Visual Rehabilitation After Occipital Stroke

A computer software and chin-rest necessary to perform visual training will be loaned to each subject to be used at home. They will perform one to two daily training sessions in their home, consisting of 200-300 trials each. The visual task performed repetitively will involve discriminating the direction of motion of a small cloud of dots located at a predetermined location in the intact field. The computer program will automatically create a record of patient performance during each home training session. Subjects will train daily (about 40-60 minutes total), 5 to 7 days per week for at least one and up to 6 months.

After the initial training period of one to six months, the same computer software will continue to be used for all subjects. The visual task performed repetitively will involve discriminating the direction of motion of a small cloud of dots located at a predetermined location in the blind field. The computer program will automatically create a record of patient performance during each home training session. Subjects will train daily (about 40-60 minutes total), 5 to 7 days per week for at least 6 months.
