Diane: Difficulties with visual complexity.  This is a huge area for our students with cortical visual impairment functioning in phase 1.  Remember that there's three components to visual complexity.  Complexity of the target itself. This is a very low target with low complexity, it's just a single color.  Complexity in an array. When there's lots of things scattered about, it's a complex array.  If there is just one target for the student to look at, you've reduced complexity in the array. And complexity in the sensory environment.  This would include auditory interference, tactile interference, lots of visual stimulation going on. 

You want to make the sensory environment as plain as possible, particularly for a student functioning in phase 1.  Remember to turn off cell phones.  Turn off the TV, the radio.  Stop talking.  No pats on the shoulder, or arm, or back.  And no other auditory input when you want the child to use their visual learning channel. 

One of the techniques that I found that works really well with some of our students functioning in phase 1 that are not ambulatory, they're not able to move from their bed, and they're kind of stuck in a situation that maybe there's lots of light streaming through the window, there's lots of activity and movement of people walking around them, is to use what I've called a "CVI den."  You take a very inexpensive children's pop-up tent that is bottomless, and you line that pop-up tent with black headliner fabric.  The headliner fabric is compatible to Velcro and toys that you attach with Velcro.  And you can stick the toys or the lights onto the fabric on the inside of this pop-up tent.  It's very user-friendly for a teacher that is on the move, an itinerant vision teacher, because it folds down very easily as well.  It can be placed over the child, and I’ve literally gotten in the tent with the child, and we've done some activities as I’ve been inside the tent with the child in this situation.  And I call it a CVI den.
