Abstract
Abstract Accommodation training apparatus is modified to include electroencephalography apparatus for monitoring the patient's brainwaves. This permits a patient to be trained to enter, and to remain in, the alpha state, even with the eyes open and with something to look at. A two-dimensional CCD matrix is used to receive reflected-back radiation from the eye. A computer is connected to the matrix and permits the patient to be trained for correction of conditions such as strabismus, nystagmus and eccentric fixation by identifying whether the patient's eye is moving or whether the patient's state of accommodation is changing. An LCD matrix is used to present variable visual information to the patient's eye. This facilitates training the patient for dichotic learning. Advantageously, electromyography apparatus is used to monitor the tension of one of the patient's muscles, advantageously the frontalis muscle.
