Mero Eye Foundation is introducing a Myopia Symposium. The symposium is the premier meeting solely focused on myopia and its management involving clinicians, researchers and educators from Brien Holden Vision Institue (BHVI), Australia. The Myopia Symposium provides cutting edge, clinical information based on the most current research for you to implement in your practice.

Our Objectives

To provide current global updates of myopia and control strategies

Topic 1

Global Myopia Epidemiology, Impact & Burden

Speaker

Consultant, Brien Holden Vision Institute & Brien Holden Foundation, Melbourne, Australia

Myopia is a large and growing problem, with many complexities disguised as a “simple” refractive problem. It has complex aetiologies, leading to interesting clinical management opportunities. At the clinical and public health level, it causes vision impairment in two ways: when a person with myopia is unable to access an adequate vision correction, and via susceptibility to a range of retinal and optic nerve head complications. This presentation will explore the epidemiology, burden and impact of myopia, high myopia and associated complications to provide context for the rest of the session: why is myopia a growing problem, and what can we do about it?

Topic 2

South Asia Regional Myopia Figure Including Nepal

Refractive error is the most common cause of vision impairment in the region. Unfortunately, only few countries in the South Asia region have published studies. There is marked variation in myopia prevalence in children across the countries in the region. For example, in urban North India, myopia prevalence in children increased from 7.4% to 13.1% from 2001 to 2015 (Saxena R et al) and increased further to 21.1% in 2018 (Hashemi H et al.). Refractive error in school children (RESC) study conducted in Mechi Nepal in 1998 reported a low prevalence (2.9%) of refractive error (Pokharel GP et al.). Unfortunately, the rate has significantly increased in the past two decades. With the analysis of recent published studies conducted in schoolchildren, the prevalence rates were found varying (1.9 to 20.9%), which could be attributed to varying geographical location, urbanization, and ethnicity. The overall result of this literature review shows that an average rate of refractive error prevalence among school children in Nepal is 7.9%, of which myopia constitutes about 5.9%. Further a rapid assessment of avoidable blindness study conducted in last 2 years suggests that the prevalence of refractive error in population over 50 years was 15 to 25% across the 6 provinces. Few studies conducted at schools revealed poor compliance to spectacle wear among schoolchildren. All these results suggest that there is a dire need for routine vision screening and eye health education and promotion at schools.

Topic 3

Optical Strategies To Control Myopia

Whilst both genetic and environmental factors are at play in the development and progression of myopia, evidence from work conducted using animal models demonstrates that eye growth is regulated by visual feedback and experience. Encouragingly, translation of information from these experiments and other cross-sectional human studies show that it is feasible to slow the progress of myopia with optical strategies. With respect to optical strategies, spectacles, contact lenses and orthokeratology have been employed. This talk will focus on the various spectacle lens and contact lens strategies, the hypotheses underlying these strategies, efficacy of the various approaches and inform on their role with respect to other strategies.

Topic 4

Pharmaceutical Strategies To Control Myopia

Speaker

Myopia is a global public health issue associated with significant risk of visual impairment or blindness especially in cases of high myopes, therefore its’ progression needs to be controlled. Clinical data supports a greater efficacy in slowing myopia progression of the pharmaceutical strategies, especially atropine eye drops, than that observe with the optical methods. Multiple candidate compounds have been investigated as potential pharmaceutical strategies including intraocular pressure-lowering agents, cycloplegic agents such as tropicamide or cyclopentolate, non-selective or selective anti-muscarinic receptor agents as pirenzepine. However, due to inconsistent proven effect or unknown reasons, only atropine eye drops have been widely adopted in many parts of the world and it’s myopia control efficacy is consistently proven. Low-dose atropine has been widely applied with the aim of reducing the common side-effects. Nonetheless, the effect of low-dose atropine on axial elongation is still doubtful which generates the two main questions to be investigated further: 1) what is the optimal dose of atropine with tolerable side-effects? 2) is there other pharmaceutical candidate compound?

Topic 5

Environmental approaches & public health strategies for myopia control

Speaker

Dr Krupa Philip

Myopia is multifactorial in origin with both genetic and environmental risk factors at play. Evidence indicates a strong association between near work and myopia with an early start of education or exposure to near work at a younger age further increasing the risk of myopia. More importantly, children and young adults with environmental risk factors such as less time outdoors, less ambient light in classrooms, less exposure to sunlight and bright light are at higher risk of becoming myopic. Other factors such as urban environments, high population density, constricted living space and housing type (living in apartments) also increases the likelihood of developing myopia. This talk is aimed to provide a detailed summary of various environmental factors that lead to myopia and the public health strategies that should be in place to prevent or control the myopia epidemic.
