Q: My three months old daughter had three loops of cord around the neck when she was born. Her sugar level was very low and she got infection too. Her parietal lobes and occipital lobes of brain are injured since birth. She has not yet started fixing her eyes. She follows the light of mobile phone and also has perception of sunlight but doesn't follow any object or toy and neither looks towards our faces. How much time it will take for her vision to develop?

A:Your child has visual impairment because of damage to the visual areas of the brain. This is called Cortical Visual Impairment. It is obvious that she can perceive light. Higher functions like perception of colours, shape, depth, motion etc. will take time - there is no time table. The other parts of the brain concerned with vision will take over some functions of the damaged areas resulting in improving vision. There are high chances that complete vision will not be restored.
