Measuring near lag of accommodation

Assessing accommodative function, such as measuring near lag of accommodation, is a vital component of understanding the myopia profile of your patient. In this post Dr Kate Gifford describes how to measure accommodation lag in practice.

A myope or not? Pseudomyopia, antimetropia and more

Refraction can be challenging in children, and even more so in a complex presentation as for this case. Is this patient a myope or not? When dealing with a complex case of pseudomyopia, antimetropia and latent hyperopia, all in one patient – how should we manage the patient? The answer involves balancing goals to manage ametropia correction, binocular vision function and myopia control. 

Managing a 5-year-old pre-myope

Pre-myopes can be readily identified, and best practice dictates that we should offer some form of intervention to help delay the onset of myopia. In this case we discuss the features of a pre-myope and an example in a 5 year old patient who satisfies the refractive criteria for pre-myopia, and has a strong family history of myopia.

Do you need to treat esophoria in an emmetropic patient?

Esophoria at near is a risk factor for myopia development and progression. Does it need to be managed in an emmetropic patient without symptoms? Is this patient a pre-myope, and how should this factor into management? Read this interesting clinical case, where colleagues discuss whether to intervene or not, and how to potentially manage both myopia risk and binocular vision.

Accommodation training in multifocal contact lens wear

This study showed that multifocal contact lens wear in young adult myopes increases accomodative lag, and utilized auditory biofeedback training to improve it. The results and implications are discussed here.

When to prescribe spectacles for myopia control

Here we explore an overview of spectacle prescribing for myopia management – from when to use single vision, to progressive and bifocal designs, new myopia control specific designs, and whether to fully or under-correct.

Managing a myopic anisometropic amblyopic child

This case is not your typical astigmatic myope. There are several features to this patient that require careful consideration, including high myopia, amblyopia, myopia correction and control, and eye health management.
