Axial elongation following prolonged near work in myopes and emmetropes.
BACKGROUND/AIMS To investigate the influence of a period of sustained near work upon axial length in groups of emmetropes (EMM) and myopes. METHODS Forty young adult subjects (20 myopes and 20 emmetropes) were recruited for the study. Myopes were further classified as early onset (EOM), late onset (LOM), stable (SM) or progressing (PM) subgroups. Axial length was measured with the IOLMaster i...
متن کاملAxial length and choroidal thickness changes accompanying prolonged accommodation in myopes and emmetropes
The time course of elongation and recovery of axial length associated with a 30min accommodative task was studied using optical low coherence reflectometry in a population of young adult myopic (n=37) and emmetropic (n=22) subjects. Ten of the 59 subjects were excluded from analysis either due to inconsistent accommodative response, or incomplete anterior biometry data. Those subjects with vali...
متن کاملAxial elongation associated with biomechanical factors during near work.
PURPOSE To investigate the changes occurring in the axial length, choroidal thickness, and anterior biometrics of the eye during a 10-minute near task performed in downward gaze. METHODS Twenty young adult subjects (10 emmetropes and 10 myopes) participated in this study. To measure ocular biometrics in downward gaze, an optical biometer was inclined on a custom-built height- and tilt-adjusta...
متن کاملEye elongation during accommodation in humans: differences between emmetropes and myopes.
PURPOSE The pathophysiology and pathogenesis of myopia are still a matter of controversy. Exaggerated longitudinal eye growth is assumed to play an important role in the development of myopia. A significant correlation between refraction and amount of near-work has been reported. However, current knowledge of changes of axial eye length with accommodation is limited because clinical ultrasound ...
متن کاملAxial length changes with shifts of gaze direction in myopes and emmetropes.
PURPOSE The purpose of the study was to investigate the changes in axial length occurring with shifts in gaze direction. METHODS Axial length measurements were obtained from the left eye of 30 young adults (10 emmetropes, 10 low myopes, and 10 moderate myopes) through a rotating prism with 15° deviation, along the foveal axis, using a noncontact optical biometer in each of the nine different ...
