Purpose: To evaluate the validity of electrophysiological tests in the early diagnosis of a ganglion cells and/or optic nerve dysfunction in patients with pituitary microadenoma.
Methods: 66 eyes, from 33 patients with microadenoma with no evidence of the optic chiasm compression in magnetic resonance imaging (MRI) and the visual impairment in the routine ophthalmological examination, standard static perimetry (24-2 white on white) and optical coherence tomography (HD-OCT), were analysed. The pattern electroretinogram (PERG), standard pattern visual evoked potentials (PVEPs) and multichannel visual evoked potentials (mVEPs) (ISCEV standards) were performed.
Background And Methods: Based on the available literature, it is suggested, in the clinical evaluation of the chiasmal tumors, that the following electrophysiological tests: visual evoked potentials to pattern-reversal stimulation, multifocal visual evoked potentials (mfVEPs), and pattern electroretinogram (PERG) play an important role in the diagnosis of the optic nerve and retinal dysfunction in the course of pituitary tumors.
Results: Macroadenomas and also microadenomas may cause dysfunction of retinal ganglion cells (RGCs) and their axons, even in the absence of changes in the routine ophthalmological examination, retinal sensitivity in standard automated perimetry, and retinal nerve fiber layer thickness in optical coherent tomography. The most frequently observed changes in electrophysiological tests were as follows: in PVEPs-the crossed/uncrossed asymmetry distribution, altered waveform, increase in P100-wave peak time, and/or reduction in amplitude; in mfVEPs-the peak time prolongation and/or amplitude reduction in C1-wave; in PERG-the reduction in N95-wave amplitude and decreased N95:P50 amplitude ratio.
Purpose: To present a patient with a diagnosis of pituitary adenoma and progressive visual pathway dysfunction detected in the electrophysiological tests in one-year follow-up. Patient is a 59-year-old male with a non-secreting pituitary macroadenoma.
Methods: Routine ophthalmological evaluation, standard automatic perimetry (SAP), retinal nerve fibers layer and the ganglion cell complex thickness in optical coherent tomography (OCT), as well as electrophysiological examinations (pattern electroretinogram-PERG, multi-channel pattern visual evoked potentials-multi-channel PVEPs record according to ISCEV standards) were performed.

The aim of this article is to present a clinical picture of congenital optic nerve anomalies, which occur quite frequently in the general population, may cause low vision and visual field defects. These abnormalities can coexist with central nervous system defects or the other ocular abnormalities. Some of them may be misdiagnosed as papilloedema during the episode of intracranial fluid pressure elevation or glaucomatous neuropathy.
View Article and Find Full Text PDFTersone syndrome was first described in 1900 as haemorrhages in the eye that occur as a consequence of intracranial hemorrhage. The main cause of the syndrome in adults is a subarachnoid hemorrhage following the rupture of intracranial aneurysm. The pathogenesis has not been fully understood.
