Diagnosis and treatment of occipital brain lesions in children

Developmental Medicine &Child Neurology, Volume 67, Issue 11, Page 1409-1420, November 2025.
Occipital brain lesions in children represent a diagnostic challenge due to the large spectrum of etiologies and overlapping clinical features. This review analyses common and less common causes of occipital brain lesions in children, including malformative, vascular, genetic/metabolic, infectious, inflammatory, and neoplastic conditions.

The effects of absence of stereopsis on performance of a simulated surgical task in two-dimensional and three-dimensional viewing conditions. [PDF]

, 2014
Stereopsis is believed to be advantageous for surgical tasks that require precise hand-eye coordination. We investigated the effects of short-term and long-term absence of stereopsis on motor task performance in three-dimensional (3D) and two-dimensional

The QuickSee autorefractor reliably measures the accommodative response in children compared with the Shin‐Nippon autorefractor

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1581-1590, November 2025.
Abstract Introduction This study evaluated the QuickSee autorefractor for measurement of the accommodative response in a cohort of children without significant ametropia, and compared the findings to those determined using the gold‐standard Shin‐Nippon device. Methods Children aged 5–7 years were recruited.

From Stereogram to Surface: How the Brain Sees the World in Depth [PDF]

, 2006
When we look at a scene, how do we consciously see surfaces infused with lightness and color at the correct depths? Random Dot Stereograms (RDS) probe how binocular disparity between the two eyes can generate such conscious surface percepts. Dense RDS do

Post‐concussion clinical findings of oculomotor function in paediatric patients with persisting symptoms compared to healthy controls

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1597-1607, November 2025.
Abstract Objective Oculomotor deficits in vergence and accommodation can arise in paediatric patients with persistent concussion symptoms, although the profile is not well established. This study aimed to describe the frequency of these deficits in persistently symptomatic concussed paediatric patients and identify effective screening tools.

Long‐term test and retest reliability of clinical vergence testing

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1630-1641, November 2025.
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∆

Linking Visual Cortex to Visual Perception: An Alternative to the Gestalt Bubble [PDF]

, 2003
Lehar's lively discussion builds on a critique of neural models of vision that is incorrect in its general and specific claims. He espouses a Gestalt perceptual approach, rather than one consistent with the "objective neurophysiological state of the ...

Parkinson's disease and reading performance

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1653-1661, November 2025.
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
