Adverse event rates in paediatric soft contact lens wear

By Clare Maher | November 16, 2020 | 0 Comments

This retrospective cohort study established the prevalence of adverse events in children wearing soft contact lenses, and found them comparable to established rates among adults wearing soft CLs.

Retinal pathology is common in younger people with high myopia

By Ailsa Lane | November 28, 2022 | 0 Comments

This hospital-based study of high myopes aged 12 to 47 years found that myopia-related retinal pathologies were common, especially with more than 8D of myopia, greater than 26.5mm axial length and longer durations of myopia. Age and family history were not associated with retinal pathology – highlighting the need for close retinal health monitoring in high myopes of all ages.

Is peripheral vision and reading speed affected by aspherical lenslet spectacle lenses?

By Ailsa Lane | November 14, 2022 | 0 Comments

Peripheral vision function and reading speed were unaffected by highly aspherical (HAL) and slightly aspherical lenslet (SAL) spectacle lens designs compared to single vision lenses. Low contrast acuity was slightly reduced through the lenslet zone.

How could man-made environments influence childhood development of myopia?

By Ailsa Lane | November 1, 2022 | 0 Comments

This study demonstrated that man-made indoor environments may provide a myopigenic effect from reduced illumination and spatial frequencies. More research is needed to confirm if the mechanism for form deprivation from reduced spatial frequencies in humans is similar to that found for animals, and what improvements can be made to indoor environments to offset the risk for myopia.

Frequency and prediction of myopic macular degeneration in adults

By Ailsa Lane | November 1, 2022 | 0 Comments

This Singapore study found that 10-12% of ALL adult myopes aged 40-80 years – not just high myopes – suffered either onset or progression of MMD over 12 years. Risk factors included each additional year of age and 1mm of axial length. The most significant predictive sign was tesselated fundus.

How does the myopic peripheral retina respond to multifocal contact lens wear?

By Ailsa Lane | November 1, 2022 | 0 Comments

Analysis of the BLINK study results showed a global more than localized impact on slowing eye growth in +2.50 CD multifocal contact lens wear. The slowed growth effects were greater centrally than peripherally. This suggests local defocus responses may not provide the full story behind myopia control mechanisms.

The effect of online learning on myopia progression

By Ailsa Lane | October 17, 2022 | 0 Comments

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.

A study of myopia progression in France

By Ailsa Lane | October 17, 2022 | 0 Comments

This large cohort study analysed myopic prescriptions from 136,333 French children and teens. Factors influencing myopia progression were found to include a child’s age, gender and refraction of their first optical correction. Children aged 7-10yrs showed the fastest progression.

The difficulty in identifying fast-progressing myopes based on prior progression

By Ailsa Lane | October 3, 2022 | 0 Comments

Prediction modelling for future myopic progression was found to be more accurate when factors such as age, sex and ethnicity were considered, rather than prior progression. Myopia management should be initiated when myopia is apparent regardless of prior progression, rather than waiting to assess the progression rate.

Can previous progression predict future myopia?

By Ailsa Lane | October 3, 2022 | 0 Comments

The SCORM study analyzed the relationship between myopia progression a year after baseline and subsequent 2-year progression for myopic Singaporean children. Progression and age at baseline were found to be strongly associated with subsequent progression. However, they were shown to have limited predictive values and other factors are likely to determine future progression.
