hemifield. Thirdly, the depth of coma is a good prognosis index on BVRT execution and in consequence of visuo-constructive abilities.
