INTRODUCTION AND PURPOSE The treatment of amblyopia in children is frequently discussed in the literature. Less attention, however, has been given to the durability of the visual acuity results attained with therapy. The objective of this review is to conduct an in-depth analysis of the existing literature, on the stability of visual acuity following cessation of amblyopia treatment, and to ide...

Amblyopia can be produced in rhesus monkeys by suturing the lids of one eye (visual deprivation amblyopia) or by producing artificial esotropia (strabismic amblyopia) during visual immaturity. Sections from retinas, lateral geniculate nuclei (LGN), and areas 17 and 18 of the visual cortex from monkeys with behaviorally proved amblyopia and cortical neurophysiologic changes were examined histolo...

Both visual acuity (VA) and contrast sensitivity (CS) are important parameters for measuring visual function. In this research, we investigated the CS of patients with ametropic or anisometropic amblyopia, whose corrected visual acuity (CVA) recovered to 1.0. Fifty-five cases with amblyopia and 22 control cases with a normal visual acuity of 1.0 were enrolled. The CS of the patients whose ametr...

BACKGROUND The purpose of this study was to compare a weight-adjusted dose of carbidopa- levodopa as treatment adjunctive to occlusion therapy with occlusion therapy alone in children and adults with different types of amblyopia. METHODS This prospective study included 63 patients with amblyopia classified into two groups, ie, an occlusion group which included 35 patients who received occlusi...

Amblyopia, a decrease in visual acuity, is a major public health problem with a prevalence of 1 to 4 percent in the United States. It is thought to develop early in life during the critical period of visual development. Early recognition of amblyogenic risk factors such as strabismus, refractive errors, and anatomic obstructions can facilitate early treatment and increase the chance for recover...

Amblyopia, or ‘lazy eye’, is currently treated by wearing an adhesive patch over the nonamblyopic eye for several hours per day, over a period of many months. Non-compliance with patch wearing is a significant problem. Our multi-displinary team involved clinicians and technologists to investigate the application of VR technology in a novel way. We devised a binocular treatment system in which c...

We show that the previously reported orientation deficit in amblyopia (Skottun, B. C., Bradley, A., & Freeman, R. D. (1986). Orientation discrimination in amblyopia. Investigative Ophthalmology and Visual Science, 30, 532-537) also occurs for arrays of randomly positioned Gabor micropatterns for which explanations based on either neural disarray or local neural interactions would not hold. Furt...

Over the last 50 years, research into the developmental plasticity of the visual cortex has led to a growing understanding of first the causes and then of the underlying cellular mechanisms of amblyopia or 'lazy eye', the commonest childhood disorder of vision. While it is widely believed that amblyopia cannot be treated successfully after the age of about 7, recent animal studies have demonstr...

Refractive errors are a common cause of decreased visual acuity. They can be found in 2-4% of preschool children. If not discovered on time and not properly treated, they can lead to amblyopia and strabismus. The active participation of parents and paediatricians is of great importance in timely discovering and treatment of amblyopia. The most common causes of amblyopia are strabismus (50.1%) a...

We assessed 18 children with unilateral amblyopia and 30 age-matched controls on one low-level and three high-level motion tasks. Children with amblyopia showed similar performance to controls in both amblyopic and fellow eyes on a low-level global motion task and on a high-level 2-dot apparent motion task. Performance on both single-object and multiple-object attentive tracking tasks was signi...
