Central and Peripheral Ocular High-Order Aberrations and Their Relationship with Accommodation and Refractive Error: A Review

Vision, 2023
High-order aberrations (HOAs) are optical defects that degrade the image quality. They change with factors such as pupil diameter, age, and accommodation.

Functional Neuroanatomy of the Human Accommodation Response to an “E” Target Varying from -3 to -6 Diopters

Frontiers in Integrative Neuroscience, 2020
Background: We aimed to identify the functional brain networks involved in the regulation of visual accommodation by contrasting the cortical functional areas evoked by foveal fixation to an “E” target, which were subservient to the accommodation ...

The Effect of Accommodation on Peripheral Refraction under Two Illumination Conditions

Photonics, 2022
The clinical importance of peripheral refraction as a function of accommodation has become increasingly evident in the last years with special attention given to myopia control. Low order ocular aberrations were measured with a Hartmann–Shack aberrometer

Accommodative Exercises to Lower Intraocular Pressure

Journal of Ophthalmology, 2020
Purpose. This study investigated how a conscious change in ocular accommodation affects intraocular pressure (IOP) and ocular biometrics in healthy adult volunteers of different ages. Methods. Thirty-five healthy volunteers without ocular disease or past
