Long‐term test and retest reliability of clinical vergence testing
Abstract Purpose To establish long‐term reliability measures for vergence testing in a control population of adolescents. Methods Healthy participants between 12 and 17.5 years with normal binocular vision were recruited from 10 clinical sites. Cover test, near point of convergence (NPC), positive and negative fusional vergences, vergence facility (12∆

: Stereopsis is the perception of depth based on retinal disparity. Global stereopsis depends on the process of random dot stimuli and local stereopsis depends on contour perception.

Stereopsis among Medical Students [PDF]
Background and purpose: Depth perception (stereopsis) is the ability to perceive depth in visual space through sensory integration of retinal images in both eyes and is achieved through binocular perception in specific visual pathways in the cerebral ...

Parkinson's disease and reading performance
Abstract Purpose Visual and reading difficulties affect 80% of individuals with Parkinson's disease (PD). Despite this, reading speed (RS) in PD has not been studied extensively. This investigation aimed to compare RS and reading acuity (RA) in participants with PD and in a control group (CG) using the Radner–Vissum reading charts. Methods CG inclusion

Impact of contact lens correction on wavefront aberrations and vision quality in keratoconus
Abstract Purpose To review the optical principles of contact lens correction in keratoconus, with a focus on residual ocular wavefront error and its impact on vision performance. Findings Corneal rigid gas permeable (RGP) contact lenses, commonly used in keratoconus management, often fail to improve vision quality to levels observed in non‐diseased ...

Overestimation of stereo thresholds by the TNO stereotest is not due to global stereopsis
It has been repeatedly shown that the TNO stereotest overestimates stereo threshold compared to other clinical stereotests. In the current study, we test whether this overestimation can be attributed to a distinction between ‘global’ (or ‘cyclopean’) and

Stereopsis, Visuospatial Ability, and Virtual Reality in Anatomy Learning
A new wave of virtual reality headsets has become available. A potential benefit for the study of human anatomy is the reintroduction of stereopsis and absolute size.
