Monocular Visual Field Defect on Humphrey 24-2 SITA-Fast Testing Later Identified as a Highly Incongruous Homonymous Defect on Humphrey 30-2 SITA-Fast Testing

Case Reports in Ophthalmology, 2021
Monocular visual field defects generally localize at or anterior to the optic chiasm, while homonymous hemianopias localize to the retrochiasmal visual pathway.

Estimating the Lead Time Gained by Optical Coherence Tomography in Detecting Glaucoma Before Development of Visual Field Defects

Ophthalmology (Rochester, Minn.), 2015
Purpose To estimate the diagnostic accuracy and lead time gained by retinal nerve fiber layer (RNFL) thickness measurements from optical coherence tomography (OCT) for detecting glaucoma before the development of visual field defects.

Automated Static Perimetry for diagnostics of visual field defects in glaucoma

Journal of Ophthalmology, 2019
Progression of glaucomatous optic neuropathy results in the development of specific visual field defects, which dictates the need for careful visual field testing in glaucoma patients in addition to monitoring intraocular pressure and the optic disc ...

Visual field defects in obstructive hydrocephalus [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 1982
Four cases are described in which visual field defects followed enlargement of the third ventricle. Three were due to aqueduct stenosis while in one case a left cerebellar hemisphere tumour was discovered. The visual field defects comprised a unilateral scotoma, bilateral scotomata and, in two patients, incongruous bitemporal hemianopia.

Hemisphere opposite to vascular trunk deviation is earlier affected by glaucomatous damage in myopic high-tension glaucoma.

PLoS ONE, 2020
PURPOSE:To investigate whether the position of the central vascular trunk, as a surrogate of lamina cribrosa (LC) shift, is associated with the initial hemisphere of visual field defect in myopic high-tension glaucoma (HTG) eyes. METHODS:The deviation of

The Effects of Compensatory Scanning Training on Mobility in Patients with Homonymous Visual Field Defects: A Randomized Controlled Trial

PLoS ONE, 2015
Introduction Homonymous visual field defects (HVFD) are a common consequence of postchiasmatic acquired brain injury and often lead to mobility-related difficulties.

Transient but Significant Visual Field Defects after Robot-Assisted Laparoscopic Radical Prostatectomy in Deep Trendelenburg Position

PLoS ONE, 2015
Background Robot-assisted laparoscopic radical prostatectomy (RALP) is a minimally invasive surgical procedure for prostate cancer. During RALP, the patient must be in a steep Trendelenburg (head-down) position, which leads to a significant increase in ...
