The objective of the project will have to cover different areas that represent research pillars: optical devices used in the project, optical quality of the eye and accommodative response
, psychophysics of visual function, subjective quality of vision, perceptual factors that affect the quality of vision.
These four components, along with modulation from the pupil, interact nonlinearly to produce the overall dynamic and static accommodative response profile, with disparity and blur being the two primary drives under normal binocular-viewing conditions in visually normal individuals [1,4-6].
This is diagnosed when a patient exhibits a slowed accommodative response (i.
Heyman, OD, FAAO, FCOVD; assistant professor at the Southern California College of Optometry and author of the article, Accommodative Response
in Children with Visual Impairment, finds it is necessary to consider using dynamic near retinoscopy to assess each patient's accommodative response
prior to prescribing near addition lenses.
The most accommodative response
is corrective actions and an apology, but this can only be used when there are no financial concerns.
On the other side of the coin, a bargaining strategy involves an attempt to attain an explicit and concurrent exchange through negotiations, whereas the strategy of reciprocity is based on an expectation that the offering of an inducement will eventually encourage an opponent to reciprocate through a more accommodative response
The minimum plus which renders a normal accommodative response
might be a useful starting prescription to consider.
Lastly, tonic accommodation refers to the default accommodative response
in the absence of blur, disparity, and proximal stimuli.
The fact that the children fitted with DF contact lenses showed normal accommodative responses
suggests that it is the sustained myopic de-focus in the central and peripheral retina during both distance and near viewing that is responsible for the reduction in progression of axial myopia and not changes in accommodative lag.
, which include full apologies and corrective action, are characterized by the organization taking full or substantial responsibility for the failure, and a sincere willingness to repair the damage done.
, including both monocular and binocular accommodative amplitude, accommodative convergence to accommodation ratio, and negative and positive relative accommodation, were reduced in the TBI population compared with normative values.
Recent studies have shown that the majority of children with Down's syndrome (10) and cerebral palsy (11) have defective accommodative responses
, even when distance refractive errors are fully corrected.
