Larissa’s Insights from the 19th International Myopia Conference in Sanya, China
I had the opportunity to attend the 19th International Myopia Conference (IMC) in Sanya, China, where I presented my research on myopia management. My poster detailed findings from my bachelor’s thesis, specifically focusing on the short-term effects of myopia management lenses using the peripheral defocus theory and their influence on choroidal thickness.
In the study, we observed that within just 60 minutes of wearing the lenses, the choroidal thickness increased slightly in the defocused eye. This observation aligns with existing literature, suggesting that changes in choroidal thickness play a significant role in myopia development. The conference featured many discussions and posters on the choroid, signaling a growing interest in this area. I anticipate that more studies will soon emerge, further exploring the role of choroidal thickness in myopia progression.
Myopia is a multifactorial condition, with both genetic and environmental influences. While genetics can predispose children to myopia, especially when both parents have high myopia, the conference also emphasized the increasing importance of environmental factors. Lifestyle changes in younger generations, such as spending less time outdoors and increased screen time on tablets and smartphones, are contributing to the rise in myopia incidence. I believe that academic pressures, combined with the pervasive use of electronic devices, especially in young children, play a major role. It’s becoming harder for children to avoid these habits, given the social pressure to conform to peer behaviors.
Experts at the conference stressed the importance of outdoor activities—at least two hours a day—and ensuring proper lighting at home, especially during reading activities. These recommendations are crucial for controlling myopia progression.
Hearing from experts in China was particularly insightful, as the country has significantly higher rates of myopia than Europe. In Asia, myopia management is an integral part of everyday practice, and their contributions to myopia research are substantial. I’m pleased to see that Switzerland is also increasing its awareness around myopia management. Recently, Swiss healthcare has recognized the importance of addressing myopia progression, and children with abnormal myopia progression are now eligible for 850 CHF in reimbursement for myopia management therapies, including specialized glasses or contact lenses.
The 19th IMC in China was an invaluable experience. The conference was exceptionally well organized, and beyond the networking and learning opportunities, I enjoyed a few days of Sanya’s tropical climate and beaches. Sharing knowledge and experiences with peers from around the world underscored the importance of collaboration—not only to advance research but also to improve patient care. I’m eager to apply the insights I gained to my practice and continue contributing to the field of myopia management.
