Although every one of our senses plays a role in early development, vision and hearing certainly seem to lead the way. Much of early parent/child bonding has to do with the child's ability to make eye contact and sustain a gaze with his parents, respond to their voices by gurgling and cooing, and to be comforted by the sight and sound of them. Much of the reason an infant tries to move is because he sees or hears something that intrigues him. He learns that things and people exist in the world primarily because he sees and hears them come and go. He visually tracks an object he pitches to the ground or hears it hit the floor. That tells him the object still exists, even though it is not in his hands any longer. When she cries she can hear Daddy calling to her or see Momma walk into the room. She can inspire her parents to linger and play with her by cooing and making eye contact, the earliest form of conversation. He learns about size, shape, color, functions of objects, social interactions, and so much more just by listening and looking at the world at work. Early development has critical links to a child having full use of his/her vision and hearing. When these senses don't work perfectly or not very well, everything is impacted.
Professionals working with infants and families may have a hard time suggesting that there is a problem with a child's vision or hearing. This is especially true when the family is already dealing with their child's other medical or disability issues. After all, a family can only deal with so much at one time. Because infants are much harder to test for vision and hearing loss, many mild impairments (or sometimes even major impairments) may not be diagnosed quickly. Subjecting the family to another round of testing is always a hard call.
As we said earlier, much of the sensory information that is vital to children's development comes through the senses of vision and hearing. During the first three years of a child's life major neural networks are being formed in the brain. Much of this development comes from distance senses, i.e., vision and hearing, which allows us to know about things and people in the world even when we are not in physical contact with them. After the first three years, development of these neural networks becomes slower. Skills that may be gained in early intervention cannot be made as quickly when the child is older.
For these and other reasons, children should be regularly checked for vision and hearing problems. We know that even mild problems with these senses can have major impact on learning. A mild hearing loss in a noisy home or daycare center can result in a child who misses critical bits of information. He may miss sounds that let him develop normal language and speech patterns. He may miss instructions his parents or babysitter gave him and appear to be misbehaving. He may become withdrawn because he is not sure what is expected of him. If he has a visual field loss he may constantly be stumbling over things. This has great impact on self-concept. A child who is sensitive to light may not enjoy or feel secure playing out of doors.
Every child, with or without a disability, should have regular and periodic vision and hearing checks. If the child is severely disabled, this can be even more important since their other senses may not be as useful in compensating for what they miss visually and auditorially. In fact, this is so important that schools complete vision and hearing screenings at regular intervals throughout the remainder of the child's educational career. These types of screenings are even more critical from birth to age three.
Parents know more about their child than anyone else does. Often we meet parents who tell us that they knew something was wrong with their child's vision and hearing before any of the doctors mentioned it. In fact, many have been told that they shouldn't go looking for trouble or that their child would "grow out of it."
Parents should trust themselves when they feel there is something wrong with the way their baby uses his vision or hearing. They should feel comfortable insisting that vision and hearing are tested, especially if their child is at high risk for vision and hearing loss.
There are many red flags associated with vision and hearing loss. Below are the syndromes, diseases and conditions, listed on the Texas Deafblind Census, that put a child at high risk for deafblindness. Children with these etiologies should be watched closely for vision and hearing problems.
Sometimes the child's etiology is unknown or the child may have only one diagnosed sensory loss. Professionals working with infants and young babies, as well as parents, should be aware of the red flags that may indicate a problem with either vision or hearing.

If there is a concern about vision or hearing, your ECI program should make a referral to the appropriate medical professional. We would like to encourage ECI personnel to work closely with their Teacher of the Visually Impaired, Teacher of the Deaf and Hearing Impaired, and/or TCB Children's Caseworkers in helping the families prepare for the doctor visits. These professionals have much to offer to the process. They can usually share the names of doctors, audiologists, and vision specialists who have more experience working with disabled children. Often they can guide the ECI professional and parents in compiling a list of concerns related to the way the child uses his vision and hearing. More importantly, they can provide parents with information about the types of testing that may be done and how to help prepare the child for testing. This level of support can be provided before an actual vision or hearing referral has been made.
Parents and professionals must keep a close watch on a child's progress related to vision and hearing. Hearing and vision issues must not be ignored, especially if the child has other disabilities. When a problem is suspected, no time should be lost in following up on the concern. We owe it to our children not to lose that critical window of time between birth and age three. When early intervention can make such major differences in life-long functioning, they can't afford to wait.
