Spectacle correction of heterophoria in hyperopic amblyopic children

چکیده
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. Results: Uncorrected eyes displayed hyperopic amblyopia accompanied by heterophoria. Corrective spectacles not only attenuated the hyperopia and amblyopia, but also changed the heterophoria to orthophoria. The amount of heterophoria before wearing spectacles was significantly different from that in emmetropic children; but after correction with spectacles, it was the same as that in the emmetropic controls. Conclusion: Correction with spectacles is effective for the treatment of heterophoria in hyperopic children with amblyopia.

Normal emmetropization in infants with spectacle correction for hyperopia.
PURPOSE The development of emmetropic refraction is known to be under visual control. Does partial spectacle correction of infants' refractive errors, which has been shown to have beneficial effects in reducing strabismus and amblyopia, impede emmetropization? The purpose of the present study was to perform the first longitudinal controlled trial to investigate this question in human subjects. ...
متن کاملEmmetropization in accommodative esotropia: an update and review.
Many children with accommodative esotropia are able to successfully discontinue spectacle wear, while others require spectacle correction into adulthood. Parents often ask about the likelihood of glasses being required on a long-term basis and whether use of spectacles will cause dependency. Most infants are hyperopic and gradually become emmetropic. The extent to which accommodation and specta...

Background: Recent evidence points to the use of spectacles alone in the treatment of anisometropic amblyopia. However, the impact of this treatment on the restoration of binocular vision is often not considered. Case Report: Patient M.Z., aged 7 years, showed 3.5D of anisometropia which was coupled with a best corrected visual acuity of 6/38 in the more hyperopic eye (6/6 in the non-amblyopic ...

BACKGROUND/AIM Many children with accommodative esotropia must continue spectacle use throughout life. This study was undertaken to determine which factors are predictive of successfully weaning children with accommodative esotropia out of spectacles. METHODS A retrospective review of 10 children with accommodative esotropia, who were gradually weaned from their hyperopic correction, and thre...
