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

Ophthalmic and Physiological Optics, EarlyView.
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.

Influence of time‐of‐day and light wavelengths on ocular responses to defocus

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose This study explored potential effects of time of day and light filters on the ocular response to 1‐h myopic defocus and associated changes in melatonin. Methods Twenty healthy myopic adults (mean age ± SD: 25.9 ± 3.9 years; spherical equivalent: −4.12 ± 1.00 D) participated in this study.

Long‐term test and retest reliability of clinical vergence testing

Ophthalmic and Physiological Optics, EarlyView.
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∆

The role of astigmatism in myopia development, myopia progression and myopia control

Ophthalmic and Physiological Optics, EarlyView.
Abstract Aims/Purpose Myopia arises primarily due to excessive axial elongation and is associated with an increased risk of ocular complications and visual impairment, particularly in high myopia. Although astigmatism may have implications on refractive development, the role of astigmatism in myopic eye growth and the effectiveness of myopia control ...
