It is difficult to predict the progress and the speed of the deterioration. Sometimes these will remain quite stable and at other times the deterioration seems to go faster. The deterioration of hearing does not have to run parallel with the deterioration of eyesight.
Sometimes you may have a feeling that the eyesight strongly deteriorates because you increasingly miss information and lose sight of the overall picture. Still, a field of vision test may show little deterioration in this situation. Often measurements make clear that not the loss of eyesight but the loss of hearing has increased. Hearing less well you can give you the feeling that your eyesight has deteriorated.
As vision gets poorer, a greater demand is made on hearing. Think for instance of hearing direction, distance and warning or signalling sounds. All this information is no longer seen and therefore they are to be compensated by the hearing. A new and better setting of hearing aids or CIs can often ‘improve’ the feeling for orientation.
It is of major importance that both hearing and eyesight are properly supported by a professional who looks at both senses and tries to improve these simultaneously. This can be done by means of adjustments and rehabilitation. Orientation training and/or a mobility training is of little use with incorrectly set hearing aids. Computer training using voice support and/or voice-over is only useful if hearing aids and/or CIs have been correctly set.
