Computerized method of visual acuity testing: adaptation of the amblyopia treatment study visual acuity testing protocol.
PURPOSE To report a computerized method for determining visual acuity in children using the Amblyopia Treatment Study visual acuity testing protocol. METHODS A computerized visual acuity tester was developed that uses a programmed handheld device that uses the Palm operating system (Palm, Inc, Santa Clara, California). The handheld device communicates with a personal computer running a Linux ...
متن کاملVisual acuity testing in young children.
Various tests are in common use for determining the visual acuity (VA) in children, and this paper reports the results of an investigation into some of them in regard to their accuracy, acceptability, and comparability. Early assessment of the VA is desirable in order to detect any abnormality, but through lack of co-operation and comprehension, it cannot usually be carried out until the age of...
متن کاملAnomaly in visual acuity testing in children.
A popular and widely used method of visual acuity testing of young children is criticized on the grounds that it often fails to elicit amblyopia. The results obtained when the visual acuity of thirty amblyopic children was tested by different methods show that monotype testing gives an apparent acuity averaging three grades better than those derived from the standard Snellen's test.
متن کامل2C Vision Game: Visual Acuity Self-Testing Using Mobile Devices
This paper explores non-intrusive, engaging, and cost effective mobile health methods to detect and monitor changes in visual acuity caused by diabetic retinopathy (linked to diabetes) and macular degeneration (linked to aging). These prevalent conditions can both lead to blindness if undetected early in their gradual progression. By leveraging mobile computing platforms and sensor technology, ...
متن کاملVisual acuity testing. From the laboratory to the clinic
The need for precision in visual acuity assessment for low vision research led to the design of the Bailey-Lovie letter chart. This paper describes the decisions behind the design principles used and how the logarithmic progression of sizes led to the development of the logMAR designation of visual acuity and the improved sensitivity gained from letter-by-letter scoring. While the principles ha...
