Abstract
An otherwise healthy 63-year-old woman was given a diagnosis of normal tension glaucoma (NTG) in the right eye (OD) 2 months before presentation. Standard computerized perimetry showed a unilateral right hemianoptic temporal field defect. On examination visual acuity was preserved, intraocular pressure was normal, there was a right relative afferent pupillary defect (RAPD) with an asymmetric cupping of the disc, but no pallor. Brain magnetic resonance imaging (MRI) showed a meningioma compressing the right optic nerve at its junction with the chiasm. Compressive disorders on the anterior chiasm, albeit rarely, may cause cupping of the disc and unilateral temporal visual field defect (junctional scotoma of Traquair) with normal visual acuity that should be considered in the differential diagnosis of NTG.
期刊介绍：
This new peer-reviewed online-only journal publishes original case reports covering the entire spectrum of neurology. Clinicians and researchers are given a tool to disseminate their personal experience to a wider public as well as to review interesting cases encountered by colleagues all over the world. To complement the contributions supplementary material is welcomed. The reports are searchable according to the key words supplied by the authors; it will thus be possible to search across the entire growing collection of case reports with universally used terms, further facilitating the retrieval of specific information. Following the open access principle, the entire contents can be retrieved at no charge, guaranteeing easy access to this valuable source of anecdotal information at all times.
