LASIK in children with hyperopic anisometropic amblyopia.
PURPOSE To evaluate the results of LASIK for hyperopia in pediatric eyes with amblyopia resulting from anisometropia. METHODS Thirty-two children with anisometropic amblyopia in whom conventional therapy was unsuccessful underwent unilateral LASIK between 1999 and 2005. Mean patient age was 10.3 +/- 3.1 years (range: 4 to 15 years), and mean follow-up was 20.1 +/- 15.1 months (range: 12 to 60...
متن کاملPhotorefractive keratectomy for anisometropic amblyopia in children.
PURPOSE To assess the safety and efficacy of photorefractive keratectomy (PRK) in children with anisometropic amblyopia and to define the characteristics of children who may be candidates for PRK. METHODS This thesis comprises four parts: (1) a retrospective analysis of risk factors predictive of amblyopia treatment failure in 104 children, (2) a prospective study of pachymetry in 198 eyes of...
متن کاملAdvanced 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 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...
