WMBD/WYZZ— Normal— Attention Deficit Dsorder or a vision problem? The symptoms overlap, but are commonly misdiagnosed.  Children with attention problems are three times more likely to have vision problems, so that ADD diagnosis sometimes has more to do with sight rather than behavior.

"I couldn't see the board, I couldn't focus very well, I just kind of gave up," 10-year-old Kacie Haag said.

Kacie Haag suffers from Convergence Insufficiency. She has a hard time seeing things close up without crossing her eyes.

"If I look at a paragraph, I could only see the spaces," Kacie said. 

At first, Kacie’s family doctor diagnosed her with Attention Deficit Disorder, or ADD.  Two years later, Kacie met Dr. Terri Rieger who properly diagnosed her with a vision problem.  After eight weeks of vision therapy, Kacie was completely off of her ADD medication, which came with negative side affects. 

"I couldn't eat very well, I wasn't hungry,” Kacie said.

"A lot of times they're amphetamine-based medications which have dangerous side affects to them, it's a concern to a lot of parents when they're recommended," Dr. Reiger said.

Kacie's mom says now she enjoys going to school and reading.

"She's so much faster, so much more fluent overall,” Trisha Haag said. “I thought, this has got to be so much easier for her, I wish I had done this years ago."

Dr. Rieger says it is important to get your children's vision tested so they are properly diagnosed. She says two-thirds of US children do no seek vision services before their sixth birthday.
