OBJECTIVE: To compare the results and performance of the Lea and HOTV charts in determining the visual acuity of preschool children.


DESIGN: This is a prospective cross-sectional study comparing two visual assessment tools.


SETTING: The study was conducted at Barangay Ugong Health Center, Pasig City, Philippines.


PATIENTS/PARTICIPANTS: Information dissemination was conducted at the Sikapin Day Care Center, Barangay Ugong Day Care Center and the Barangay Ugong Health Center. A total 117 children aged 3-5 years old who were given consent by their parents were included in the study.


MAIN OUTCOME MEASURES: To compare the Lea and HOTV charts in terms of its testability, time to complete the test, number of children unable to complete the test and visual acuity results.


RESULTS: Overall, more than 95% were able to complete the binocular pretest for the HOTV and Lea. However, there was no significant difference between the two charts (p=0.518). Children's ability to complete the pretest increased slightly with age. Time to complete the test and the number of children unable to complete the test were also similar. Using the paired t-test in analyzing the visual acuity results, it showed that HOTV testing had a better visual acuity result compared to Lea. Overall agreement between the two tests result for visual acuity was 98.92%. CONCLUSION: Overall, HOTV and Lea charts are applicable in 3-5 year old children. The results of this study showed that there were no significant difference between the testability, time to complete the test and number of children unable to complete the test. However, HOTV showed better visual acuity results compared to the Lea chart.
