Spectacle correction of heterophoria in hyperopic amblyopic children
Objective: To test the effects of corrective spectacles in hyperopic amblyopic children with heterophoria. Methods: Visual acuity, refraction and the amount of heterophoria on near (33 cm) fixation were measured before and after 3 weeks of spectacle-wearing in 30 hyperopic amblyopic children with heterophoria. The control group consisted of 20 emmetropic children age-matched to the patients. Re...
متن کاملHeterophoria in young adults with emmetropia and myopia.
The purpose of this study was to investigate the relationship between heterophoria and refractive error. Thirty-six subjects (11 myopes, 25 emmetropes) participated in this study. Heterophoria was measured with the Free-Space Phoria Card at five different viewing distances (25cm, 33cm, 50cm, 100cm and 300cm). Regardless of the types of heterophoria, the amount of heterophoria reduced towards or...

BACKGROUND/PURPOSE To assess the distribution of near point of convergence (NPC), near heterophoria, and near vergence among myopic school children in South Korea. METHODS One hundred and thirty-six elementary school children, aged 8-13 years, were each given a thorough eye examination including binocular vision testing, NPC using standard push-up technique, horizontal heterophoria measuremen...

متن کاملObjective Measurement of Fusional Vergence Ranges and Heterophoria in Infants and Preschool Children
PURPOSE Binocular alignment typically includes motor fusion compensating for heterophoria. This study evaluated heterophoria and then accommodation and vergence responses during measurement of fusional ranges in infants and preschoolers. METHODS Purkinje image eye tracking and eccentric photorefraction (MCS PowerRefractor) were used to record the eye alignment and accommodation of uncorrected...
