Hemianopia

about-hemianopia.pngHemianopia is a term which describes a major loss to a person's field of vision where often only half of their world is seen. The main causes are Stroke, TIA's, Brain Injury and Brain Tumour.  Not everyone who suffers these conditions develop Hemianopia but some do and it is vital that there is an awareness of the condition.

Right Side Hemianopia 

This will result in the person not being able to see anything to their right hand side. The vision in both eyes will be affected, that is, the right side of the vision in the right eye and the right side of the vision in the left eye. The person may be unaware of objects or people to their right hand side as they may be impossible to see. Sometimes only the food on one side of the plate is eaten because the food on the other side is invisible. Where this happens, try spinning the plate round by 180 degrees and the remaining food may be seen. It is usually better to approach the person from their left hand side and communicate with them from this side also. Activities that occur to the person's left hand side will be seen more easily.

Left Side Hemianopia

This will result in the person not being able to see anything to their left hand side. The vision in both eyes is affected, that is, the left side of the vision in the right eye and the left of the vision in the left eye. The person may be unaware of objects or people to their left hand side as they may be impossible to see. Sometimes only food on one side of the plate is eaten because the food on the other side is invisible. Where this happens, try spinning the plate round by 180 degrees and the remaining food may be seen.
