If amblyopia is defined as reduced visual acuity in an eye which appears normal on examination, then it is necessary to distinguish between several related, similar, or different conditions that fit this definition. Six years ago I proposed a classification of amblyopia in which the various factors leading to its development were enumerated in the light of our clinical knowledge at that time (v...

Amblyopia is the most common cause of monocular visual impairment in both children, and young to middle-aged adults, affecting 2%–5% general population. The objective this study was compare peripapillary nerve fiber thickness macular amblyopic eyes, fellow eyes normal control using spectral domain optical coherence tomography. This a cross-sectional observational conducted at R M Kedia Eye Hosp...

OBJECTIVE To assess the effectiveness of early treatment for amblyopia in children. DESIGN Follow up of outcomes of treatment for amblyopia in a randomised controlled trial comparing intensive orthoptic screening at 8, 12, 18, 25, 31, and 37 months (intensive group) with orthoptic screening at 37 months only (control group). SETTING Avon, southwest England. PARTICIPANTS 3490 children who ...

BACKGROUND Aberrant regeneration of the third cranial nerve is most commonly due to its damage by trauma. CASE A ten-month old child presented with the history of a fall from a four-storey building. She developed traumatic third nerve palsy and eventually the clinical features of aberrant regeneration of the third cranial nerve. The adduction of the eye improved over time. She was advised for...

Amblyopia is a neurodevelopmental disorder of the visual system that is associated with disrupted binocular vision during early childhood. There is evidence that the effects of amblyopia extend beyond the primary visual cortex to regions of the dorsal and ventral extra-striate visual cortex involved in visual integration. Here, we review the current literature on global processing deficits in o...

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...

IN the refraction clinic the visual improvement cannot always be correlated with the degree of anisometropia. The literature shows that anisometropic amblyopia is a well-recognized condition, but opinions differ regarding the relationship between anisometropia and amblyopia. As the published studies do not consider the factor of eccentric fixation as a possible variable, we have investigated it...

BACKGROUND We compared the wave amplitude of visually evoked potential (VEP) between patients with esotropic and anisometropic amblyopic eyes and a normal group. METHODS The wave amplitude of VEP was documented in 2 groups of persons with amblyopia (15 with esotropia and 28 with anisometropia) and 1 group of individuals with normal visual acuity (n, 15). The amplitude of P100 was recorded mon...
