The Waterloo Differential Acuity Test (WatDAT)—Testability and normative data

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose To investigate the testability of the WatDAT for measuring recognition visual acuity (VA) in children aged between 18 to 48 months, report preliminary age‐related data and compare with two commercially available matching tests. Methods A total of 57 children (18.5–45.8 months) attended for two sessions.

Compensatory Interactions between Corneal and Internal Astigmatism despite Lifestyle Changes

Children
This study explores whether children’s refractive errors and visual behaviors reverted to pre-COVID-19 levels a year after normal schooling resumed in Hong Kong as well as the impact of corneal and internal astigmatism on refractive astigmatism ...

The prevalence and costs of optical correction for childhood myopia in Scotland

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose General Ophthalmic Services in Scotland (GOS(S)3) vouchers provide children with National Health Service (NHS)‐funded optical correction. This study investigated the financial impact of myopia by reporting current spending on GOS(S)3 vouchers and indicative prevalence of childhood myopia in Scotland.

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.

Response of accommodation and vergence systems to low dose atropine

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose Few studies have comprehensively investigated the effect of low dose atropine on the binocular vision system beyond accommodative amplitude. This study examined the effect of 0.05% atropine eye drops on a range of accommodation and vergence parameters across a 10‐day period. Methods Twenty myopic, adult participants (mean age [SD] 22.3

Myopia control and modulation transfer functions for multisegment spectacle lenses

Ophthalmic and Physiological Optics, EarlyView.
Abstract Introduction Multisegment (MS) spectacle lenses, providing a distance correction with a clear central area and by having an array of small, positively powered lenslets in the periphery of the front surface, have proved effective in slowing childhood myopia progression.
