Average values of the visual evoked potential in patients of Clínica de Optometría of Universidad de La Salle in ages between the 15 years and 50 years with the team LKC Technologies

Abstract

<em><strong>Objective:</strong></em> To Determine mean values of visual evoked potential (VEP) in patients (ages from 15 to 50 years) who had visit the Optometric Clinic of The La Salle University, the patients were evaluated with the LKC Technologies equipment. The specific objectives were: determine differences in the evoked visual potential between men and women, compare the findings of (VEP) of the patients of the sample with the mean values of the standard protocol of the Monpack 3 equipment and to compare the values of the used patterns of the VEP LKC Technologies 6’, 12’, 25’ y 50’ according to age using 2 intervals 15 to 30 years and 31 to 50 years. Methods and materials: the sample was 40 eyes (20 patients) with ages from 15 to 30 years , this patients were evaluated with the VEP pattern and flash, there was made a comparison between the 2 values and between patients according to gender (men and women), this values were compared with the suggested values by Metrovision for the use of the electrophysiology ewuipment Monpack 3 and there were compared de VEP pattern of 6’,12’,25’ y 50’ minutes of arc between the 2 age groups. <em><strong>Results:</strong></em> The VEP values between men and women had no clinical significative differences; however there is a little difference in the latency in masculine gender. The VEP values of the LCK technologies equipment compared to the Monopack 3 values showed statistical differences, but no of clinical value. The comparison between age groups didn’t show statistical differences. <em><strong>Conclusion:</strong></em> by the means of the clinical analysis we conclude that the findings are the same with both equipments LCK technologies and Monopack 3.
