Assessment of Stereoacuity in Patients with Strabismus
PURPOSE: To analyze the stereoacuity in patients with strabismus using various stereotests. METHODS: Stereoacuity was assessed in children diagnosed as intermittent exotropia or refractive accommodative esotropia using Titmus stereotest, TNO stereotest, and Lang stereotest. Patients with amblyopia …

The Effect of interocular Difference of Retinal Illuminance on Streopsis
… distanceand nearbestcorrected visualacuity and stereoacuity with Titmus, TNO and Lang stereotest.We used neutraldensity filterfrom 0.2 neutral density(ND)to3.0ND withintervalsof0.2ND. RESULTS: The distance and near best corrected visualacuity began to decreasesignificantly when …

The Effects of Binocular Vision Impairment on Adaptive Gait. The effects of binocular vision impairment due to monocular refractive blur on adaptive gait involving negotiation of a raised surface.
Impairment of stereoacuity is common in the elderly population and is found to be a risk factor for falls. The purpose of these experiments was to extend knowledge regarding impairment of binocular vision and adaptive gait. Firstly using a 3D motion analysis system to measure how impairment of …

An investigation of stereopsis with AN/AVS-6 night vision goggles at varying levels of illuminance and contrast
… and without AN/AVS-6 goggles were investigated. Stereoacuity was measured using a modified Howard-Dolman apparatus with four levels of illumination and three levels of contrast. Testing was performed with NVGs for nighttime illuminations and unaided for daytime levels of illumination. Image …

CLINICAL USEFULNESS OF OCULAR TESTS FOR DIAGNOSING CONCUSSIONS
… (NPC), the King-Devick Test (KDT), and stereoacuity can be performed to identify and assess these deficits, but their diagnostic accuracy has yet to be thoroughly investigated. The purpose of this study was to determine if differences exist in NPC, KDT, and stereoacuity test scores …

Validity and usability of a virtual reality intraocular surgical simulator
… we set out to investigate whether factors like stereoacuity and sex would be important for performance in the simulator. Evidence for construct validity was found for cataract specific modules capsulorhexis, hydromaneuvers and phaco divide and conquer and for manipulating modules cataract …

User-centered Virtual Environment Assessment And Design For Cognitive Rehabilitation Applications
… specifically resolution visual acuity and stereoacuity. Resolution visual acuity and stereoacuity assessments provide information about the image quality achieved by an HMD based upon its unique system parameters. When applying a user-centered approach, we were able to quantify limitations …

Low- and high-level motion deficits in amblyopia: studies of maximum motion displacement
… a robust correlation between depth perception (stereoacuity) and Dmax thresholds. Specifically, direction discrimination was better when stereoacuity was worse. Abnormal binocular integration may have a significant role in predicting motion deficits in both anisometropic and strabismic amblyopia.

Visual Function in New Zealand Children: from Preschool to Primary School
… vision screening (P = 0.01). Poorer near VA and stereoacuity were associated with reduced reading scores and eye movement patterns that were similar to those seen in younger and less proficient readers. Equity-based improvements are required to ensure detection and treatment of vision conditions …

Aniseikonia: A Potential Barrier To Neural Plasticity
… of all amblyopic eyes improved by 4 lines and stereoacuity improved by 2 octaves after 15 weeks of spectacle wear. Optical treatment was well tolerated, and adherence was high. However, broken or damaged spectacles can disrupt treatment and be a burden for families. The SpecsOn monitor was …

Aging and Stereoscopic Shape Perception
… has largely been limited to investigations of stereoacuity. The purpose of Experiment 1 was to extend this earlier research to compare how older and younger observers perceive the magnitude of stereoscopically defined depth intervals. Random-dot stereograms depicting sinusoidal surfaces were …
