Identifying the link between pediatric nearsightedness and choroid...Early diagnosis and prevention of high myopia
Jan 12, 2025
An ophthalmology team at Seoul Boramae Hospital, operated by Seoul National University Hospital, has established a new turning point in myopia management by identifying the link between pediatric myopia progression and choroid thickness changes. Professor Chung Ho-kyung, Professor Lee Jung-heon, Professor Ahn Ji-yoon, Professor Shin Joo-young, Professor Lee Kyung-min, Professor Oh So-hee, Professor Kim Marda of Dongguk University Ilsan Hospital, and Director Kim Seok-hwan of The One Seoul Eye Department participated in the study.
Myopia has a particularly high prevalence in East Asia and is attracting attention as a major ophthalmic problem in Korea. This study is one of the first to identify the specific pattern and timing of choroidal thickness changes in the progression of childhood myopia for a long period of time, and is of great significance in that it suggested the possibility of early diagnosis and prevention of high myopia.
The research team confirmed a pattern in which the choroid thickness was maintained in the early myopia stage and the thickness decreased in the high myopia stage. This clearly reveals the dynamic relationship between myopia progression and choroidal changes through long-term observation, unlike previous studies that were only fragmented and short-term observations.
The study was part of the Boramae Myopia Cohort Study, a long-term project at Boramae Hospital, and was conducted over four years on 23 healthy children. The researchers measured children's refractive index, intraocular field, and choroid thickness every two years and analyzed changes occurring during the myopia process.
As a result of the study, the subjects' myopia progressed by an average of -4.41 diopters over a four-year period. During the first two years, the choroid thickness did not change significantly, but the choroid thickness decreased in children who progressed rapidly over the next two years. On the other hand, children with stable myopia showed little change in choroid thickness.
Professor Jiyoon Ahn "This study provides an important clue to prevent the progression to high myopia by identifying the timing of choroidal changes in the course of myopia."We will continue to conduct follow-up studies that will contribute to increasing the efficiency of myopia management programs in the future."
The results of this study suggest new directions for myopia management and treatment, and are evaluated as providing basic data for early diagnosis and prevention of high myopia.
