Digital Accessibility in Iran: An Investigation Focusing on Iran\u27s National Policies on Accessibility and Disability Support
Digital accessibility has become an important topic in the field of HCI, but when looking at accessibility on a global scale, we find that the representation of accessibility research is mostly centered in the Global North with countries that are WEIRD (Western, Educated, Industrialized, Rich, and Democratic). Our paper explores digital accessibility in Iran, focusing exclusively on its national policies on accessibility. Iran is a non-WEIRD country located in the Global South, with no reports on its digital accessibility status from the Global Initiative for Inclusive Information and Communication Technologies (G3ict). We found that there is not enough focus on accessibility in Iran\u27s regulations and we conclude our paper by recommending directions for improving this situation such as HCI and disability organizations in Iran cooperating with G3ict
Contrast Sensitivity versus Visual Evoked Potentials in Multiple Sclerosis
Purpose: To compare the Cambridge contrast sensitivity (CS) test and visual evoked potentials (VEP) in detecting visual impairment in a population of visually symptomatic and asymptomatic patients affected by clinically definite multiple sclerosis (MS).
Methods: Fifty patients (100 eyes) presenting with MS and 25 healthy subjects (50 eyes) with normal corrected visual acuity were included in this study. CS was determined using the Cambridge Low Contrast Grating test and VEP was obtained in all eyes. Findings were evaluated in two age strata of 10-29 and 30-49 years.
Results: Of the 42 eyes in the 10-29 year age group, CS was abnormal in 22 (52%), VEP was also abnormal in 22 (52%), but only 12 eyes (28%) had visual symptoms. Of the 58 eyes in the 30-49 year group, CS was abnormal in 7 (12%), VEP was abnormal in 34 (58%), while only 11 eyes were symptomatic. No single test could detect all of the abnormal eyes.
Conclusion: The Cambridge Low Contrast Grating test is useful for detection of clinical and subclinical visual dysfunction especially in young patients with multiple sclerosis. Nevertheless, only a combination of CS and VEP tests can detect most cases of visual dysfunction associated with MS
