What is Vision Impairment?

vision 1

Vision impairment is a term that covers many vision problems as well as different kinds of vision loss. Children with vision loss experience the world in a different way from other children. Vision impairment means lots of different things. It can range from no vision (blindness) or very low vision to not being able to see particular colours. Vision impairment can happen at any age.

What is low vision?

Low vision is when your child can’t see all the things he should be able to see for his age.

What is blindness?

A child is considered legally blind when he/she can’t see at 6 m what a child with normal vision can see at 60 m, or if her field of vision is less than 20° in diameter (a person with normal vision can see 180°). Severe vision loss (blindness) can mean that some parts of your child’s development and learning will be slower than for other children. For example, your child is slower in learning to roll over, crawl, walk, speak and be social with others, your child is slower in learning how to play, achieve cognitive milestones and use their hands effectively. Your child’s ability to do all these things should come with time and assistance.

Causes of Vision Impairment

There are multiple causes of vision impairment in children .   These include genetic conditions, damage or injury to the eye or to the pathways connecting the eye to the brain or to the visual centre of the brain.  Your baby might have vision impairment at birth. It can also happen later as a result of disease, injury or a medical condition.
The most common causes of vision impairment are:

  • neurological conditions that affect the parts of the brain that control sight (cortical vision impairment CVI)
  • cataracts
  • genetic conditions such as Albinism and retinitis pigmentosa.

If you think your child has vision problems, it’s very important to visit your doctor as soon as possible to get a diagnosis.  The GP will probably send you to a Paediatric Ophthalmologist. The Ophthalmologist will be able to examine your child and do tests to work out what the problem is.
