Risk factor for myopia, and new directions in myopic prevention and control
Presented by Ian Morgan
Recent work on risk factors for myopia has established that there are two major environmental exposures driving the current epidemic of myopia. Exposure to the educational pressures inherent in the life of a school child is a causal risk factor, whereas increased time spent outdoors acts to prevent the development of myopia. Many other factors have been proposed, but none are well-established, and it needs to be established if they act independently of these two major factors. How strong these exposures are depend on social/political as well as individual/family decisions. There are promising reports of effective use of increased time outdoors to decrease the prevalence of myopia. Recent changes to the education system in mainland China, with decreased study pressures in the preschool and early primary school years and the development of full-service schooling provide significant opportunities for increased time outdoors. This, combined with effective methods of slowing the progression of myopia, such as low dose atropine, and contact and spectacle lenses that impose myopic defocus, should enable the epidemic of myopia to be brought under control over the next few years.

IMI white paper on clinical management of myopia
Presented by Prof James Wolffsohn
With the growing prevalence of myopia, already at epidemic levels in some countries, there is an urgent need for new management approaches. However, with the increasing number of research publications on the topic of myopia control, there is also a clear necessity for agreement and guidance on key issues, including on how myopia should be defined and how interventions, validated by well conducted clinical trials, should be appropriately and ethically applied. The International Myopia Institute’s (IMI) mission is to advance research, education, and management of myopia to reduce future vision impairment and blindness associated with increasing myopia. Its approach is to bring together scientists, clinicians, policy makers, government members and educators into the field of myopia to stimulate collaboration and sharing of knowledge. The IMI white papers published in 2019 provided critical review and synthesis of the research evidence to-date, from animal models, genetics, clinical studies and randomized controlled trials, by over 85 multidisciplinary experts in the field. The seven generated reports summarized: Defining and Classifying Myopia; Experimental Models of Emmetropization and Myopia; Myopia Genetics; Interventions for Myopia Onset and Progression; Clinical Myopia Control Trials and Instrumentation; Industry Guidelines and Ethical Considerations for Myopia Control; Clinical Myopia Management Guidelines. The latest 2021 white paper are on pathologic myopia, the impact of myopia, risk factors for myopia, accommodation and binocular vision in myopia development and progression, and prevention of myopia and its progression. Together with the digest updating the 2019 IMI white papers using the research published in the last 18 months, these evidence-based consensus white papers help to clarify the imperative for myopia control and the role of environmental modification initiatives, informing an evidence-based clinical approach. This includes who to treat and when to start or stop treatment, and the advantages and limitations of different management approaches.

Treatment options for myopia control
Presented by Dr Tzu-Hsun Tsai and Prof Pauline Cho

Aired on 14 August 2022

While there is no known direct link between the mechanisms behind myopia development and dry eye, they can be linked in a number of ways. Increased near work and time outdoors are lifestyle environments associated with myopia development and progression and both are risk factors for dry eye disease, in particular due to the impact of digital display use on blinking. Contact lenses are one of the key treatments that have emerged to reduce myopic progression, while contact lens use can impact both aqueous deficient and evaporative dry eye disease. Research suggests the meibomian glands can be damaged through contact lenses wear, impairing the quality and stability of the tear film. Pharmaceutical approached for myopia control may contain preservatives or stabilising agents that can disrupt the tear film and ocular surface. Therefore while myopia is primarily related to the posterior eye, monitoring of the anterior eye is also critical in this population.

In managing myopia, refractive error assessment are commonly used to diagnose and monitor myopia. Recent optical biometers utilizing partial coherence interferometry and swept source techniques allow for rapid and non-invasive measurements of axial length.  Although a refractive error value is still needed to diagnose an eye as being myopic, measurements of axial length allow for more accurate monitoring of myopia progression. This talk will discuss the value of using axial length and axial length/corneal curvature measurements in screening and managing myopia.  Use of axial length and axial length/corneal curvature percentile charts provide a visual method to rapidly determine probability of myopia and monitor those at risk of myopia in specific populations. The talk will also discuss percentile charts and their value in monitoring progression of myopia.

This presentation discusses how Artificial Intelligence (AI) can be leveraged as a critical tool to go deeper into data for uncovering novel findings.  A deep learning approach for Meibomian gland features is applied for gland phenotyping and classification.  Results from the recent studies conducted at the UC Berkeley Clinical Research Center are presented to shed lights about what clinical signs and symptoms can be predicted by machine learning-driven Meibomian gland features and how AI approach predicts demographic characteristics from Meibomian gland images.  Knowledge gained from these studies may be relevant to the pediatric group for providing guidance to healthy ocular surface necessary for longevity of successful contact lens wear. Finally, a potential of meibography as biometric identifier and the capabilities of AI to disclose subject characteristics from de-identified medical imaging are also discussed.

Visit My Clinic
Presented by Pei-Chang Wu
Myopia control is important for preventing children myopia onset and progression. Because high myopia -5 diopter would induce complications associated blindness. Once children have myopia, it will progress -1 D per year and often become high myopia 5 year later. If a child come to our clinic in Kaohsiung Chang Gang Medical Hospital Myopia Center, he will receive cycloplegic refraction and correction examination to eliminate the pseudomyopia condition. We will have the baseline refraction status of the children and to classify his refraction as hyperopia, premyopia and myopia. For myopia control, we have pharmacologic and optic intervention including atropine, orthokeratology, bifocal soft contact lens and defocus incorporated multiple segments spectacles. For premyopia, increased time outdoors should be encourage and low concentration of atropine would be considered. Near work breaks, cram school and smartphone time control also should be noticed. Periodic monitoring the refraction change and medical compliance should be follow-up up to 18 years old.
