Titel | Strabismus and hemianopia |
Doel | Homonymous hemianopia leads to a severe disturbance of visual orientation under binocular conditions. In contrast patients with bitemporal hemianopia binocularity show a normal visual orientation except a hemifield-slide phenomenon is present. |
Methodes | Visual field defects and strabismus can prove to be a difficult combination. In some cases binocular visual fields can possibly be enlarged or reduced by the squint. A simulation of different visual field defects will show the effects of strabismus (eso-, exotropia). The simulation will also show the effect of eye muscle surgery in these cases. |
Resultaten | Although expecting that a visual field loss and an additional strabismus will lead to a more pronounced disturbance of vision, rarely a strabismus may even compensate the visual field defect. In these cases strabismus surgery is not recommendable. |
Conclusie | Before a strabotomy it is necessary to know if there is a visual field defect. |
