[Electronically recorded occlusion treatment in amblyopes older than 7 years: acuity gain after more than 4 months of treatment?].

Background: According to the ROTAS study most of the improvement in visual acuity (VA) during amblyopia therapy of children aged 3 to 8 years occurs during the first 6 to 8 weeks . Sattler reported a VA gain in 11-year olds even during the second year of treatment . So far there are no standards concerning the intensity and duration of the treatment of patients older than 7 years of age.

Electronic monitoring of occlusion treatment for amblyopia in patients aged 7 to 16 years.

Background: Age limits for the prescription of amblyopia treatment have been debated and challenged recently, due to results of studies from ophthalmology and the neurosciences. Lack of knowledge about compliance with prescribed treatment is still a major factor for the uncertainty about the amount of plasticity in the visual system of older children and adolescents. The development of devices for the electronic recording of patching (Occlusion Dose Monitor, ODM) has allowed the collection of objective data about daily occlusion.

[Spontaneous improvement of visual acuity in adult amblyopia after functional loss in the non-amblyopic eye?].

Background: The prognosis of functional improvement after vision loss in the non-amblyopic eye in adulthood is important for counselling of the patients, but uncertain for a number of reasons. Our study focuses on two aspects. Firstly, a questionnaire was developed asking ophthalmologists and orthoptists for their opinion about the chances of significant spontaneous improvement; secondly, patient data were analysed with respect to acuity data acquisition and documentation as reasons for uncertainty concerning the prognosis.

Children with developmental dyslexia show a left visual "minineglect".

We investigated the performance of children with developmental dyslexia on a visual line bisection task. Dyslexic children did not show the overestimation of the left visual field (pseudoneglect) characteristic of normal adult vision. These results suggest that children with developmental dyslexia present selective deficits in visual attention, probably involving neural structures located in the right posterior parietal cortex.

Saliency and context play a role in infants' texture segmentation.

We investigated whether young infants orient reliably towards more salient vs. less salient objects in a visual scene. Subjects were tested with stimuli presented on textured fields, one side showing a target stimulus (a 'more salient' or 'less salient' texture patch) and the other a background stimulus.
