PURPOSE To determine whether fixation instability contributes to reduced visual acuity in amblyopia, we compared fixation instability, quantified by the Nidek MP-1 microperimeter, in amblyopic and nonamblyopic children. METHODS Participants were 89 children (5-17 years old) with strabismus (n = 31), anisometropia (n = 29), or both conditions (n = 29). Fixation instability was measured using t...

Perceptual learning is considered a potential treatment for amblyopia even in adult patients who have progressed beyond the critical period of visual development because adult amblyopes retain sufficient visual plasticity. When perceptual learning is performed with the correction of high-order aberrations (HOAs), a greater degree of neural plasticity is present in normal adults and those with h...

PURPOSE This study was conducted to investigate the role of the pattern visual evoked potential (pVEP) as a predictor of occlusion therapy for patients with strabismic, anisometropic, and isometropic amblyopia. The secondary aim was to compare the characteristics of pVEP between strabismic and anisometropic amblyopia. METHODS This retrospective comparative case series included 120 patients wh...

To review a case with isoametropic, accomodative esotropic amblyopia and congenital posterior polar cataract. A 12 years old child with visual acuities 2/10 7/10, refractive error +9,00/ +7,00 and congenital cataract was observed previously for 5 years until the visual acuity of the right eye dropped 2 lines due to cataract in the more amblyopic eye. At first more amblyopic eye was operated and...

Amblyopia is an illness with reduced vision and a number of students are affected with this disease. To determine any association of amblyopia with educational activities, sport and social activities of students involved by amblyopia, this study was carried on. This study was conducted at Boali Hospital in Gazvin, Iran: A total of 110 patients 9 to 15 years (54.5% female and 45.5% male; mean ag...

The diagnosis has been made and confirmed: amblyopia. But what exactly does it mean to the parent and child who are most likely hearing it for the first time? Essentially nothing until the time is taken by us, ophthalmic medical personnel, to adequately explain the condition, the treatment options available, the goals for treatment, and the prognosis. How does one educate parents and children a...

Objective. To ascertain if parents are familiar with current recommendations on pediatric vision screening and to assess their knowledge of the roles that pediatricians, ophthalmologists and optometrists have in this screening process. Methods. A survey was targeted at parents to determine what the general public understands regarding vision screening. Results. The survey was conducted from Jan...

INTRODUCTION Refractive error is a common cause of amblyopia. OBJECTIVE To determine prevalence of amblyopia and the pattern and the types of refractive error in children with amblyopia in a tertiary eye hospital of Nepal. MATERIALS AND METHODS A retrospective chart review of children diagnosed with amblyopia in the Nepal Eye Hospital (NEH) from July 2006 to June 2011 was conducted. Childre...

PURPOSE Detection of amblyopia in infants and toddlers is difficult because the current clinical standard for this age group, fixation preference, is inaccurate. Although grating acuity represents an alternative, studies of preschoolers and schoolchildren report that it is not equivalent to the gold standard optotype acuity. Here, we examine whether the Teller Acuity Cards (TAC) can detect ambl...

We report a child who had implantation of an iris-fixated Artisan phakic intraocular lens (IOL) to correct high unilateral myopia to support the therapy of anisometropic amblyopia. After IOL implantation, the patient continued occlusion therapy to further treat the amblyopic eye. One year postoperatively, the best corrected visual acuity in the amblyopic eye was 1.00 and binocular stereovision ...
