Physical Effects of Stroke Vision Loss Vision loss is generally referred to as visual field loss, which means that a person has a disturbance in the visual field, which can no longer be seen. To classify visual field loss, the extent and extent of the visual disturbance are taken into account. A stroke that occurs in the left hemisphere will affect the right visual field of each eye. The same is true for the right hemisphere which influences vision in the left visual field of each eye. Types of vision loss • Hemianopsia: blindness in half of the visual field. The most common form is homonymous hemianopia, which means the vision loss is on the same side of each eye. Approximately 8-10% of stroke survivors suffer from homonymous hemianopia. • Quadrantanopia: blindness in one quarter of the visual field. • Scotoma: Blindness in a localized area much like a blind spot where there shouldn't be one. • Tunnel vision: blindness in which peripheral vision is lost, a phenomenon known as bitemporal hemianopia. Bitemporal hemianopia causes a loss of the temporal half of the visual field in each eye. Treatment of vision loss Treatment strategies aim to increase the field of vision, this treatment is divided into three categories: Optical therapy: or rather shifting the field of vision, involved using mirrors or prisms to move images from the affected area to the unaffected interested. This therapy does not restore the affected areas but rather can increase the field of vision by up to 20 degrees. Saccade training: a treatment that increases eye movement. As a person scans and landscapes there may be a blind spot due to vision loss. The therapy can help train the eye muscles to compensate for remaining within the unaltered field of vision so that the head has to turn. Visual Restoration Therapy:...... middle of paper ...... reflexes Treatment of Spasticity In the treatment of spasticity there are specific goals to: increase range of motion, relax stiff muscles, and inhibit involuntary contractions; To achieve these goals, specific drugs and therapies are prescribed.
