The influence of cycloplegic in objective refraction [PDF]

open access: yes, 2005
The purpose of this study was to compare refractions measured with an autorefractor and retinoscopy in cycloplegic and non-cycloplegic eyes. The objective refractions were performed in 199 right eyes from 199 healthy young adults with a mean age of 21.6

Identification of ocular refraction based on deep learning algorithm as a novel retinoscopy method

open access: yesBioMedical Engineering OnLine, 2022
Background The evaluation of refraction is indispensable in ophthalmic clinics, generally requiring a refractor or retinoscopy under cycloplegia. Retinal fundus photographs (RFPs) supply a wealth of information related to the human eye and might provide ...
