Internal Astigmatism and Its Role in the Growth of Axial Length in School-Age Children

Internal Astigmatism and Its Role in the Growth of Axial Length in School-Age Children

Objectives. To explore the role of internal astigmatism (IA) in the growth of axial length (AL) in school-age children. Methods. Total astigmatism (TA), corneal astigmatism (CA), and AL of all children in Jing’an District 2nd Centre Primary School in Shanghai were measured. In IA, the difference bet...

Zusammenfassung:Objectives. To explore the role of internal astigmatism (IA) in the growth of axial length (AL) in school-age children. Methods. Total astigmatism (TA), corneal astigmatism (CA), and AL of all children in Jing’an District 2nd Centre Primary School in Shanghai were measured. In IA, the difference between TA and CA was also calculated using vector analysis. The association of axial length with IA, genders, and age was analyzed using linear regression. The difference of IA between both eyes was also calculated. The AL between both eyes was compared using paired samples t-test when DIA = 0 D,
