Efficacy of predictive holistic indicator for prevention of damage to visual health

Throughout the years, more factors have been added to the visual affectation, with environmental, economic, and cultural factors considering the principle ones. Therefore, the importance of this study, with a systemic focus, is to apply a predictive holistic indicator based on the factor that affect visual health in patients of the Optometry Clinic, Interdisciplinary Health Sciences Center (CICS), Santo Tomás Unit (UST), of the Instituto Politécnico Nacional (IPN), México, with a universe of 50 patients who attended a first evaluation at which tests were carried out of visual acuity, Schirmer II test, and biomicroscopy; also, we gathered information through the application of a questionnaire designed to generate the prediction of the visual-health factor of each factor. From the latter, we obtained a holistic index of 50.90% as visual-health prognosis, which fell within a range of fair; later, at 6 months, we performed a second optometric evaluation to find the relationship between the number of patients categorized in each of the visual-health indicators and by gender during the first and second clinical evaluation, finally, we carried out the statistical significance test by means of a p value [p₁-p₂] in terms of Z_α-0.05, in which we found, in both genders and in the different visual indicators, a lesser p value with respect to Z_α-0.05. This indicates that there was no statistical significance; thus, we can conclude that the predictive holistic indicator is functionally given that its prognosis was fulfilled.
