Fluctuations in angle lambda with the pupil diameter and correlations with biometric values in a healthy population

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.

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

Vector analysis of corneal astigmatism in cataractous eyes based on IOLMaster 700 biometry.

PLoS ONE
PurposeThe purpose of this study was to investigate the effect of the corneal back surface by comparing the keratometric astigmatism (K, derived from the corneal front surface) of a modern optical biometer against astigmatism of Total Keratometry (TK ...

High myopia following unilateral cryocoagulation for threshold retinopathy of prematurity [PDF]

, 2016
Despite the proven benefit of cryotherapy in the management of threshold retinopathy of prematurity (ROP), it was shown leading to ocular adverse effects. A male infant was born at 28 week of gestation with a birth weight of 1200 g.

Targeted perimetry for mapping the shape of glaucomatous arcuate scotomata

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose Recent work has shown potential benefits for perimetry with dense spacing. To investigate the impact of normal inhomogeneity of perimetric sensitivity on perimetry with dense spacing, suprathreshold perimetry was used near the optic disc where shadows of blood vessels affect sensitivity in healthy eyes.

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.
