Divergent contrast sensitivity findings have been reported in patients with intraocular lens implants. In this study, contrast sensitivity to stationary sine-wave gratings of six spatial frequencies from 0.5 to 22.8 cycles/degree was measured psychophysically in 13 patients with posterior chamber intraocular lens implants and in 10 controls.

A patient with Aicardi syndrome is presented. We report results of DNA analysis from the patient and her parents with probes mapped to Xp21.3-22.3 in an attempt to localize a deletion in this region. No signs of a microdeletion could be detected, using 5 different DNA markers. Further, it is suggested that a specific combination of cerebral abnormalities(More)
Seventy-one children, age 4-12 years, with subnormal visual acuity (VA) in at least one eye (0.7 or less) were examined using visual evoked cortical potentials (VECPs) to pattern-reversal stimulation. Twenty-eight children with squint had mean VA 0.3 in squinting and 0.7 in non-squinting eyes. Thirty-one children had unexplained subnormal VA, mean 0.6.(More)
Visual evoked cortical potentials (VECP) were recorded from 10 subjects with normal visual acuity (VA) 1.0. Reversing square-wave gratings of 16 different spatial frequencies were used as stimuli. In all 10 subjects significant increase in power at the stimulation frequency was observed in the Fourier spectrum. The VA, calculated from the Fourier spectra,(More)
