Are high lags of accommodation in myopic children due to motor deficits?
(Elsevier, 2017-01)Children with a progressing myopia exhibit an abnormal pattern of high accommodative lags coupled with high accommodative convergence (AC/A) and high accommodative adaptation. This is not predicted by the current models ... -
Binocular Adaptation to +2 D Lenses in Myopic and Emmetropic Children:
(Wolters Kluwer, 2009-06)Purpose. To compare vergence adaptation to +2 D addition lenses in myopic and emmetropic children and to evaluate the influence of the accommodative-vergence crosslink (AC/A ratio) on this adaptation. Methods. Nine ... -
Can current models of accommodation and vergence predict accommodative behavior in myopic children?
(Elsevier, 2014-08)Investigations into the progression of myopia in children have long considered the role of accommodation as a cause and solution. Myopic children show high levels of accommodative adaptation, coupled with accommodative lag ... -
Effect of heterophoria type and myopia on accommodative and vergence responses during sustained near activity in children
(Elsevier, 2012-03-15)The influence of phoria-type and myopia on changes to vergence and accommodation during prolonged near-task was examined in 53 children. Participants were classified into phoria and refractive categories based on near ... -
Effect of Intraocular Pressure on Chick Eye Geometry, Finite Element Modeling, and Myopia
(University of Waterloo, 2010-09-30)In most cases, myopia is characterized by an increase in axial length of the eye, but the exact mechanisms for the axial elongation are still unknown. Higher intraocular pressure (IOP) has been associated with myopia and ... -
Effect of near adds on the variability of accommodative response in myopic children
(Wiley, 2011-03)Purpose: Higher variability of accommodative response (VAR) has been reported in myopes and speculated to be a possible risk factor for the progression of myopia. We investigated whether near adds of +2D and −2D were capable ... -
Near addition lenses as a tool to investigate vergence adaptation in myopic children
(University of Waterloo, 2011-08-12)Accommodation and vergence are two interacting ocular motor systems that function to maintain clear and single vision across a wide range of distances. Sustained fixation results in the adaptation of these ocular motor ... -
Understanding the sensory and motor behavior of accommodation in progressive myopic children
(University of Waterloo, 2017-09-27)Introduction: Accommodation and vergence, in unison, help in maintaining a clear and single binocular vision, a linchpin for normal vision development. Under natural viewing conditions, accommodation and vergence systems ...
