光と近視：非視覚オプシンの拡大する役割に焦点を当てる

Myopia, or near-sightedness, is a growing global concern as its incidence rate continues to dramatically rise. It has been linked to significant ocular morbidity and reduced quality of life. Despite this, much is still largely unknown about the development of and the mechanisms driving the pathogenesis of myopia. As such, myopia prevention and myopia mitigation treatment strategies are occasionally ineffective, can be difficult to adhere to, and have diminishing returns over time. Recently, non-visual opsins (OPN3, OPN4, and OPN5) have emerged as potentially impacting myopia regulation. This narrative review aims to summarize the current understanding of the non-visual opsins and how they might influence myopia. In addition, this review explores how utilizing this knowledge can help develop promising future treatment strategies to reduce the incidence and severity of myopia.
