Individuals with homonymous hemianopia (HH) sometimes report being told to simply move their heads more to improve their efficiency with reading or mobility tasks.With such instruction alone, individuals who are aware of their deficit tend to adapt disorganized scan paths, often scanning excessively into their blind field and putting themselves at risk for missing obstacles in their intact . A fundus controlled study. Saccadic training purposes to train these movements to improve the accuracy of saccades, search strategies, reading speed and scene registration.

Improving the patients ability to accurately perform both larger and more accurate saccadic eye movements to the side of the loss can improve the patient's functioning in mobility and activities of daily living. These patients have a natural expanded visual field from the eye drifting out and thus may not require further optical field expansion. Diminished vision or full vision loss in the left or right half of the visual field of one or both eyes.

Symptoms of homonymous hemianopia range from mild to severe and include: Heteronymous hemianopia symptoms are less severe and usually only cause depth perception and peripheral vision problems. This shifts the existing visual field to that side and allows the patient to then detect objects in the remaining visual field and make smaller accurate saccades to the exact object. [Emphasize the importance of study on treatment and visual restoration related to impairment of retro-chiasmal visual pathway]. The prisms neither improve reading speed nor allow patients to resume driving. Strategies to improve reading ability: Use a straight edge to direct the eyes to the next line of text. With a stroke, the eyes are functioning normally and it is the brain that is not processing the images from one part of your visual field.

Training Hemianoptic Reading Skills: Training of saccadic eye movements may help improve reading, however, often more specific therapies and strategies are required particularly in patients with right homonymous hemianopsia. Create a treatment plan and coordinate services with vision rehabilitation treatment team. The loss of the visual field alone does not fully explain the problems in saccadic eye movements. Hemianopia Activity-Based InTervention (HABIT): refining and operationalising a rehabilitation intervention for visual field loss after stroke University of Bristol Hemianopia Activity-Based InTervention (HABIT): refining and operationalising a rehabilitation intervention for visual field loss after stroke Beau B, et al.(2014).
