Relumino mode may provide video terminal assistance for the amblyopic patients

This study aimed to assess whether Relumino mode TV could assist amblyopic patients using video terminals. This mode utilizes real-time image processing techniques to enhance visual effects. We recruited 38 participants with anisometropic amblyopia, all literate and cognitively capable. The Modulation Transfer Function (MTF) of the normal and Relumino modes was measured to evaluate the relationship between spatial frequency variations and visual effects. All participants underwent tests for visual acuity, reading performance (reading speed and accuracy), and viewing three 5-min videos in both modes. Afterward, they completed a Visual Function Evaluation Questionnaire. A total of 38 volunteers (mean age, 17.0 ± 13.3 years) completed this study. The results indicated that in Relumino mode, the visual scores for static images and videos with lower MTF were 5.58 ± 1.66 (p = 0.038) and 5.33 ± 1.42 (p = 0.167), respectively, suggesting better visual function with Relumino mode, compared to the normal mode. However, no significant changes were found in the LogMAR mean values for amblyopic eyes (from 0.47 ± 0.26 to 0.49 ± 0.26, p = 0.237), reading speed (from 68.62 ± 59.13 to 74.39 ± 59.78, p = 0.209) or reading accuracy (from 0.96 ± 0.12 to 0.92 ± 0.17, p = 0.019) before and after using Relumino mode. There was no significant improvement in visual functions related to text on the screen. This study suggests that the Relumino mode enhances the visual experience for amblyopic patients when watching videos or images on the TV, especially compared to the normal mode.
