Stability of the electric sensitivity threshold of the visual analyzer in case of five repeated investigations

Purpose: to evaluate the stability of the electric sensitivity threshold (EST) parameter in a series of fve measurements in patients with the vision pathology. Material and Methods. 66 patients (129 eyes) took part in the investigation with the age ranging from 12 to 82 with diferent ophthalmic pathologies and without them. In each case a series of fve measurements (EST) was performed using ESOM-Komet devise according to the standard program. Results. Five typological groups were revealed which difered reliably as per the tendencies of EST level changes in the course of fve successive measurements. In 80 % of the cases the successive EST values turned out to be practically stable. In 20 % of the cases there was observed a high EST variability with the signifcant trend towards a gradual growth of EST level. The nature interrelation analysis of EST successive charges depending on the diagnosis, age, sex, initial EST level didn»t reveal signifcant relations. Conclusion. The performed series of measurements can be regarded as a highly simplifed model of monitoring the visual system condition in dynamics. The absence of stability / instability interrelation with the clinical data points to the necessity to investigate the criteria and strategy of taking the decision in patients in the course of the diagnostic procedures.
