Correlation between ocular parameters and amplitude of accommodation

Indian Journal of Ophthalmology, 2010
To study the relationship between ocular parameters and amplitude of accommodation (AA) in the peri-presbyopic age group (35-50 years).Three hundred and sixteen right eyes of consecutive patients in the age group 35-50 years, who attended our outpatient clinic, were studied.

Exploring Changes in Ocular Aberrations for Different Fixation and Accommodation Stimuli

Photonics
Background: Given the lack of standardization in stimulus types for assessing accommodation, we aimed to evaluate accommodative response (AR) and Zernike coefficients using four different stimuli.

New methodology to measure the dynamics of ocular wave front aberrations during small amplitude changes of accommodation [PDF]

, 2007
We present a methodology to measure the systematic changes of aberrations induced by small changes in amplitude of accommodation. We use a method similar the one used in electrophysiology, where a periodic stimulus is presented to the eye and many ...

Changes in intraocular pressure and ocular pulse amplitude with accommodation [PDF]

British Journal of Ophthalmology, 2009
To investigate the change that occurs in intraocular pressure (IOP) and ocular pulse amplitude (OPA) with accommodation in young adult myopes and emmetropes.Fifteen progressing myopic and 17 emmetropic young adult subjects had their IOP and OPA measured using the Pascal dynamic contour tonometer.

Effect of accommodation on peripheral ocular aberrations

Journal of Vision, 2009
Changes in peripheral aberrations, particularly higher order aberrations, as a function of accommodation have received little attention. Wavefront aberrations were measured for the right eyes of 9 young adult emmetropes at 38 field positions in the central 42 x 32 degrees of the visual field. Subjects accommodated monocularly to targets at vergences of

Age-Related changes in ocular aberrations with accommodation

Journal of Vision, 2007
This study investigates the changes in aberrations with monocular accommodation as a function of age. Second-order and higher order wavefront aberrations and pupil size were measured as a function of accommodation demand over the range of 0-4 D in the right eyes of 47 normal subjects with ages between 17 and 56 years.
