Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases.  Furtherm...

OBJECTIVE To determine the effectiveness of screening for visual impairment in people aged 75 or over as part of a multidimensional screening programme. DESIGN Cluster randomised trial. SETTING General practices in the United Kingdom participating in the MRC trial of assessment and management of older people in the community. PARTICIPANTS 4340 people aged 75 years or over randomly sampled...

Methods to assess the visual quality of digital videos as perceived by human observers are becoming important, due to large number of applications that target humans as the end users of video. In this paper a no-reference video quality assessment (VQA) algorithm is introduced. Characteristics of human visual system (HVS) is taken into considerations. The quality of video is calculated in compre...

AIM To evaluate the correlation between visual function and neurodevelopmental outcome in children with periventricular leucomalacia at 1 and 3 years. METHOD Visual acuity, visual field, ocular motility, and optokinetic nystagmus were tested in 29 infants with periventricular leucomalacia by brain magnetic resonance imaging. All infants also had a structured neurological examination and a Gri...

Background and Aim: Objective measurement of visual acuity using VEP is high valued in patients with low levels cooperation. Therefore, this study aimed to investigate the effect spatial frequency on components Sweep VEP.

A number of recent studies investigated the use of morphological characteristics of the distal humerus to estimate the sex of unknown individuals. Using visual assessment, accuracies ranging from 74% to more than 90% were reported. The aim of this study was to assess these traits with geometric morphometrics, in order to determine if they corroborate the findings described with pure visual asse...

We have developed an electronic spatial frequency sweep technique for electrophysiological assessment of visual acuity and pattern vision. The technique allows an accurate and reliable measurement of VEPs to a full range of spatial frequencies in just 10 sec. Because the measurements are so rapid, the technique suggests several new improvements in the assessment of visual function. Sweeping spa...

The World Health Organization has endorsed the use of outreach to promote: efficient redeployment of the health-care workforce; continuity of care at the local level; and professional support for local, rural, health-care workers. Australia is the only country that has had, since 2000, a sustained national policy on outreach for subsidizing medical specialist outreach to rural areas. This paper...
