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.

Ophthalmic and Physiological Optics, EarlyView.Abstract Purpose To assess second‐year myopia progression in children after a 1‐year randomised controlled trial of individualised ocular refraction customisation (IORC) spectacle lenses, customised to each eye's peripheral refraction. Methods A total of 161 children were randomised to wear IORC lenses with high (+4.50 D, IORC‐H), medium (+3.50 D, IORC‐

Ophthalmic and Physiological Optics, EarlyView.Abstract Purpose Angle lambda (λ) is defined as the angle between the line of sight and the pupillary axis at the entrance pupil. We previously developed a child‐friendly and portable method to measure this angle in daily practice. In a given population, angle λ fluctuates according to age or refractive error.

Measuring glucose content in the aqueous humor [PDF]
, 2004 Many diabetics must measure their blood glucose levels regularly to maintain good health. In principle, one way of measuring the glucose concentration in the human body would be by measuring optically the glucose content of the aqueous humor in the eye ...

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.

Radiometric and safety assessment of a ‘low‐level red‐light’ myopia control device
Ophthalmic and Physiological Optics, EarlyView.Abstract Purpose Recent literature has demonstrated that ‘low‐level red‐light therapy’ may be effective at slowing axial elongation in children, but reports have questioned the safety of some red‐light devices. The current work explored the beam characteristics and hazard potential for a myopia control red‐light device.
