PURPOSE To test the hypothesis that eyes with amblyopia may have thicker retina, retinal nerve fiber layer thickness (RNFLT) was investigated in patients with unilateral amblyopia. METHODS Thirty-eight patients with unilateral amblyopia were studied. Among them, 20 patients had amblyopia with strabismus and 18 had refractive amblyopia without strabismus. Nineteen of 38 had anisometropia of 2....

Amblyopia is the most common cause of monocular visual loss in children, affecting 1.3%-3.6% of children. Current treatments are effective in reducing the visual acuity deficit but many amblyopic individuals are left with residual visual acuity deficits, ocular motor abnormalities, deficient fine motor skills, and risk for recurrent amblyopia. Using a combination of psychophysical, electrophysi...

Comment. In this population-based cohort of children diagnosed as having periocular infantile hemangioma during a 40-year period, amblyopia with or without strabismus occurred in approximately 1 in 5 children. To our knowledge, this study is the first population-based report on periocular infantile hemangiomas in the United States. The rate of amblyopia of 19% in this population is significantl...

Amblyopia is a neuro-developmental disorder of the visual cortex that arises from abnormal visual experience early in life. Amblyopia is clinically important because it is a major cause of vision loss in infants and young children. Amblyopia is also of basic interest because it reflects the neural impairment that occurs when normal visual development is disrupted. Amblyopia provides an ideal mo...

Editorials Anisometropia and amblyopia-chicken or egg? Amblyopia continues to attract tremendous interest from basic scientists and clinicians, yet surprisingly large gaps in our understanding of this topic remain. One of these is highlighted by Abrahamsson and Sj6strand who describe in this issue of the B7O (p 860) a meticulous follow up of 20 children to the age of 10 who at 1 year of age had...
