Myopia

The main experimental work of this thesis has been a cross-sectional study of the prevalence of refractive error and its biometric correlates in Middle Eastern adults. In addition dynamic accommodative responses and twenty-four hour axial length fluctuations were investigated in…

This thesis has investigated nearwork-induced transient myopia and accommodation responses in relation to refractive stability, multichromatic stimuli and orthokeratology. Five individual studies have been carried out. Initially an investigation into the temporal and dioptric as…

The objective of the present studies was to assess whether there were predictable differences in the thickness of the human cornea in relation to stable manifest refractive error using a scanning slit optical topography method (Orbscan II).
