Mr. Kanehari Nakamura of Kishiwada Rehabilitation Hospital, Ken Fuchigami, visiting researcher, and Professor Shu Morioka of Kio University reported on the effectiveness of eye movement training for binocular diplopia.

 It has been reported that approximately 90% of patients develop eye movement disorders, including binocular diplopia, after traumatic brain injury. Binocular diplopia is caused by a misalignment of the visual axes of the left and right eyeballs, causing one object to be perceived as two objects, increasing the possibility of fractures due to falls and interference with daily activities and activities. have a negative impact on the recovery of quality of life (QOL).

 In this study, we performed eye movement training on a male patient in his 30s who presented with decreased motor function in the abduction direction of the right eyeball and binocular diplopia after a traumatic brain injury, and tracked the progress of treatment. Eye movement training was performed twice daily for 2 minutes and continued for 40 weeks. The subjects included following a laser pointer that moved slowly or quickly to the right, moving and holding the right eyeball in the maximum direction of abduction, and following a blinking target.

 The treatment effect was evaluated based on the movement distance of the right eyeball in the abduction direction, the angle of appearance of diplopia from the midline of the right eyeball, gaze transition, and error in gaze coordinates. The right eyeball abduction distance increased after the intervention compared to before the intervention, indicating an improvement. The angle of appearance of diplopia also increased after the intervention, indicating that diplopia was less likely to appear. Furthermore, in the gaze transition evaluation, it was confirmed that the variation in gaze transitions decreased over time.

 The above results showed that eye movement training improved the impaired right eyeball abduction movement and diplopia, and stabilized the line of sight. On the other hand, after 4 weeks of intervention, the error in gaze coordinates was larger on the contralateral side than on the affected side, suggesting the need for eye movement training not only on the affected side but also on the non-impaired side. .

 In the future, they plan to increase the number of cases and verify the effectiveness of eye movement training for binocular diplopia.
