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

BioMedical 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 ...

Prediction of cycloplegic refraction for noninvasive screening of children for refractive error.

PLoS ONE, 2021
Detection of refractive error in children is crucial to avoid amblyopia and its impact on quality of life. We here performed a retrospective study in order to develop prediction models for spherical and cylinder refraction in children.
