Abstract
Objective. To develop a new method of investigating visual acuity based on preferential looking using eye tracker. Materials and methods. We investigate data of 75 participants (150 eyes) with visual acuity from 0.01 to 0.1 and from 0.2 to 1.0. The study was done monocularly. While using the developed preferential looking method Landolt rings changing the size and position of gap were shown on monitor screen as a stimulating object. Infrared oculography system documents objectively and reproducibly whether or not stimulus is seen by participant. Then we compare the results of visual acuity obtained using developed method with data received with wall chart. Results of the study. The results obtained with preferential looking method were compared with subjective measurements of visual acuity and significant correlation of values was obtained. Conclusion. The high diagnostic value of developed method in clinical and expert practice was proved in visual acuity measurements above 0,2. Visual acuity measurement based on preferential looking can be used in clinical and expert ophthalmological practice as an additional control method (4 figs, bibliography: 15 refs).
