The AAPOS Vision Screening Committee established the first guidelines for automated preschool vision screening in 2003. These primarily addressed the magnitude of refractive error that was (by consensus) thought to put a child at risk for the development of amblyopia. Since then, more data have emerged about the prevalence of amblyopia risk factors in young children from which it is clear that ...

We report the results of a new amblyopia treatment device used in 7 children with anisometropic amblyopia. The Occlu-pad was created by removing the polarizing film layer from the liquid crystal display screen of an iPad Air (Apple Inc, Cupertino, CA). Patients were asked to wear special glasses that contained a polarizing filter for their amblyopic eye and a light reduction filter for their no...

Amblyopia is a neuronal abnormality of vision that is often considered irreversible in adults. We found strong and significant improvement of Vernier acuity in human adults with naturally occurring amblyopia following practice. Learning was strongest at the trained orientation and did not transfer to an untrained task (detection), but it did transfer partially to the untrained eye (primarily at...

Amblyopia, or commonly referred as lazy eye, can be defined as a reduction in vision with no demonstrable abnormality of the visual pathway that is not immediately resolved by refractive correction.1 With a prevalence of 3-5%, amblyopia represents a major public health problem. In fact, amblyopia is the leading cause of monocular vision loss in the United States in people younger than 40 years....

purpose : to evaluate the visual results of amblyopic therapy in pediatric patients with monocular abnormalities. methods : the hospital records of visually immature patients with unilateral organic ocular abnormalities and decreased visual acuity, who presented to the pediatric ophthalmology clinic over a one year period, were reviewed. those who had 8 years old of age or less and underwent am...

purpose: to compare amblyopia treatment knowledge employed by pediatric ophthalmologists and optometrist with general ophthalmologists and other ophthalmic fellowships in 2012. methods: this cross-sectional study was performed during the iranian society of ophthalmology annual meeting in 2012 through a questionnaire containing demographic information and 20 closed-answer questions based on ats’...

On the basis of the contrast sensitivity loss in amblyopia which mainly affects higher spatial frequencies, one would expect amblyopes to perceive sharp edges as blurred. We show that they perceive sharp edges as sharp and have veridical edge blur perception. Contrary to the currently accepted view, this suggests that the amblyopic visual system is not characterized by a blurred visual represen...

Objectives: Amblyopia is most common binocular vision anomalies. To comprise is decrease of visual acuity witch doesnchr('39')t remove by optical correction. Nowadays because of the psychosocial problem with amblyopia, is a functional disability. Awareness of parents of children with amblyopic life experience, when facing with curing system can provide effective for promotion of self-assessment...

Using a task which relied upon the detection of sinusoidal deformations from circularity, we show that strabismic amblyopes exhibit deficits which are not critically dependent on either the scale of deformation or the spatial frequency characteristics of the stimulus (circular D4) itself. We show that this loss is not due to the restricted passband of the amblyopic eye. Furthermore, in a pedest...

For over a hundred years, patching of the good eye has been the main and often only method of treating a 'lazy' or amblyopic eye. A recent study shows that a period of time in complete darkness can promote rapid recovery of vision.
