evaluation of contrast sensitivity, color vision and visual acuity in patients with and without diabetes
purpose : to investigate the discriminative ability of contrast sensitivity (cs), color vision and best corrected visual acuity (bcva) in detecting functional losses in diabetic participants with and without retinopathy methods : in this cross sectional study we examined 105 patients in khatam-al-anbia eye hospital of mashhad university of medical sciences including 70 diabetic patients (35 wit...
متن کاملSimilar contrast sensitivity functions measured using psychophysics and optokinetic nystagmus
Although the contrast sensitivity function (CSF) is a particularly useful way of characterising functional vision, its measurement relies on observers making reliable perceptual reports. Such procedures can be challenging when testing children. Here we describe a system for measuring the CSF using an automated analysis of optokinetic nystagmus (OKN); an involuntary oscillatory eye movement made...
متن کاملEfficacy of neural vision therapy to enhance contrast sensitivity function and visual acuity in low myopia.
PURPOSE To evaluate the efficacy and safety of neural vision enhancement technology (NVC, NeuroVision, Inc.) to improve visual acuity and contrast sensitivity function in eyes with low myopia. SETTING Singapore Eye Research Institute, Singapore, Singapore. METHODS This noncomparative interventional case series comprised 20 Asian adults between 19 and 53 years of age with low myopia (cyclopl...
متن کاملQuick contrast sensitivity measurements in the periphery.
Measuring the contrast sensitivity function (CSF) in the periphery of the eye is complicated. The lengthy measurement time precludes all but the most determined subjects. The aim of this study was to implement and evaluate a faster routine based on the quick CSF method (qCSF) but adapted to work in the periphery. Additionally, normative data is presented on neurally limited peripheral CSFs. A p...
متن کاملContrast sensitivity in multiple sclerosis measured by Cambridge Low Contrast Gratings: a useful clinical test?
The Cambridge Low Contrast Gratings (CLCG) were used to assess contrast sensitivity (CS) in 39 patients with clinically definite multiple sclerosis and 60 control subjects. CS was determined in both horizontal and vertical orientations and compared with visual evoked responses (VERs) in the same populations. Only 33% of patients had abnormal CS whereas 82% had abnormal VERs. There was no correl...
