figure/ground defects in which a patient can see either the background but not the object residing somewhere in the whole scene, or conversely can see the object but sees no background around it (simultanagnosia)
a patient, while attempting to put one foot into a slipper by trying to insert the foot into a nonexistent slipper several inches from the real slipper, even as the patient focuses on the actual slipper (optic ataxia)
a patient raising a fork or spoon containing food to a point on the patients face above or below the mouth, and possibly finding the mouth by trial and error by manually moving the utensil on the face (optic ataxia)

Treatment
In terms of the specific rehabilitation of visuoperceptual disorders such as Bálints syndrome, the literature is extremely sparse. According to one study, rehabilitation training should focus on the improvement of visual scanning, the development of visually guided manual movements, and the improvement of the integration of visual elements. Very few treatment strategies have been proposed, and some of those have been criticized as being poorly developed and evaluated.Three approaches to rehabilitation of perceptual deficits, such as those seen in Bálints syndrome, have been identified:

The adaptive (functional) approach, which involves functional tasks utilising the persons strengths and abilities, helping them to compensate for problems or altering the environment to lessen their disabilities. This is the most popular approach. The remedial approach, which involves restoration of the damaged CNS by training in the perceptual skills, which may be generalised across all activities of daily living.
Optic ataxia
Optic ataxia is the inability to guide the hand toward an object using visual information where the inability cannot be explained by motor, somatosensory, visual field deficits or acuity deficits. Optic ataxia is seen in Bálints syndrome where it is characterized by an impaired visual control of the direction of arm-reaching to a visual target, accompanied by defective hand orientation and grip formation. It is considered a specific visuomotor disorder, independent of visual space misperception.Optic ataxia is also known as misreaching or dysmetria (English: difficult to measure), secondary to visual perceptual deficits. A patient with Bálints syndrome likely has defective hand movements under visual guidance, despite normal limb strength. The patient is unable to grab an object while looking at the object, due to a discoordination of eye and hand movement. It is especially true with their contralesional hand.Dysmetria refers to a lack of coordination of movement, typified by the undershoot or overshoot of intended position with the hand, arm, leg, or eye. It is sometimes described as an inability to judge distance or scale. As Bálint states, optic ataxia impaired his patients daily activities, since, while cutting a slice of meat...which he held with a fork in his left hand, ...would search for it outside the plate with the knife in his right hand, or ...while lighting a cigarette he often lit the middle and not the end. Bálint pointed out the systematic nature of this disorder, which was evident in the patients behaviour when searching in space.
