PURPOSE: Strabismus and anisometropia are the most common causes of amblyopia. It can be easily prevented or treated if detected early. With the changing socio-cultural-economic milieu of the society, the perspectives of strabismus in society are gradually changing but still adequate knowledge, awareness, and attitude of parents toward strabismus will help in preventing amblyopia and aid in the proper psychosocial adaptation of such children. This study aimed to assess knowledge and attitude of parents toward children suffering from strabismus...

REVIEW
Stephen J Vincent
Ocular pathology that manifests at an early age has the potential to alter the vision-dependent emmetropisation mechanism, which co-ordinates ocular growth throughout childhood. The disruption of this feedback mechanism in children with congenital or early-onset visual impairment often results in the development of significant ametropia, including high levels of spherical refractive error, astigmatism and anisometropia. This review examines the use of contact lenses as a refractive correction, low vision aid and therapeutic intervention in the rehabilitation of patients with bilateral, irreversible visual loss due to congenital ocular disease...

The authors present a case report of a three-year-old female patient with bilateral multiple anterior vitreous cysts. During examination for intermittent esotropia of the right eye was diagnosed not only hypermetropia, astigmatism and anisometropia, but also pigmented changes in peripheral retrolental space of both eyes. Clinical examination under general anaesthesia revealed bilateral multiple pigmented immobile vitreous cysts. There were five almost spherical, translucent, but slightly pigmented cysts on its cover on the right eye and four similar on the left, but visible only with dilated pupils...

Lasik is a common surgery for treating anisometropia. In this study, we asked a specific question: what's the effect of Lasik surgery on anisometropes' sensory eye dominance ? Fifteen myopic anisometropes (mean age: 23 ± 6.9 years old; 6 females) participated in our experiment. We quantitatively measured participants' sensory eye dominance before and after the Lasik surgery using a binocular phase combination paradigm. We found no significant change of sensory eye dominance within 16 weeks (measured between 8 to 96 days, for one or two repetitions) after the surgery (t(14) = -1...

INTRODUCTION: Severe myopic anisometropia has been identified to have heritability, but the pathogenesis of anisometropia still remains obscure. CASE DESCRIPTION: Here, we presented a Chinese severe myopic anisometropia family with 5 members affected. Though using the exome sequencing, we identified a novel mutation in the UNC5D gene (c.1297C>T, p.R433C), which was predicted to have a damage effect on the protein function and kept highly conserved throughout evolution across species...

BACKGROUND: Posterior polymorphous corneal dystrophy (PPCD) is typically considered bilateral and asymptomatic. However, few case reports on patients with unilateral PPCD with asymmetric refractive error have mentioned anisometropic amblyopia development. In support of this, we report 3 cases of unilateral PPCD that presented as anisometropic astigmatism. Visual prognosis related to amblyopia development is discussed. CASE PRESENTATION: All 3 patients had a band lesion in the affected eye and a difference of at least 1...

Purpose: Previously, we have mapped amblyopic eye suppression within the central 20° of the visual field and observed a gradient of suppression that is strongest in central vision and weakens with increasing eccentricity. In this study, using a large dichoptic display, we extend our novel suppression mapping approach further into the periphery (from 20°-60°) to assess whether suppression continues to decline with eccentricity or plateaus. Methods: Sixteen participants with amblyopia (10 with strabismus, 6 with anisometropia without strabismus; mean age: 37...

The theme of the 2016 Burian Lecture is how our understanding of strabismus has been changed by the research carried out in our laboratory in Reading over the years. Accommodation and convergence are fundamental to orthoptics, but actual responses have often been very different compared to what we had expected. This paper outlines how our laboratory's understanding of common issues such as normal development of accommodation and convergence, their linkage, intermittent strabismus, anisometropia, orthoptic exercises, and risk factors for strabismus have changed...
