AIM To identify which factors influence the final visual acuity in children with anisometropic amblyopia. METHODS A retrospective analysis of 112 children with anisometropic amblyopia, identified from examining all case notes of children who had failed preschool or school screening. RESULTS The age at presentation had no effect on the final visual outcome (p=0.804). Both the degree of refra...

PURPOSE To investigate the association between ocular dominance (sighting dominance) and refractive asymmetry in phakic patients. METHODS This retrospective study included 3,012 patients with a mean age of 29.0 ± 5.3 years (range: 20 to 39 years). Refractive error was determined with cycloplegic refraction and axial length was determined with IOLMaster (Carl Zeiss Meditec, Dublin, CA). Ocular...

PURPOSE To analyze the causes of anisometropia. METHODS Between June 2011 and November 2012 101 participants were divided into three groups. The refraction comprising the degree of refractive errors in the presence of astigmatism which was converted into the degree of spherical equivalent as well as ocular axial length (AL), corneal curvature (CR), average corneal power (ave K) and diopters w...

We report a case of one sister and brother with mirror image myopic anisometropia. One sister and brother complained visual disturbance. The sister was 10 years 11 months old, and brother was 8 years 4 months old. Full ophthalmic examinations were performed, including slit lamp examination, intraocular pressure, keratometry, anterior chamber depth, axial length, fundus examination and the cyclo...

PURPOSE To evaluate the efficacy of unilateral photorefractive keratectomy to correct anisometropia induced by retinal detachment surgery. METHODS Photorefractive keratectomy was performed in 10 eyes of 10 patients with anisometropia induced by previous retinal detachment surgery. The Aesculap Meditec MEL 60 excimer laser was used. RESULTS Preoperative mean spherical equivalent refraction w...

METHODS. We measured the covariation between these four abilities in children 4 to 9 years of age (n1⁄472) with strabismus, anisometropia, or mixed strabismus/anisometropia, and unaffected controls. Children reported the orientation of a target (a modified ‘‘Pac-Man,’’ similar to Landolt-C stimuli) using four ‘‘ghosts’’ as references. Using a modified staircase procedure we measured threshold s...

The refractions of 1648 children aged 11 to 13 months are reported. Atropine 1% was used for cycloplegia. 11.83% of the children had bilateral hypermetropia of +2.00 or more D. 13.23% of them had +1.50 or more D astigmatism in one or both eyes, and 6.5% had anisometropia. Anisometropia was significantly (P=0.000 001%) associated with bilateral hypermetropia, but even more significantly (P=0.000...

Introduction: Traditional therapy for anisometropic amblyopia often fails when severe anisometropia is present. Recent advances in refractive surgery for anisometropic amblyopia suggest that surgical treatment may be a viable alternative in certain situations. Methods: The potential indications for refractive surgery for anisometropia, the different refractive procedures available, and the risk...

Background: To determine the association between ocular dominance and myopic anisometropia in Chinese myopic subjects. This relevance would facilitate to identify the ocular dominance in bilateral cataract patients. Design: Retrospectively case study. Participants: 1503 Chinese myopic subjects, mean age 27 years, who were candidates for corneal myopic refractive surgery were reviewed between 20...

PURPOSE In uncorrected anisometropia, protracted dichoptic stimulation may result in interocular inhibition, which may be a contributing factor in amblyopia development. This study investigates the relationship between interocular interactions and anisometropic amblyopia. METHODS Three visual functions (low-contrast acuity, contrast sensitivity, and alignment sensitivity) were measured in the...
