By using a wearable device to objectively monitor visual behaviour, this study found progression in young myopic children was correlated with less time outdoors, more time working at near for online learning and less time spent wearing their glasses.
Orthokeratology is effective for myopia control but is it suitable for a child with trichiasis and corneal staining? This case compiles the treatment suggestions for managing a young myopic patient with trichiasis from the Facebook community, with a focus on safety.
This study showed that multi-zone spectacle and contact lenses used for myopia control provide myopic defocus at far distances. At near, changes in accommodative lag, pupil miosis and spherical aberration in individuals may mean there are lesser amounts of myopic defocus and reduced image quality. However, all the lenses were still able to provide sufficient image clarity at near for typical size print.
This cross-over study investigated children wearing highly aspherical lenslet (HAL) spectacle lenses versus single vision spectacles over three six-month periods. The HAL lenses showed consistent myopia control efficacy and no rebound effect when discontinued over one of the six-month periods.
In myopic children, interventions to slow progression are warranted to prevent the development of high myopia and subsequent pathology and also to reduce the economic burden caused by uncorrected and pathologic myopia. This IMI Report describes the latest advice on preventing the development and progression of myopia – read the summary here.
This case is highlights that myopia management decision making includes much more than a child’s refraction. Learn how Keyur Patel involved the parent in the conversation and decision making, to determine the starting myopia management option for now, as well as considering the future.
This study reports two year results from a randomized clinical trial examining myopia control spectacle lenses with highly aspherical lenslets (HAL) or slightly aspherical lenslets (SAL). The findings showed the HAL lens controlled refractive and axial progression by 50-55% and SAL by around 30% over two years. Read more about the outcomes and comparisons to other myopia control spectacles here.
This systematic review of 9 studies confirms that under-correction of myopia does not slow progression; rather, at least half of the studies have shown the myopia progression is accelerated. There was no benefit found in overcorrection, and the evidence for un-correction was equivocal. Clinically, this advocates for the full correction of myopia.
The myopia history in childhood can influence how an adult myope copes with their correction and even how their vision changes over time. Read more about this case of a 50-year-old progressing myope.
This study reported that children wearing DIMS spectacle lenses showed increased sub-foveal choroidal thickness than controls at 1 week which increased in the first 6 months and was maintained at 2 years. There was a correlation between more choroidal thickening and less axial elongation, but choroidal thickening only explained around 8% of the variation in axial length.
