Objectives

Narrative objectives1

Children's visual acuity develops by the age of eight, but refractive error or eye disease before that age can impede visual development and result in amblyopia. Many cases of amblyopia can be treated with early detection, but late detection can lead to lifelong visual impairment. Early detection of amblyopia is therefore important. However, measuring visual acuity in infants and toddlers is difficult because infants and toddlers do not understand visual acuity tests using Landolt rings, which are performed on adults.
Since infants have a tendency to prefer to look at indicators that have a pattern, the preferential looking (PL) method is used to measure visual acuity using this property.
The PL method requires the examiner's skill to measure visual acuity by observing the infant's gaze, which is not available in many facilities, and also relies on the examiner's subjective judgment. Therefore, infants often cannot be screened and are left for observation, delaying the detection of amblyopia.
If the PL method, which can only be performed at a limited number of facilities, could be mechanized to allow for more widespread and more easily administered, it could lead to the early detection of amblyopia.
Therefore, the purpose of this study is to analyze the visual acuity measurement by the Teller Acuity Card (TAC), which is often used clinically among the PL methods, using a mechanical algorithm, and to verify whether the test results can be similar to those obtained by the current TAC method.

Other related information

This will be conducted as a prospective study.
Subjects will be patients who visited Nagoya University Hospital between September 15, 2024 and March 31, 2029, and will undergo two types of visual acuity tests.
One is the examiner's conventional preferred looking (PL) method, which is the usual method of vision testing for infants, and the other is the mechanized PL method.
Mechanical PL is being developed in this research, and it mechanizes the examiner's PL method by using an eye-tracking device to capture eye movements toward the indicators displayed on the screen.
The obtained measurement results, age, gender, and other data will be recorded and statistically analyzed. Statistical methods such as Accuracy/ Precision/ Recall and ROC curves will be used to evaluate the accuracy of the mechanical PL method compared to the conventional PL method.
