Cerebral visual impairment

Indicators of cerebral visual impairment include:

• Crowding i.e. difficulty differentiating between background and foreground visual information (e.g. can’t see items if they are on a patterned table cloth).

• Problems with fast eye movements.

• Problems with detection of movement.

• Problems with depth analysis.

• Visual field defect – peripheral vision easier than central vision.

• Vision appears to be variable, changing with circumstances.

• Vision may be better when either the object or the person is moving.

• Close viewing is common, to magnify the object or reduce crowding.

• Substantial impairment in function and making sense of what is seen.

• Often able to see better when told what to look for ahead of time.

• Colour vision is well developed, and visual acuity normal or sub-normal.

• Typically, paid carers inadvertently attribute the problems to poor attention or motivation.

• There are several causes, including cerebral palsy.

• If suspected, consider referral to ophthalmology or RNIB, Vision Assessment worker:
