Myopia is on the rise globally, and has been more so since the COVID-19 pandemic. The burden has been felt most strongly in East Asia, where rates can be as high as 90% and over. In the US and Europe, rates are still below 50%, but are projected to rise above that threshold by 2050. Childhood myopia can lead to severe consequences later in life, with a high number of individuals suffering from vision impairment due to pathologic myopia.

In this video, Gemmy Cheung, MD, PhD, and Timothy Lai, MD, FRCOphth, discuss this topic.
