ABSTRACT

Purpose: Visual acuity screening in children during and after the Covid-19 pandemic by recommending parents a free and easy Ocular Check Application. Methods: Visual acuity (VA) test were conducted for 86 eyes of 43 subjects between the age of 5 to 13 years, using both gold standard chart and Ocular Check application. The participants had gone through ocular screening to avoid amblyopia, strabismus or any ocular pathology. Many tests for screening were done like external eye exam, cover and uncover, light reflex, and ocular alignment examinations. Results: The median VA logMAR of all eyes tested using Standard and Ocular Check application were 0.0 LogMar. Intraclass Correlation Coefficient (ICC) showed a strong positive correlation between the two charts (ICC=0.857; P<0.001) in total number of eyes. In addition, a strong positive correlation was also found between the two charts for each eye (OD: ICC=0.845; P<0.001, OS: ICC=0.87; P<0.001). Conclusion: VA measurements with Ocular Check application corresponded well to the standard chart, suggesting potential utility of alternative portable VA tests for in-office or remote vision monitoring, particularly during the curfew time in pandemic situation of Covid 19.
