April 7, 2018 :: http://www.optometry.org.au/qld/professional-development-events/australian-vision-convention.aspx :: Mark presented the latest research on Myopia Control for kids with progressive myopia and the use of orthoK for this. The incidence of myopia slide highlighted: 1 in 6 of the world’s population is myopic (2018) :: 1/3 of these reside in SE Asia :: Taiwan close to 90% of young adolescents are myopic - The highest rates of myopia are seen in Asians and Latin Americans (BHVI) :: USA myopia has doubled in the last 20 years :: By 2020 we expect to have 2.5 Billion (32%) people on the planet with myopia :: The prevalence among Australian 12-year-olds doubled between 2005 and 2011 :: Age of onset seems to be lowering :: From this Mark went on to highlight: Myopia has been described as a classic industrial disease and a adaption of modernity and as such by definition is not easy to prevent and treat. It is interesting that the rates are now increasing with reading materials now emitting light and are not simply written sheet. Research is targeted at 5 causative factors: Genetics (predisposition not a destiny) - Environmental influences (light, near work, exercise, diet, retinal defocus) - Behavioral influences - Time spent outdoors and - Hours of near work + Binocular Vision Status :: It really is the length of the eye that matters in Myopia as: The chance of vision impairment by age 75: An axial length of 30mm or more means a 90% risk - Axial lengths between 26 and 30mm are associated with a 25% - Onset likely to be earlier in the 28-30mm group :: So what have we done at Mark Hinds Optometrists? We have invested heavily in diagnostic equipment such as a Zeiss IOL Master and OCT technology the measures the length (biometry) of the eye so we can measure change and adjust treatment accordingly. We are dedicated to myopia control as: :: The prevalence among Australian 12-year-olds doubled between 2005 and 2011!!!!!!!
