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

open access: yesPLoS 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.

Refractive errors in premature infants with retinopathy of prematurity after anti-vascular endothelial growth factor (anti-VEGF) therapy [PDF]

open access: yesVojnosanitetski Pregled, 2017
Background/Aim. Retinopathy of prematurity (ROP) is a vasoproliferative retinopathy which affects the blood vessels of the retina during its development. The aim of this study was to evaluate the incidence and the degree of refractive errors in premature

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 ...
