What is congenital blindness?
If a child who is unable to see or with severe visual impairment is born, it is reported to have congenital blindness. Many different conditions can cause congenital blindness, including certain diseases and genetic factors. The term "congenital" simply means that it is present from birth, and does not provide information that a child can be born blind. Sticking may sometimes also occur with other conditions such as autistic spectrum disorders and mental retardation.
There are many things that can cause a person to be born with innate blindness. One of them is a physical defect in the eyes or abnormality in the brain. Some people are born blind because of the infections that their mothers developed when they were pregnant. For example, German measles, viral diseases can affect the development of children and cause innate blindness. Others may be born blind due to inherited state or injury that occurs during childbirth.
One cause of congenital blinudness is a leber congenital amaurosis (LCA), rareDegenerative diseases in which retina do not work properly. Retinopathy of prematureness, a condition in which the retina of the child born did not have time for proper development, can cause blindness in serious cases. It is also possible for the child to be born with congenital cataracts, which means that the lens of the eye is cloudy, causing loss of vision.
When children have congenital blindness, their learning and development needs differ. With the exception of any other conditions, they can learn and develop in almost the same way as other children, but they may need the help of special teachers or materials to help them without normal sight. There are many teaching and development programs that emphasize by touch, hearing and even taste and smell.
Finally, the feeling of touch plays a very important roller learning. Blind children and adults can read books even if they don't see them. This includes a feeling of small bumps or teček that represents letters and words, reading hands instead of eyes.
hearing a blind person can also play a decisive role in his ability to learn and read. There are devices designed to read information on a written page and allow blind people to listen to books and written materials rather than using Braillo. In fact, some of these facilities allow blind children to attend a regular school if they want it.
The idea of birth without supervision or with a significantly impaired vision may seem scary for the observed individuals. It may be difficult to imagine how a blind individual can perform daily tasks that most people take for granted, such as walking or running errands. One of the sources that a blind person can have is a guide dog. These dogs are specially trained to help visually affected people move the set and even the streets safely.
