Amblyopia is a common visual impairment in developing countries and a major but neglected health issue. Definite diagnosis in children is difficult due to lower cooperation in this age range. Electroretinography (ERG) may be a useful objective method for diagnosis of amblyopia. In this study, we compare the ERG findings in amblyopic and non-amblyopic children. It is concluded that ERG is a sensitive and objective diagnostic test for amblyopia. It is recommended that ERG be used as a quick tool for diagnosis of amblyopia in children.

Factors Affecting Surgical Success Rates in Pediatric Horizontal Strabismus Surgery.
Cureus
November 2024
Department of Ophthalmology, Adiyaman University Faculty of Medicine, Adiyaman, TUR.
Introduction: Horizontal strabismus is a binocular alignment disorder that can lead to significant complications in childhood, such as visual impairment and amblyopia. This study aimed to evaluate the success rates of horizontal strabismus surgery in pediatric patients and to identify the factors affecting surgical outcomes. Specifically, it examined the relationship between surgical success and factors such as age, deviation angle, and amblyopia in pediatric horizontal strabismus cases.

Purpose: The aim of this study was to investigate changes in the light-adapted (LA) electroretinogram (ERG) associated with paediatric amblyopia.
Method: A total of 220 eyes from 81 postoperative paediatric cataract patients and 29 healthy children were enrolled in four groups, namely controls, unilaterally amblyopic eyes, non-amblyopic fellow eyes and bilaterally affected eyes. Differences in LA ERG variables (peak time and amplitude of a- and b-waves and photopic negative response [PhNR]) were compared across groups, as well as their associations with visual acuity and changes in axial length.
Fine Motor Skills, Reading Speed, and Self-Reported Quality of Life in Adults With Amblyopia and/or Strabismus.

Centre for Vision and Eye Research, Faculty of Health, Queensland University of Technology, Brisbane, Queensland, Australia.
Purpose: The purpose of this study was to assess fine motor skills and reading proficiency in adults with amblyopia and/or strabismus, and to determine how these relate to clinical measures of vision and self-reported vision-related quality of life.
Methods: Fine motor skills (Manual dexterity - Bruininks-Oseretsky Test of Motor Proficiency [BOT-2]) and reading performance (International Reading Speed Texts [IReST]) were assessed in 23 adults with non-strabismic amblyopia, 20 with non-amblyopic strabismus, 52 with both amblyopia and strabismus, and 19 with normal visual development. Visual acuity and binocular function score (BFS), obtained from stereoacuity and presence/absence of suppression, were also determined.
Comparison of Cambridge vision stimulator (CAM) therapy with passive occlusion therapy in the management of unilateral amblyopia; a randomized clinical trial.
Strabismus
September 2024
Department of Optometry and Vision Sciences, University of Melbourne, Melbourne, Australia.
Introduction: There are limited studies on the effectiveness of Cambridge vision stimulator (CAM) therapy as a management strategy in amblyopic patients. In addition, all these studies have a low sample size. The main purpose of this study was to compare the effect of CAM therapy with passive occlusion therapy in the management of unilateral amblyopia.

Purpose: To compare the demographic and ocular characteristics of patients with low and high levels of anisometropia compared with non-anisometropic individuals.
Methods: This cross-sectional study was conducted on 1803 individuals (age range, 1 to 30 years) examined at strabismus clinics between January 2019 and December 2020. Of these, 203 subjects had anisometropia (11.
