The Quest for the Human Ocular Accommodation Mechanism [PDF]
Acta Ophthalmologica, 2020 AbstractWe have known the accommodation phenomenon since 400 BC. Hypotheses about its mechanisms varied widely for two millennia. Early in the 17th century, when people became more aware of ophthalmic optics, Scheiner and Descartes were close to solving that accommodation worked by changes in the lens. Others rejected their idea, and people even denied

Neural Control of Vergence and Ocular Accommodation. [PDF]
Annu Rev Vis SciWe review the current state of our knowledge of the neural control of vergence and ocular accommodation in primates including humans. We first describe the critical need for these behaviors for viewing in a three-dimensional world. We then consider the sensory stimuli that drive vergence eye movements and lens accommodation and describe models of the ...

Changes of Ocular Aberration With Accommodation
American Journal of Ophthalmology, 2002 To study the effect of accommodation on ocular aberrations.Observational case series.The ocular aberrations in 33 eyes of 33 young adults were measured with a Hartmann-Shack wavefront aberrometer before and during 3 diopters of accommodation.The root mean square values of wavefront error did not change for a 4-mm and a 6-mm zone; however, spherical ...

Ocular Alignment and Strabismus-Related Findings Associated with Low-Dose Atropine for Myopia Control in Children: A Structured Narrative Review [PDF]
ChildrenBackground/Objectives: Low-dose atropine eye drops are widely used to slow myopia progression in children, but by reducing accommodation they may affect near ocular alignment and binocular visual function.
