Axial length (AXL) has been well established as the critical measurement in myopia control research. The measurement accuracy and link to disease risk make AXL increasingly important in a clinical setting. But what else should we measure in the myopic eye? Does the cornea change as well? Will we end up doing away with refraction? Read more on measuring the whole eye in myopia.
We all know that high myopia is associated with higher incidences of retinal detachment, glaucoma and myopic maculopathy1. Instigating early, evidence based myopia control in rapidly progressing myopes gives the best outcomes both pathophysiologically and refractively. However when faced with a low, slower progressing myope, or a patient whom has already progressed is there any point in persisting with myopia control?
Only a minimal percentage of children are likely to suffer dry eye symptoms (4%) compared to 56% in adult contact lens wearers.(1) Teens may be more likely to report contact lens related dry eye than younger children,(2) and consideration should be given to any systemic medications which could exacerbate dry eye symptoms, such as acne medications and those taken for anxiety and depression.
Most eye care practitioners don’t routinely measure axial length in clinical practice, mainly due to lack of access to the instrumentation and its expense. This is not the only reason, though, that axial length (AXL) measurement is a bit of a problematic measure for gauging myopia management success in a clinical setting.
It is commonly understood that myopia prevalence is growing globally. By 2050, it is predicted that half of the world’s population – five billion people – will be myopic, with nearly one billion at risk of myopia related ocular pathology. The late Brien Holden was a champion of ensuring myopia is placed on the world health agenda – high myopia is strongly linked to higher risk of cataract, retinal detachment and myopic maculopathy, and increasing rates of vision impairment and blindness due to the latter are already evident in Asian countries.
