Blur adaptation in children wearing orthokeratology

After 1 month of wearing orthokeratology lenses, children were shown to have reduced accommodative lag and increased blur sensitivity, leading to the suggestion that blur adaptation is conducive in achieving good visual acuities and visual function in ortho-k wear.

Dual focus contact lenses and near viewing

This study examines the effect that dual focus contact lenses have on accommodation and defocus during near viewing, and the results provide clues towards understanding the myopia control mechanism of these contact lenses.

What is the effect of low-dose atropine on binocular vision?

Low-dose atropine (0.05% or less) has a maximum effect on pupil size for both bright and dim light conditions within an hour of instillation, but has little to no effect on binocular vision in myopic children when used for myopia management.

IMI Report on Accommodation and Binocular Vision in Myopia Development and Progression

This paper has found there are numerous correlations but only weak evidence to demonstrate a causal link between accommodation and myopia development. Assessment of the young myope’s accommodation and binocular vision function is still important. More understanding of the underlying mechanisms for myopia is needed in order to develop evidence-based interventions.

How do myopia control contact lenses impact binocular vision?

This study showed that aspheric multifocal soft contact lenses (Biofinity +2.50D and NaturalVue) reduce accommodative response and increase exophoria, while MiSight concentric dual-focus minimally impacts binocular vision function compared to single vision contact lenses. All myopia control contact lenses increased divergence range slightly but did not impact convergence.

What happens to binocular vision during cycloplegia?

Do you check your patient’s binocular vision function after cycloplegic refraction? Is this useful? An unexpected finding in this case leads to discussion of binocular vision changes in cycloplegic conditions, ideal management for exophores, and even the impact of low-dose atropine.

Four reasons why binocular vision matters in myopia management

Binocular vision is a much neglected (and even maligned?) domain of eye care where I’ve had numerous colleagues say their professional excitement and learning opportunities have been reinvigorated through seeing the clinical imperative and application in practice. Not only does binocular vision assessment add so much more to your clinical picture, and make optometric life more interesting, it could be the secret sauce that helps us bridge the gap towards 100% efficacy.

Is it really fast progressing myopia, or something else?

In this case, a 14-year-old was found to be far less myopic than their refraction and terrifyingly fast progression suggested, thanks to careful diagnosis. Learn what didn’t add up and how utilizing technology o measure the ocular components helped to solve the puzzling clinical case.
