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 …

Binocular Vision – Easier Than You Think (Lecture)

This one hour lecture, delivered to final year QUT optometry students, describes a simplified two-system approach to BV diagnosis and management, with cases, then details easy use of prism correction for vergence disorders; changes to BV in contact lens wear; and why BV matters – for reading and learning in kids, clinical problem solving, and myopia management. By far the …

Prescribing adds for near esophoria

From a myopia control point of view, esophoria and accommodative lag are the key clinical red flags in assessing your patient’s visual efficiency, and thankfully both will usually respond positively to a near addition. Studies of progressive spectacle lens prescription for myopia control show a link between faster progression and hence better treatment results in children with esophoria and accommodative …

Assessing near phoria

I describe near heterophoria to my patients as where their eyes aim in space – the posture of their vergence system – and esophoria is our key enemy in the myopia control battle. There is a reported association between higher levels of esophoria and accommodative lag at near in myopic children and young adults as compared to emmetropes.1-5 Studies of progressive …

Prescribing adds for accommodation lag

Essential reading to preface the below are my notes on how to measure near lag of accommodation and how to measure accommodative facility. You can also watch how to measure accommodative lag on our Youtube channel. You’ll have already read how assessing accommodative function at near is a vital component of understanding the myopia profile of your patient. Myopic progression in …

Measuring accommodative facility

Assessing accommodative function at near is a vital component of understanding the myopia profile of your patient. Myopic progression in children and adults can be influenced by binocular vision function. There is a reported association between higher levels of esophoria and accommodative lag at near in myopic children and young adults as compared to emmetropes.1-5 Myopic children and young adults …
