Colour vision testing in pre-school-aged children

Insights
This study evaluated color vision tests for children aged 2-6 years. The Lanthony Tritan Album and Ishihara test showed better performance in older children compared to the Velhagen test.
Area of Science:
- Ophthalmology
- Pediatric Vision
- Color Vision Testing
Background:
- Assessing color vision in young children is crucial for early detection of visual impairments.
- Standardized color vision tests often present challenges in interpretation for pre-school aged children.
- Evaluating the efficacy of different pseudo-isochromatic plate tests in pediatric populations is essential.
Purpose of the Study:
- To compare the performance of three different pseudo-isochromatic plate tests in children aged 2 to 6 years.
- To determine the age-appropriateness and interpretability of the Velhagen Pflügertrident test, Lanthony Tritan Album, and Ishihara test.
- To identify potential difficulties encountered by young children when using these color vision tests.
Main Methods:
- A cohort of 84 children aged 2 to 6 years participated in the study.
- Children were administered three distinct pseudo-isochromatic plate tests: Velhagen Pflügertrident test, Lanthony Tritan Album, and Ishihara test.
- Performance was evaluated based on correct interpretation rates for each test and age group.
Main Results:
- None of the 2-year-old children could comprehend any of the tests.
- The Velhagen test was correctly interpreted by 20% of 3-year-olds, increasing with age.
- The Lanthony Tritan Album and Ishihara test demonstrated higher performance rates in 3- and 4-year-olds compared to the Velhagen test, with 6- and 5-year-olds performing well on all tests.
Conclusions:
- Pseudo-isochromatic plate tests are not suitable for children under 3 years of age.
- The Lanthony Tritan Album and Ishihara test are more appropriate for assessing color vision in children aged 3-6 years compared to the Velhagen test.
- Specific plate designs, such as winding lines in Ishihara plates 30 and 32, may pose challenges for younger children and require adjusted interpretation criteria.
Abstract:
84 children aged from 2 to 6 years were tested with three different pseudo-isochromatic plates: Velhagen Pflügertrident test, Lanthony Tritan Album and Ishihara test. The Velhagen test was correctly interpreted by all of the 6- and 5-year olds, by 80% of the 4-year olds and by 20% of the 3-year olds. The Lanthony Tritan Album was well performed by all of the 6-, 5- and 4-year olds, and by 80% of the 3-year olds. The Ishihara test was acceptably performed by all of the 6- and 5-year olds, by 90% of the 4-year olds and by 40% of the 3-year olds. None of the 2-year olds could understand any of these tests. In the Ishihara test, the winding lines in the plates No. 30 and 32 were difficult for children; the incomplete interpreting of them must be accepted for a correct answer.
