About 70-80% of activities in class, such as reading, copying information from blackboards, playing ball games, require effective extra-ocular control, so do most daily activities, like crossing roads, dressing and playing chess. In fact, the vestibular system and the visual system are closely integrated in neurology. Any dysfunction of the vestibular system could lead to poor functional use of extra-ocular muscles. Normally speaking, at the age of five, children could perform eye-tracking quite well when the position of their head is stabilised.
Signs of postural-ocular motor disorder exhibited after five include:
- Difficulties in reading
- Difficulties in copying information
- Being week in ball games
- Poor self-care performance
A seminar will be held in November 2013 by the occupational therapist of Heep Hong Society to help parents understand the importance of extra-ocular control and corresponding training strategies. For details, please refer to the Chinese version.
