OBJECTIVE To determine the value of pattern visual evoked potential (PVEP) testing with 5 consecutive check-size patterns in presumably malingering draftees. DESIGN Case-control study. PARTICIPANTS The study group included 111 military conscripts (124 eyes) whose visual abnormalities could not be explained by the findings of ophthalmologic,(More)

METHODS Two-hundred-twenty-eight eyes of 212 consecutive patients, who were mostly injured in military confrontation,(More)
PURPOSE To evaluate the location and shift of the pupil center relative to the coaxially sighted corneal reflex on horizontal and vertical planes under natural and pharmacologically dilated conditions. METHODS Ninety-four (64 myopic and 30 hyperopic) eyes of 47 patients underwent pupillometry with the NIDEK OPD-Scan under photopic and mesopic conditions(More)
PURPOSE To assess the structural and functional status of patients with multiple sclerosis (MS) without a history of optic neuritis.

The aim of this study was to investigate the intra-sessional and inter-sessional variability of the multifocal electroretinogram (mfERG). Right eyes of 20 healthy adult subjects with uncorrected visual acuity of 1.0 were studied. mfERG recordings were obtained in two sessions by using jet corneal electrodes. The responses were averaged over five retinal(More)
