Clinical regulation of asthenopia severity based on the "CVS-22" quality of life questionnaire for patients with computer visual syndrome

Objective: clinical regulation of the severity of asthenopia based on the data of the questionnaire for the quality of life of patients with computer visual syndrome "CVS-22". Material and methods. Under supervision there were 204 patients with "normal" indicators of objective accommodation and not presenting asthenopic complaints, as well as with symptoms of accommodative asthenopia. All patients were once examined according to the "CVS-22" questionnaire with the calculation of the total test indicator (TTI). The basis for clinical normalization was the analysis of the indicators of sensitivity (ISEN) and specificity (ISP) with the formation of standard ROC curves. Results. The "area" under the ROC curve was 0.939, which indicates the "excellent" predictive quality of the model. At the point of maximum ISEN (83%) and ISP (86%), the value of TTI was 175 points, which determines this value from the position of "norm". The final check of the developed model showed the required and sufficiently high ISEN (82% and 87%) and ISP (83% and 86%) with differences in TTI from the "norm" to "compensation" and from "compensation" to "decompensation" of asthenopia, respectively. Conclusion. The following normative indicators of asthenopia were determined: "norm" - more than 175 points; "compensation" - less than 175, but not less than 147 points; "decompensation" - less than 147 points. At the same time, these indicators do not depend on the type of accommodative asthenopia (habitual excessive stress of accommodation or asthenic form).
