Driving under low-contrast visibility conditions in Parkinson disease.

4 Oct 2009 OBJECTIVE: To assess driving performance in Parkinson disease (PD) under low-contrast visibility conditions. METHODS: Licensed, active drivers with mild to moderate PD (n = 67, aged 66.2 +/- 9.0 years, median Hoehn-Yahr stage = 2) and controls (n = ... Read more...

Implantation of the multifocal ReSTOR apodised diffractive intraocular lens in adult anisometropic patients with mild to moderate amblyopia.

29 Sep 2009 AIM: To assess subjective and objective parameters of visual function after implantation of the AcrySof ReSTOR in amblyopic patients. METHODS: Phacoemulsification and IOL implantation were performed in six eyes of three patients with anisometropic ... Read more...

The role of background statistics in face adaptation.

28 Sep 2009 Cross-adaptation is widely used to probe whether different stimuli share common neural mechanisms. For example, that adaptation to second-order stimuli usually produces little aftereffect on first-order stimuli has been interpreted as reflecting ... Read more...

Technical information about 'Contrast Sensitivity'

Definition: The ability to detect sharp boundaries (stimuli) and to detect slight changes in luminance at regions without distinct contours. Psychophysical measurements of this visual function are used to evaluate visual acuity and to detect eye disease.
