Assessing pediatric visual acuity with a computerized optokinetic nystagmus analyzer
Objectives
To investigate the practicality, accuracy, and consistency of a computer-based Optokinetic Nystagmus (OKN) analyzer for vision diagnosis in preschoolers.
Design
A comparative study evaluating the performance of a computerized OKN analyzer against the traditional E-word visual acuity chart in assessing visual acuity in preschool children.
Participants
A total of 138 children aged 2 to 6 years were enrolled in the study, divided into five age groups: 2 years (29 children), 3 years (27 children), 4 years (28 children), 5 years (28 children), and 6 years (26 children).
Methods
Visual acuity was tested using both the nystagmus meter and the E-word visual acuity chart. Statistical analyses, including correlation coefficient calculation and chi-square tests, were conducted to evaluate the testability and consistency of the methods.
Results
Out of 138 participants, 125 (90.6 %) successfully completed the test using the computerized OKN analyzer. There was no significant difference in the measurability across different age groups. The testability of the E-word visual acuity chart was significantly lower at 71.0 %. A strong correlation (R = 0.872) was found between the results from the nystagmus meter and the E-word visual acuity chart, indicating high consistency between the two methods.
Conclusion
The computerized OKN analyzer is a reliable, accurate, and practical tool for assessing visual acuity in preschoolers. It offers a non-invasive alternative to traditional methods, with high testability and strong correlation with standard visual acuity tests, making it a valuable tool for early detection of vision impairments in young children.
