The Effect of Cycloplegia on Ocular Alignment and AC/A Ratio

Journal of Ophthalmic & Vision Research
Purpose: The present study sets out to investigate the effect of cyclopentolate-induced cycloplegia on distance and near deviation and the accommodative convergence/accommodation (AC/A) ratio. Methods: This prospective study was performed on 30 subjects.

Comparison of Different Cycloplegic Refraction Regimens for Children

Majalah Kedokteran Bandung
In the process of a pediatric eye exam, cycloplegic refraction is a crucial step. Since no single cycloplegic drug is ideal, a combination regimen is employed.

Approach to cycloplegic refraction

Canadian Journal of Optometry
Children and younger adults are able to overcome some of the challenges posed by uncorrected refractive errors due to their potent accommodative abilities. However, this potent accommodative ability can significantly affect the precision of their refractive error’s assessment. To overcome this, paediatric cycloplegic refraction becomes indispensable as

Assumption-free estimation of the genetic contribution to refractive error across childhood [PDF]

, 2015
Purpose: Studies in relatives have generally yielded high heritability estimates for refractive error: twins 75–90%, families 15–70%. However, because related individuals often share a common environment, these estimates are inflated (via misallocation ...

Effectiveness of cyclopentolate 1% compared to the combination of cyclopentolate 1%, tropicamide 1%, and phenylephrine 10% in cycloplegic refractive examination

Journal of Clinical Ophthalmology and Research
Context: Refractive errors in children require appropriate eyeglass correction. Cycloplegic refraction is a method used to determine eyeglass prescriptions in children due to their high accommodative power.

Difference Between Cycloplegic and Non-Cycloplegic Refraction and Its Association with Longitudinal Refractive Changes in Chinese Children

Ophthalmic Epidemiology
To investigate the difference between cycloplegic and non-cycloplegic spherical equivalent refraction (DSE) as well as the association between baseline DSE and future refractive changes in Chinese children. We retrospectively reviewed the medical records of children aged 2–8 years who underwent auto-refraction at the Zhongshan Ophthalmic Center ...
