Reading Performance With a Video Magnifier
The most common goal for patients with vision loss who present for vision rehabilitation is to be able to read. The video magnifier (a device which combines a video camera and a screen to view the print being magnified) is the device which most often allows low-vision individuals to read successfully for extended periods of time. Previous studies on the outcomes of vision rehabilitation have not identified which components of the vision rehabilitation are effective. The hypothesis of this project is that providing a video camera magnifier, with basic training in operating the device, will allow patients to enhance both objective reading ability and subjective report of reading competence.
|Study Design:||Observational Model: Case-Crossover
Time Perspective: Prospective
|Official Title:||The Effect of Video Camera Magnifier Use on Reading|
- Change in objective reading performance [ Time Frame: baseline and one month ] [ Designated as safety issue: No ]The subject undergoes testing to determine the change in reading performance on an objective scale.
- Change in subjective reading performance [ Time Frame: baseline and one month ] [ Designated as safety issue: No ]The subject is asked to describe subjectively how they feel their ability to read has either improved or decreased since using the reader.
