[Ocular vasospasm. 1: Functional circulatory disorders in the visual system, a working hypothesis]

Abstract

Patients with normal-tension-glaucoma and with visual field defects of non-known origin, often suffer from mild vasospasm in the fingers. The observation often be provocated by coldness or emotional stress and that these defects can very often be reduced by a treatment of the vasospasm led to the hypothesis that a functional dysregulation of the circulation in the visual system might occur.
