Point-wise variability of threshold sensitivity of 24-2 and 10-2 visual fields

Taiwan Journal of Ophthalmology, 2022
PURPOSE: To evaluate point-wise variability of threshold sensitivity at different test locations on 24-2 and 10-2 visual field (VF). MATERIALS AND METHODS: Electronic medical records of patients seen at a tertiary eye care center were screened to include

Opposite response of blood vessels in the retina to 6° head-down tilt and long-duration microgravity

npj Microgravity, 2021
The Spaceflight Associated Neuro-ocular Syndrome (SANS), associated with the headward fluid shifts incurred in microgravity during long-duration missions, remains a high-priority health and performance risk for human space exploration.

Reliability of Visual Field Index in Staging Glaucomatous Visual Field Damage [PDF]

Journal of Clinical and Diagnostic Research, 2018
Introduction: Standard automated perimetry is integral to the testing of visual function in glaucoma. Classification of glaucomatous visual field defects into different severity levels is important to guide effective management; but the available ...

Spectacles with highly aspherical lenslets for myopia control do not change visual sensitivity in automated static perimetry

Frontiers in Neuroscience, 2022
PurposeSpectacle lenses with arrays of lenslets have gained popularity in myopia control due to their high efficacy, low impact on visual performance, and non-invasiveness.

Slowed Saccadic Reaction Times in Seemingly Normal Parts of Glaucomatous Visual Fields

Frontiers in Medicine, 2021
Purpose: In eye movement perimetry, peripheral stimuli are confirmed by goal-directed eye movements toward the stimulus. The saccadic reaction time (SRT) is regarded as an index of visual field responsiveness, whereas in standard automated perimetry (SAP)

Vigabatrin-Associated Visual Field Defects

Pediatric Neurology Briefs, 2001
The prevalence, risk factors, and long-term outcome of vigabatrin-associated visual field defects were examined in 60 adult patients with partial epilepsy treated with vigabatrin for 7 months to 14 years at the University of Kuopio Hospital, Finland.

Vigabatrin-Induced Visual Field Defects

Pediatric Neurology Briefs, 1998
A drug surveillance database at Hoechst Marion Roussel, manufacturers of vigabatrin, identified 92 cases of symptomatic visual field defects associated with vigabatrin (usually as add-on therapy) between 1990 and 1997.
