[Homonymous hemianopsia]

Abstract

Anatomical principles of the suprachiasmatic pathway. The neuro-ophthalmological examination of homonymous hemianopia: qualitative perimetry (confrontation tests), quantitative perimetry (campimetry on the Bjerrum screen, kinetic perimetry, static perimetry, automatic computer controlled perimetry, perimetry with colours, flickerfusion frequency-perimetry), oculomotor disturbances (gaze strategies, opto-kinetic nystagmus), pupillary disturbances, visual evoked potentials, anosognosia, Riddoch-phenomenom, hemiachromatopsia. Synopsis of different forms of homonymous hemianopsia: Unilateral, total or quadrant, bilateral, temporal half moon preserved or not, homonymous scotomas, horizontal hemianopsia. Pathogenetic analysis: tumors, infarcts, cerebral injuries, neuro-surgical operations, inflammatory conditions, congenital or perinatal brain damages, migraine. Additional disturbances of visual space recognition (hemineglect), of colour vision and of reading ability (alexia). In connection with the above mentioned theme appreciation of the scientific work of Prof. E. Aulhorn (Tübingen) regarding the perimeter apparatus, the perimetric examination technique and the interpretation of the perimetric results.
