Narrator:

Six-year-old Emma never looked at the world the way most children do. Her mother realized something was wrong when she was about six months old.

Amy Weaver:

She looked blind to me. She wasn't looking at anything. She would stare at lights. She would really hold that stare, but never make eye contact with me.

Narrator:

Doctor after doctor offered little hope and no diagnosis. Eventually Doctor Christine Roman Lantzy (LANT-zee) was able to put a name on it… Cortical Visual Impairment.

Christine Roman Lantzy, Ph.D.:

Cortical visual impairment is damage to the visual processing centers and the visual pathways in the brain, the areas that regulate vision in the brain.

Narrator:

Having C-V-I means Emma's eyes work, but her brain can't sort out what she sees.

Christine Roman Lantzy, Ph.D.:

So they see the world as more or less a gigantic hidden pictures image in which there's all kinds of jumbled information.

Narrator:

The treatment for C-V-I is not medical, it's educational.

Christine Roman Lantzy, Ph.D.:

Because the only way the child can actually improve their vision is through the eyes. So the more they look, the more they can look.

Narrator:

To motivate them to look, teachers use exercises with toys that emphasize simplicity, light, color, and movement.

Christine Roman Lantzy, Ph.D.:

And the more they look, the more wiring neuronal firing, the more development in the brain for vision.

Narrator:

Most children can improve to normal or near normal vision.

Amy Weaver:

We've come a long way. I mean she used to just sit and stare and now she interacts. We're not you know, 100% there. She has other issues, but you know, she's doing well.

Narrator:

Now Emma 'sees' more effectively. For WebMD, I'm Damon Meharg.
