VEP estimation of visual acuity: a systematic review

Psychometric Properties of Tools Used for Children and Adolescents With Visual Impairments: A systematic Review Study

Objectives: The use of standard tools can show the exact effects of interventions in children and adolescents with visual impairment (CYP-VI). However, to date, no comprehensive review study has evaluated the general characteristics and psychometrics of the instruments used in CYP-VI. Therefore, the present study investigated the psychometric properties of the tools used for CYP-VI.  Methods: ...

Detection of Amblyopia Using Sweep VEP Vernier and Grating Acuity

Purpose Vernier and grating acuity can be measured with swept-parameter visual evoked potentials (sVEP). However, whether sVEP Vernier and grating acuities are comparable in predicting letter acuity has not been systematically evaluated. This study evaluated the validity and reliability of sVEP Vernier and grating acuity for the detection of amblyopia in adults. Methods Three types of acuity ...

A Systematic Review for Estimation of HTLV-I Infection in the Blood Donors of Iran

Objective estimation of visual acuity with preferential looking.

PURPOSE A novel preferential looking (PL) procedure that uses quantitative analysis of visual scanning parameters is presented. METHODS Nine adult subjects were presented with a set of 14 visual stimuli (stimuli included three uniform gray fields and one field with black-and-white square wave gratings) spanning the range of spatial frequencies from 1.5 cyc/deg to 35.1 cyc/deg (1.3 logMAR to -...

Visual evoked potentials (VEP) and visual acuity improvement after cytidine 52 - diphosphocholine (CDP-Choline) therapy in amblyopic patient

Citicoline may be used in many neurological disorders. Combined treatment of citicoline with patching in amblyopia has previously been researched. The purpose of this paper is to illustrate the effect of citicoline in non-patching amblyopic patient. A 11-year-old amblyopic boy underwent complete ophthalmological examinations, including VEP with flash and pattern stimulus. Two averages of 100 sw...
