Clinical study on the application of digital and visual retinoscope in the detection of ametropia in adolescents

Abstract

AIM: To study the application value of digital and visual retinoscope in the detection of ametropia in adolescents.METHODS:A retrospective analysis of digital visual inspection and traditional retinography test results of 69 adolescents in the ophthalmology department of our hospital from January 2019 to October 2019. SPSS 20.0 software analyzed the correlation of spherical equivalent, diopter of cylindrical power and axial direction measured by two detection methods. Taking the clinical examination results as the control, the diagnostic value was compared. RESULTS: There was no statistically significant difference in the measuring of spherical equivalent, diopter of cylindrical power and axial direction between digital and visual retinoscope and traditional retinography(t=0.081, 1.778, 0.983, P=0.935, 0.077, 0.327). And there was a significant positive correlation(r=0.745, 0.572, 0.941, P<0.01). At the same time, two detection methods have the same sensitivity. Digital and visual retinoscope higher than traditional retinography at the specificity, accuracy, positive predictivevalue and negative predictive value.CONCLUSION: The detection of ametropia in adolescents with digital and visual retinoscope has a good correlation with traditional retinography. Compared with the latter, the former has improved for the diagnosis of ametropia, which deserves clinical attention.
