HOTV Vision Test Compared With Tumbling E for Pediatric Vision Screening.
HOTV vision test is associated with a lower referral rate than tumbling E in preschool children.
HOTV Vision Test Compared With Tumbling E for Pediatric Vision Screening.
IMPORTANCE: Accurate assessment of uncorrected visual acuity (uncorrected visual acuity) is fundamental to pediatric vision screening.
To compare uncorrected visual acuity outcomes from HOTV and tumbling E vision tests and evaluate their suitability for pediatric vision screening.
DESIGN, SETTING, AND PARTICIPANTS: In this cross-sectional observational study, each participant underwent uncorrected visual acuity testing with both HOTV and tumbling E logMAR charts in a randomized sequence, with a 30-minute rest period between tests to minimize fatigue.
HOTV test reduced preschool children's referral rate compared to tumbling E
Overall, mean (SD) uncorrected visual acuity was 0.15 (0.22) (20/25) with HOTV and 0.20 (0.20) (20/32) with tumbling E (95% CI, -0.07 to -0.02; P < .001).
The difference between the 2 tests decreased with age, initially 1 logMAR line in children aged 3 to younger than 4 years, more than 3 letters in those younger than 8 years, and reducing to 1 or less letters by age 8 years or older.
These findings support the use of the HOTV test for children younger than 8 years. Its use could reduce unnecessary referrals, especially in the context of growing global emphasis on pediatric vision screening and early detection of myopia.
