[Current significance of keratopathia neuroparalytica].

Among the complications after surgical interventions carried out on the Ganglion semilunare because of a trigeminal neuralgia the reason why Keratopathia neuroparalytica plays a role is the fact that it very frequently leads to partial or total blindness of the affected eye. The pathogenesis of the keratopathy is still being disputed. The appraisal of the various surgical methods in trigeminal neuralgia always includes the frequent occurrence of a keratopathy. Among the 171 patients who were operated on in Halle because of trigeminal neuralgia in the last ten years no keratopathy was observed. In 12 cases a reduction or removal of the corneal reflex was brought about. On 8 patients a postganglionic intradural operation was carried out, all others received an electro-coagulation. The co-operation with the ophthalmologist is indispensable both prophylactically and therapeutically.
