Effect of Day Length on Eye Growth, Myopia Progression, and Change of Corneal Power in Myopic Children

Objective Because of the northern location of Denmark, the length of the day over the year varies from 7 to 17.5 hours. Experimental and clinical results suggest that the development of myopia may be related to ambient light exposure. The purpose of current study was to investigate whether axial eye...

Zusammenfassung:	Objective Because of the northern location of Denmark, the length of the day over the year varies from 7 to 17.5 hours. Experimental and clinical results suggest that the development of myopia may be related to ambient light exposure. The purpose of current study was to investigate whether axial eye growth, myopia progression, or corneal power change in Danish myopic children varies with the length of the day. Design Cross-sectional study. Participants Two hundred thirty-five children 8 to 14 years of age found to have myopia during screening for a clinical trial ( ClinicalTrial.gov identifier, NCT00263471 ; accessed December 6, 2005). All children found to have any value of spherical equivalent that was myopic (
