In our work we propose to use the adult developmental eye movement test (A-DEM) of Gene Sampedro et al, for the study of saccadic movements in schizophrenia.

To study the importance of saccades and attention in a sample of institutionalized patients with schizophrenia in a Unit of Psychosocial Rehabilitation.

Sample formed by 30 people.15 patients and 15 controls. 15 patients were corresponding to all the schizophrenic patients admitted in January, 2009 in a Unit of Psycosocial Rehabilitation of Conxo's Psychiatric Hospital. The 15 of the group control were selected of random form between sanitary personnel without psychiatric pathology, homogenizing the variables chronological age and sex with regard to the group of investigation.

The A-DEM vertical half to 44.37 seconds in the control group versus 59.54 seconds in the sample of patients. Regarding the results of the horizontal A-DEM obtained an average score of 47.07 seconds compared to control group obtained 60.68 seconds in the group of patients. The schizophrenic patients are characterized for having an attention diminished in 87 %, opposite to 47 % of the group control that they have a normal attention and 40 % increased. These differences of saccadic movements and of the attention are statistically significant.

Schizophrenic patients have few saccades both horizontally and vertically slower than normal people.

Schizophrenic patients show a marked deficit of attention to the normal population.
