For five anisometropic amblyopes and five normal controls, contrast sensitivities in both grating motion direction discrimination and moving grating detection were measured with the same moving sine-wave stimuli over a wide range of spatial and temporal frequencies. We found that the apparent local motion deficits in anisometropic amblyopia can be almost completely accounted for by deficits in ...

AIMS To assess calcarine activation with functional magnetic resonance imaging (fMRI) in patients with anisometropic and strabismic amblyopia. METHODS 14 amblyopes (eight anisometropic and six strabismic) were studied with fMRI using stimuli of checkerboards of various checker sizes and temporal frequencies. While T2* weighted MRI were obtained every 3 seconds for 6 minutes, patients viewed t...

PURPOSE This study was designed to assess and compare the thicknesses of the fovea and the retinal nerve fiber layer in normal children and children with amblyopia. METHODS Optical Coherence Tomography (OCT) was performed on 26 children (52 eyes total) with unilateral amblyopia that was due to anisometropia or strabismus. OCT was also performed on 42 normal children (84 eyes), for a total of ...

Background/Objective: Amblyopia also known as lazy eye is an abnormal condition which associated with decrease in vision. Parents can play important role the management of amblyopia their children, if they have correct information regarding disease. The present study was conducted to check parents awareness and perception treatment, diagnosis, causes consequences Al-Jouf region Saudi Arabia. Me...

Introduction Amblyopia is the leading cause of reduced vision in children following cataract surgery. It may develop as a consequence of visual deprivation, anisometropia, or strabismus. Methods: Animal studies as well as clinical series were reviewed focusing on the pathophysiology and treatment of aphakic and pseudophakic amblyopia. Results: Excellent visual outcomes have been reported in chi...

Traditional treatment of amblyopia, although still in use and of great value, has recently been challenged by data from studies relative to efficacy of different modalities and regimens of therapy. LogMAR-based acuity charts should be used, whenever possible, for diagnosis and monitoring. Refractive errors of certain magnitude should be prescribed, and correction worn for at least 4 months befo...

Amblyopia, a developmental disorder of the visual cortex, is one of the leading causes of visual dysfunction in the working age population. Current estimates put the prevalence of amblyopia at approximately 1-3%(1-3), the majority of cases being monocular(2). Amblyopia is most frequently caused by ocular misalignment (strabismus), blur induced by unequal refractive error (anisometropia), and in...
