Gottlieb Visual Field Awareness System
 |
The Gottlieb Visual Field Awareness System allows many persons who have suffered visual field loss due to a neurological insult, improved function, awareness, and orientation. It is usaed most frequently in the treatment homonymous hemianopsia, a loss of one half of the visual field in each eye. It is also helpful in other types of visual field loss. | |
 |
Those persons who may have previously been told that they will learn to live with their visual field loss in time, now have available to them an effective clinical method of treatment. | |
 |
For those with more recent visual field loss, the system can hasten the rehabilitation process through the re-establishment of proper spatial perceptions and perceptual judgments. It can also assist these persons to move back into the mainstream of their personal, vocational, and avocational involvements. | |
|
|
Gottlieb's novel approach was to abandon the traditional equal prism in each side in a straight line and rather place a small wafer of base out prism in a round shape on the side of the visual field loss. | |
 |
The idea is to shift the image into the patient's still functional field as the patient makes natural scanning movements. | |
 |
The unique prescription helps patients scan into the area of visual field loss, to see things more clearly, sooner, and to demonstrate increased speed and accuracy of perceptual processing. The prism is used for orientation, spotting, and localization. | |
 |
The patient does not look through the prism while walking, but uses it selectively for finding objects and localizing position in space. | |

|
The Gottlieb Visual Field Awareness System is mounted on the side of the vision loss in only one lens and mounted just outside the colored portion of the eye. | |
 |
When the eye on the side of the hemianopsia has verey poor visual acuity, the Gottlieb VFAS can be mounted on the nasal side of the other eye. | |

The Gottlieb Visual Field Awareness System
has greatly improved our success rates in aiding patients after hemianopic
visual field loss. Previous methods used press-on prism
