Neuroplasticity and amblyopia: vision at the balance point.
PURPOSE OF REVIEW New insights into triggers and brakes of plasticity in the visual system are being translated into new treatment approaches which may improve outcomes not only in children, but also in adults. RECENT FINDINGS Visual experience-driven plasticity is greatest in early childhood, triggered by maturation of inhibitory interneurons which facilitate strengthening of synchronous syn...
متن کاملAmblyopia and binocular vision.
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...
متن کاملFoveal vision in amblyopia.
THE reduced visual acuity in amblyopic eyes has presented a.problem ever since the condition was recognized. Most of the evidence so far favours the cortex as the site of inhibition (Vogt, 1939; Wald and Burian, 1944; Dyer and Bierman, 1952). Clarke (1941) thought that the cause might be an atrophy from disuse affecting the cells of the lateral geniculate body which rely for their vitality on t...
متن کاملThreshold vision in amblyopia: orientation and phase.
PURPOSE The visual deficit in amblyopia involves both elevated contrast thresholds and distorted suprathreshold percepts at high spatial frequencies. It is currently unclear whether these two anomalies are part of the same neural disturbance or whether they reflect different neural dysfunction. METHODS The quality of the spatial percepts in amblyopia was assessed at detection threshold. The a...
متن کاملTowards Worldwide Amblyopia Elimination – Vision Screening
Amblyopia can be defined as the deficient development of brain vision during the first decade of human life, and is the topic of some excellent recent reviews.1–3 It remains a common cause of vision impairment in developed countries despite the fact that it is completely preventable and treatable. In some small-scale regional efforts in developed countries, deliberate screening combined with co...
