PURPOSE To describe the relation between magnitude of anisometropia and interocular acuity difference (IAD), stereoacuity (SA), and the presence of amblyopia in school-aged members of a Native American tribe with a high prevalence of astigmatism. METHODS Refractive error (cycloplegic autorefraction confirmed by retinoscopy), best corrected monocular visual acuity (VA; Early Treatment Diabetic...

PURPOSE To investigate the relationship between higher-order aberrations (HOAs) and amblyopia treatment in children with hyperopic anisometropic amblyopia. METHODS The medical records of hyperopic amblyopia patients with both spherical anisometropia of 1.00 diopter (D) or more and astigmatic anisometropia of less than 1.00 D were reviewed retrospectively. Based on the results of the amblyopia...

To determine the prevalence and type of anisometropia among school going children to study association degree with severity amblyopia. A hospital based cross-sectional carried on 500 up 10th grade (Age group:- 5 years 16 years) selected by non-probability convenient sampling according inclusion exclusion criteria. The clinical profile these was evaluated in department ophthalmology, P.D.U Govt....

Purpose: To investigate ocular asymmetry status 5 years after cranioplasty in children with unilateral coronal craniosynostosis.Methods: The medical records of 41 who underwent at a mean age 11.7 months were retrospectively reviewed. cranial vault index (CVAI) and the amount head tilt measured on images obtained before cranioplasty. Presence anisometropia, aniso-astigmatism, amblyopia, strabism...

PURPOSE To investigate whether photorefractive keratectomy (PRK) performed in infant primates can modify emmetropization and therefore could be used to study mechanisms of refractive error development. METHODS Six healthy rhesus monkeys ranging in age from 2 to 3 months were randomly divided into two groups (n = 3 each). Anisometropia was induced in each animal by performing PRK on one eye. H...

PURPOSE Anisometropia is a common cause of amblyopia. The relationship between anisometropia, patient age, and the development of amblyopia is unknown. Photoscreening identifies children with anisometropia in a manner that is not biased by visual acuity and allows a unique opportunity to evaluate how patient age influences the prevalence and depth of anisometropic amblyopia. METHODS A statewi...

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 refrac...
