PURPOSE This study was conducted to investigate the role of the pattern visual evoked potential (pVEP) as a predictor of occlusion therapy for patients with strabismic, anisometropic, and isometropic amblyopia. The secondary aim was to compare the characteristics of pVEP between strabismic and anisometropic amblyopia. METHODS This retrospective comparative case series included 120 patients wh...

. to investigate the effect of anisometropic and strabismic amblyopia on the nerve fiber layer thickness. this cross-sectional study was done on 54 amblyopic subjects, equally in both strabismic and anisometropic groups. the thickness otonerve fiber layer measured in superior, inferior, nasal, temporal quadrants and as a whole in both eyes of both groups. the means of thickness were compared in...

Introduction: Strabismic amblyopia is frequently encountered by pediatric ophthalmologists and orthoptists. An understanding of its onset and of the timing of treatment may lead to better long-term treatment results. Methods: A review was conducted of past and recent literature pertaining to strabismic amblyopia. Articles relevant to further understanding the onset, course, and management of st...

Contour integration was measured in a group of anisometropic amblyopes to test the idea recently put forward that positional uncertainty sets a fundamental limit to contour integration in amblyopia. Anisometropic amblyopia, unlike strabismic amblyopia, has little or no positional uncertainty once the initial filtering loss has been taken into account. Therefore, according to the explanation put...

OBJECTIVE To report successful therapy for anisometropic and strabismic amblyopia initiated after age 7 years. METHODS A consecutive series of 36 compliant children older than 7 years (range, 7.0 to 10.3 years; mean, 8.2 years) at initiation of amblyopia therapy for anisometropic (19 patients; mean age, 8.3 years), strabismic (9 patients; mean age, 8.0 years), or anisometropic and strabismic ...

In order to evaluate the influence of etiology of amblyopia and of age at onset of amblyopia on the resulting constellation of spatial vision deficits, resolution/vernier and recognition/resolution acuity ratios were measured in groups of children with either strabismic amblyopia or anisometropic amblyopia with known ages of onset. Strabismic amblyopia with infantile onset (<9 months) and strab...

Foveal vision in strabismic amblyopia can show increased levels of crowding, akin to typical peripheral vision. Target-flanker similarity and visual-acuity test configuration may cause the magnitude of crowding to vary in strabismic amblyopia. We used custom-designed visual acuity tests to investigate crowding in observers with strabismic amblyopia. LogMAR was measured monocularly in both eyes ...

OBJECTIVE To find the causes of amblyopia in patients 4 to 14 years old attending out patient Ophthalmology department of Khyber teaching Hospital Peshawar. METHODS In this prospective cohort hospital based study 200 children aged 4-14 years were studied over a period of 12 months from December 2005 to November 2006 in outpatient department of Ophthalmology, Khyber Teaching Hospital. Visual a...

Human psychophysical studies suggest that strabismic and anisometropic amblyopes may have characteristically different patterns of visual loss. In particular, anisometropic amblyopes often show deficits on spatial localization tasks that scale with their spatial resolution losses, whereas strabismic amblyopes can show localization deficits that are large relative to their losses in spatial reso...
