19th Hong Kong International Optometric Symposium

Presentation Topic  - Myopia Management – Non-pharmacological Options This course presents evidence-based information on the non-pharmacological options available for myopia management. The course will cover the types of spectacle options that have been proven to be effective for myopia management as well as the contact lens options that are available. Efficacy of the various options will be discussed as well as information on how to interpret the scientific literature. By the end of the course the learner will: 1. Have knowledge of the prevalence of myopia 2. Be aware of the risks associated with progressive myopia 3. Have knowledge of the types of spectacle lenses that have been suggested for myopia management that have not demonstrated good efficacy 4. Have knowledge of the types of spectacle lenses that have been created specifically for myopia management 5. Have knowledge of the types of contact lenses that can be used for myopia management 6. Be aware of the mechanisms of actions of the various contact lens options available

Presentation Topic  - Refractive Error Changes in Hong Kong Children during COVID-19 Pandemic and Combination Therapy for Myopia Control

Presentation Topic  - Refractive Error Changes in Hong Kong Children during COVID-19 Pandemic and Combination Therapy for Myopia Control The first part of this course will review the risk factors for astigmatism and myopia development, followed by presenting recent research on the change of refractive errors in the Hong Kong schoolchildren population. The second part will review stand-alone orthokeratology (ortho-k) and 0.01% atropine treatments, including effectiveness, adverse events, limitations, and mechanisms. This will be followed by a presentation of a recent study using combination of the two treatments for myopia control. The efficiency of the combined treatment will be discussed.

Presentation Topic - Strategies and Public Health Policies on Myopia Myopia is fast becoming a global public health burden with its increasing prevalence, particularly in developed countries. Globally, the prevalence of myopia and high myopia (HM) is 28.3% and 4.0%, respectively, and these numbers are estimated to increase to 49.8% for myopia and 9.8% for HM by 2050. The burden of myopia is tremendous as adults with HM are more likely to develop pathologic myopia (PM) changes that can lead to blindness. Accordingly, preventive measures are necessary for each step of myopia progression toward vision loss. Approaches to prevent myopia-related blindness should therefore attempt to 1. prevent or delay the onset of myopia among children - by increased outdoor time 2. stunt progression from low/mild myopia to HM – through optical (e.g. defocus incorporated soft contact, orthokeratology, and progressive-additional lenses) and pharmacological (e.g. low dose of atropine) interventions 3. stunt progression from HM to PM – through medical/surgical treatments (e.g. anti-vascular endothelial growth actor therapies, macula buckling and scleral crosslinking). Recent clinical trials aiming for retarding myopia progression have shown encouraging results.

Presentation Topic - Public Health Policies and Strategies on Myopia in Mainland China The prevalence has been ascending in the past 20 years and reached to over 50% in school students in the Mainland China. The situation has resulted in severe impact in not only the patients themselves, but also the family as well as the society. Under this circumstance, Chinese central government is taking national action to tackle this problem. This course will introduce relevant public health policies and strategies, as well as recent achievements reported by representative regions. presents recent policies and strategies on myopia implemented by Chinese Central Government.

Presentation Topic - Surgical Management of Myopic Complication: Macular Hole Associated Retinal Detachment This course will cover the current management approach of the sight threatening complications associated with myopia. Course Learning Objectives: • To enable the recognition and the current management of the different sight threatening complications associated with myopia. • To review the different pathological features of myopic degeneration and its effects to the vision and prognosis. • To understand the pathophysiology and the current management approach of myopic foveoschisis, retinal detachment and myopic macula hole. • To review the pathophysiology and the current management of myopic choroidal neovascular membrane

Presentation Topic - Infection Control in Optometric Practices This course presents the principles of infection control and how that relates to optometry practice. It will look at transmission of infection and principles of cleaning, sterilisation, disinfection. It will cover methods to prevent the transmission of infection including personal protection and cleaning and decontaminating the equipment in a consulting room. The COVID-19 pandemic will be considered and the changes that are required to enhance infection control and manage patients safely.
