Amblyopia is much more than decreased vision, it is a syndrome. The variety of deficits is a result of structural and functional differences in the visual pathway from the retina to the cortex. Historically, it was thought that amblyopia did not cause a relative afferent pupillary defect, but recent studies suggest otherwise. Research into the thalamic and cortical influences on the pupillary p...

AIMS A prospective study of the efficacy of amblyopia treatment in preschool children has recently been called for, requiring an untreated control group. The present study assessed data from patients with amblyopia untreated owing to lack of compliance, or with amblyopia risk factors, to determine outcome. METHODS Longitudinal data were obtained from 18 4-6 year old patients who had initially...

All the examinations were performed in schools. All students received refraction, vision and subjective refraction tests. The cover test was...

PURPOSE To identify factors that influence the outcome of treatment for unilateral amblyopia, as a part of the Monitored Occlusion Treatment of Amblyopia Study (MOTAS). METHODS This was an intervention study consisting of three nonoverlapping phases: "Baseline", "refractive adaptation" (18 weeks of full-time spectacle wear), and "occlusion" (6 hours of patching per day, objectively monitored)...

Abstract Objectives To assess parents’ perceptions about amblyopia and its causes, symptoms, risk factors, treatments, the importance of follow-up to evaluate their awareness regarding consequences critical complications. Results Parents or companions (n = 401) were surveyed, 52.9% mothers, 81.8% mothers 85.7% fathers highly educated (diploma, college university degree), 58 (14.5%) had a child ...

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...

PURPOSE To investigate, using optical coherence tomography (OCT), whether retinal nerve fiber layer thickness (RNFLT) is affected in amblyopic eyes. METHODS Using OCT (Stratus OCT™ [Carl Zeiss, Dublin, CA]), the RNFLT was measured in 26 patients with persistent unilateral amblyopia and in 25 patients with recovered unilateral amblyopia. The RNFLT was compared between the affected and fellow e...

BACKGROUND Amblyopia is an acquired defect of vision caused by abnormal visual experience that occurs during childhood. Since early diagnosis is important in preventing further irreparable effects, the aim of this study was to investigate the outcome of amblyopia screening in children. METHODS Data from the amblyopia screening program in the Welfare Department of Bandar Abbas during 2011-2012...

background: amblyopia is considered as one of the most prevalent vision problems in pediatrics age (1-5%). recently, new methods in amblyopia treatment were reported in amblyopia treatment study (ats’).the objective of this study was to recognize amblyopia treatment knowledge of iranian ophthalmologists and optometrists which are responsible for amblyopia treatment in our and other countries. m...
