Title: Crowded Letter and Crowded Picture LogMAR acuity in Children with Amblyopia: a quantitative comparison. Sub-Title: Comparing crowded letter and picture acuity in children with amblyopia. Authors:
Aims: Clinically, picture acuity tests are thought to overestimate visual acuity (VA) compared with letter tests, but this has not been systematically investigated in children with amblyopia. This study compared VA measurements with the LogMAR Crowded Kay Picture test to the LogMAR Crowded Keeler Letter acuity test in a group of young children with amblyopia. Methods: 58 children (34 male) with...

متن کاملTraining on spatiotemporal masking improves crowded and uncrowded visual acuity.
Spatial crowding impairs conscious visual perception and object recognition in clutter.Short presentation times produce crowding in the normal fovea, in young participants and in uncorrected presbyopes ("aging eye"), measured as reduced visual acuity (VA). On the other hand, perceptual learning improves near VA in healthy young adults, in presbyopia, and in amblyopia. Here we aimed at exploring...
متن کاملFactors affecting long term results of successfully treated amblyopia: initial visual acuity and type of amblyopia.
AIMS The study aimed to assess the effect of initial visual acuity and type of amblyopia on the long term results of successfully treated amblyopia. METHODS The visual acuity of 94 patients, who had been successfully treated for unilateral amblyopia by occlusion of the good eye and followed up to the age of 9 years, was examined 6.4 years, on average, after cessation of treatment. Patients we...
متن کاملSimulating retinal encoding: factors influencing Vernier acuity
Humans resolve the spatial alignment between two visual stimuli at a resolution that is substantially finer than the spacing between the foveal cones. In this paper, we analyze the factors that limit the information at the cone photoreceptors that is available to make these acuity judgments (Vernier acuity). We use open-source software, ISETBIO to quantify the stimulus and encoding stages in th...
