How do innovative occluding glasses compare with handheld spoon shaped occluders in children's visual acuity test? A diagnostic agreement study

A study compared two types of eye occluders during visual acuity testing in 200 children aged 3-9 years at a Chinese university hospital. Children were divided into two groups, with one group first tested using traditional spoon-shaped holders followed by novel occluding glasses, and the other group in reverse order. Results showed excellent agreement between both methods with a correlation coefficient of 0.989 for both eyes and mean score differences of 0.007 for the right eye and 0.005 for the left eye. Among children, the occluding glasses were more attractive (61% of children), however, traditional holders were preferred in terms of comfort and ease of use (90-93% of children). The study confirms that occluding glasses are a promising tool for visual acuity testing in young children, although further refinement is needed.
