Advanced Analysis of PRVEP in Anisometropic Amblyopia
Introduction: to identify the pattern-reversal visual evoked potential (PRVEP) waveform descriptor by evaluating discrete wavelet transform (DWT) in order to optimize stimulus in the diagnosis of anisometropia amblyopia. Materials and Methods: The PRVEP testing was performedfor 31 normal individuals and 35 patients with amblyopia. The stimuli were consisted of spatial frequencies of 1, 2, and 4...
متن کاملA Study of Amblyopia among Anisometropic Patients
DOS Times Vol. 11, No. 10 April, 2006 Amblyopia is defined as unilateral or bilateral decrease of visual acuity caused by vision deprivation or abnormal binocular interaction for which no organic causes can be detected by the physical examination of the eye and which in appropriate cases is reversible by therapeutic measures1,2,3. For detection purposes, on routine examination, amblyopia is def...
متن کاملAnisometropic Amblyopia: Nonsurgical Treatment
Anisometropic amblyopia is characterized by a decrease in best corrected visual acuity in one eye as a result of significantly different refractive errors between the two eyes. The eye that ultimately provides a more blurred image to the visual cortex develops amblyopia.1 Several authors have suggested that anisometropia is the leading cause of amblyopia and is responsible for approximately 50%...
متن کاملContour integration in anisometropic amblyopia
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...
متن کاملContrast sensitivity in anisometropic amblyopia.
Contrast sensitivity functions were measured for sinusoidal gratings from a sample of 10 anisometropic amblyopes. A high spatial frequency deficit was found from tests of the amblyopic eyes of all subjects. This defect decreased with spatial frequency and was correlated with the magnitude of anisometropia. Controls were instituted to rule out psychophysical method and residual defocus as possib...
