Importance: Occlusion dose monitors have helped establish that better adherence to occlusion is associated with improved visual outcomes in patients undergoing amblyopia treatment. However, the role of adherence to glasses wearing is unknown. Objectives: To establish the feasibility and reliability of objectively monitoring adherence to glasses wearing using age-based norms, establish the association between adherence to glasses wearing and improvement in visual acuity (VA) after optical treatment and occlusion therapy, and analyze the effect of age, sex, refractive errors, type of amblyopia, and adherence to glasses wearing on improvement in VA...

This systematic review and meta-analysis is to evaluate the risk of development of concomitant strabismus due to refractive errors. Eligible studies published from 1946 to April 1, 2016 were identified from MEDLINE and EMBASE that evaluated any kinds of refractive errors (myopia, hyperopia, astigmatism and anisometropia) as an independent factor for concomitant exotropia and concomitant esotropia. Totally 5065 published records were retrieved for screening, 157 of them eligible for detailed evaluation. Finally 7 population-based studies involving 23,541 study subjects met our criteria for meta-analysis...

Purpose: Do humans with uncorrected anisometropia who have not developed anisometropic amblyopia exhibit a shift in ocular dominance nonetheless, reflecting a more subtle form of deprivation? Also, is such a change in dominance, if it occurs, permanent or could it be rectified by an extended period of optical correction? Methods: A total of 25 normal controls (27.5 ± 2.1 years; mean ± SD); 28 anisometropes (20.7 ± 5.6 years) who were fully corrected for more than 16 weeks prior to this investigation; and 24 anisometropes who had never been corrected (21...

Unicoronal craniosynostosis predisposes to ophthalmologic abnormalities such as strabismus, astigmatism, and amblyopia. The authors explored the ophthalmologic outcomes following fronto-orbital advancement (FOA). A systematic search of PubMed, Embase, and the Cochrane Library was conducted. Included studies reported postoperative rates of strabismus, astigmatism, and/or amblyopia. Two independent reviewers performed screening and extracted data including preoperative rates, laterality and severity of findings, need for ocular surgery, and timing of FOA...

In this paper, some typical excessive medical problems in the treatment of common eye diseases in children were listed as follows: unnecessary examinations carried out for children with little or no corresponding complaints; prescription for spectacles for physiological hyperopia or astigmatism in children; over-diagnosis, over-or nonstandard-treatment for amblyopia; strabismus surgeries performed in children with esotropia but without full optical correction of hyperopic refractive error, in children with monocular strabismus and amblyopia but without standard cover therapy, in children with intermittent exotropia but without optical correction of myopic refractive errors and myopic anisometropia, and without evaluation of their fusional control ability; exaggerated the harm of myopia and the curative effect of Orthokeratology contact lenses without considering the patient's compliance; cataract surgery performed in infants with partial opacity of the lens that has little effect on the vision...

Amblyopia is a developmental disorder of vision usually associated with the presence of strabismus and/or anisometropia during early childhood. Subject literature has shown that both the amblyopic and fellow eyes (especially in strabismic subjects) may manifest a variety of perceptual and oculomotor deficits. Previous studies using simple saccadic responses (pro-saccades) showed an increased saccadic latency only for the amblyopic eye viewing conditions. So far, there have appeared no saccadic latency studies in strabismic amblyopia for more complex volitional saccades...

BACKGROUND: We have developed a new aniseikonia testing method based on the space eikonometry (ATSE) principle. The purpose of this study was to compare aniseikonia obtained by the ATSE to that of the conventional new aniseikonia tests (NAT), which is commonly used in Japan. METHODS: Thirty normal subjects (mean age: 22.8 years) without ocular disease except for refractive errors were studied. All of the subjects had normal binocular single vision with stereopsis...

Palpebral malformations can be isolated or associated with a craniofacial disorder. Their assessment is based on clinical examination; additional investigations are mainly done to characterize craniofacial syndromes. In case of extrapalpebral lesions or complex craniofacial pathology, genetic testing must be performed. Some isolated malformations will only need a simple follow-up; others must have specific treatment, undertaken following a precise timing, taking into account child and anatomical structures' growth and the possible consequences of the malformation on the eye and child's sight (degree of urgency)...

INTRODUCTION: Stereopsis, the highest grade of binocular single vision, is affected by various factors, such as mis-alignment of visual axes, refractive errors especially anisometropia and astigmatism, both of which may result in amblyopia. There are very few studies in literature regarding the relationship between stereoacuity and refractive errors, especially astigmatism. AIM: The present study was conducted to determine the correlation between stereoacuity and experimentally induced graded astigmatism in emmetropes...
