“…This result is coincident with the outcomes reported by Rice M. et al 43 who also found an MD of 0.06 logMAR between ATS and ETDRS. Leone J et al 44 also found a better VA with the ATS procedure than with HOTV and ETDRS charts even though the latter ones incorporated a staircase method that improves the VA results.…”

Visual acuity and contrast sensitivity with iPad 2 2. Structured abstract. PurposeTo present two iPad applications (apps) for measuring Visual Acuity (VA) and Contrast Sensitivity Function (CSF) and to assess reliability and agreement with a commercial screening device. MethodsForty-five healthy subjects with monocular corrected visual acuities better than 0.2 logMAR participated in the agreement study of VA and CSF with iPad and Optec 6500. Results MD of VA was 0.06 logMAR better with AmblyopiaVA than with ETDRS (p<0.001) andLoAs were around ±0.2 logMAR. Test-retest reliability was better with AmblyopiaVA (r=0.15) with no statistically significant differences between days (p>0.05). A good agreement with no significant differences (p>0.05) was obtained with ClinicCSF and FACT. MDs were below 0.05 log units at all the spatial frequencies but non-constant LoAs were manifested at 3.6 and 18 cpd. Null hypotheses of same medians along days were accepted for both tests (p>0.05) but reliabilities were poorer with the increment of the spatial frequency. ConclusionsThe iPad tests showed a good agreement with conventional tests and may be a convenient and faster alternative to some existing commercial screening devices. On the other hand future improvements in test-retest reliabilities should be done for the screening of CSF.

“…Visual acuity testing using HOTV for children 5-12 years of age has been used in place of the ETDRS chart in some studies in an attempt to improve testability in younger children. 2 However, ETDRS continues to be used in recent studies of 5-to 12-year-olds. 4,5 Use of pictures for visual acuity testing in young children, as in the Lea charts, has been used with high testability but has been shown to overestimate visual acuity in some children with visual impairment.…”

Vision assessment using the NIH Toolbox

Vision is a sensation that is created from complex processes and provides us with a representation of the world around us. There are many important aspects of vision, but visual acuity was judged to be the most appropriate vision assessment for the NIH Toolbox for Assessment of Neurological and Behavioral Function, both because of its central role in visual health and because acuity testing is common and relatively inexpensive to implement broadly. The impact of visual impairments on health-related quality of life also was viewed as important to assess, in order to gain a broad view of one's visual function. To test visual acuity, an easy-to-use software program was developed, based on the protocol used by the E-ETDRS. Children younger than 7 years were administered a version with only the letters H, O, T, and V. Reliability and validity of the Toolbox visual acuity test were very good. A 53-item vision-targeted, health-related quality of life survey was also developed. Neurology Vision is a complex sensation that provides us with a personal representation of our surrounding environment. The process resulting in vision begins when the cornea and lens refract light from objects and surfaces in the world to form a panoramic, hemispheric image on the retina, the thin layer of nerve cells that lines the inside surface of the eye. Like pixels in a digital camera, photoreceptor cells sample the light in the retinal image and photochemically transform the absorbed light energy into neural signals that are processed first by neurons in the retina and then by neurons in the visual parts of the brain.The important aspects of visual sensation that may vary in the general population or that can be impaired by diseases or disorders of the visual system include resolution of detail, field of view, appearance of contrast, appearance of colors, appearance of motion, resolution of depth, seeing in dim light, and seeing in glaringly bright light.Vision was identified as the highest-ranking sensory subdomain for inclusion in the NIH Toolbox for Assessment of Neurological and Behavioral Function (NIH Toolbox) on an online request for information from the expert research community (primarily NIH-funded investigators actively involved in neurologic or behavioral research; n 5 232). Reasons that experts ranked vision highly included its impact on independence, function, safety, and well-being for individuals of all ages, and the fact that vision may affect the quality of other senses. Two aspects of vision that were prioritized for testing in the NIH Toolbox vision subdomain were visual acuity and the impact of visual function on health-related quality of life. The selection criteria emphasized tests that would be reliable, valid, cost-and time-efficient, portable, and appropriate for a broad age range (3-85 years), and would not overly burden the test participants. Visual acuity was selected for testing in the NIH Toolbox because loss of visual acuity is the most common and important form of visual impairment that may reduce ...

“…The only stimulus variable is represented by the size of the test items graduated in 0.1 log unit steps, equivalent to the logarithmical scaling given by the EN ISO 8596 [4,22,27]. The separation within and between the lines is uniform, providing constant geometric proportions for all testing distances, so that contour interaction is controlled [24].…”

“…1 The Radner Reading Charts for the simultaneous determination of reading acuity and reading speed commonly used in ophthalmological studies for measuring visual acuity in adults [8,9]. In children, the ETDRS charts are considered to be the test of choice, when the children are able to cope with the testing procedure [11,20,27]. All these design characteristics have been applied for developing the sentence optotypes of the German Radner Reading Charts (RR Charts; Fig.…”

“…The test items have to be of approximately equal legibility and the separation of the optotypes should be uniform [4,22]. For evaluating visual function in children with microstrabismus, vision tests have also to consider the characteristics of amblyopic vision [13,27,29]. For accurate and standardized measurements at every viewing distance, the print sizes of the optotypes should be logarithmically scaled, and the test items should be as comparable as possible, both representing main characteristics of the Landolt C test defined in the European international standard EN ISO 8596 [1,[24][25][26].…”
