Myopia Stabilization and Associated Factors
Among Participants in the Correction of Myopia Evaluation Trial (COMET) 2013 於IOVS發表的COMET cohort研究結果:
Age at Stabilization
Based on the Gompertz curve–based
estimates, approximately half (48%; 203 of 426) of the overall COMET cohort had
stable myopia (estimated SER within 0.50 D of the asymptote) by age 15 years.
The proportion with estimated stable myopia increased to 77% (330 of 426) by
age 18 years and to 90% (384 of 426) by age 21 years. By age 24 years, the
curves of almost all of the cohort (96%; 411 of 426) had achieved the
curve-based definition of myopia stabilization
.
近視穩定年紀48%在15歲達到穩定,77%在18歲達到穩定,90%在21歲達到穩定,96%在24歲達到穩定,平均在15.61歲達到近視穩定,在達到近視穩定前四年開始減速,平均在11.95歲達到近視開始減速成長的年齡(亦即近視成長速度的高峰)。穩定時的近視度數平均為487度,最終平均近視度數為537度(依該研究的近視穩定的定義兩者之間相差50度)。
方法:收集6~12歲之間,近視在125~450度之間,共469位小朋友,追蹤至少6年。
討論:近視成長的過程,各年齡階段的成長速度並不一樣,且不同的種族達到穩定的年紀有所差異。
