    Area of Science:

    • Ophthalmology
    • Rehabilitation Medicine
    • Assistive Technology

    Background:

    • Veterans often experience vision loss due to various pathologies.
    • Access to assistive technology is crucial for maintaining independence.
    • Closed-circuit televisions (C.C.T.V.) are a potential tool for visual impairment rehabilitation.

    Purpose of the Study:

    • To evaluate the use and usefulness of C.C.T.V. for visually impaired veterans.
    • To assess the impact of C.C.T.V. on daily functioning.
    • To determine the long-term benefits of C.C.T.V. adoption.

    Main Methods:

    • A preliminary follow-up study involving 27 veterans.
    • Participants were loaned C.C.T.V. devices by the Veterans Administration.
    • Data collected from a diverse group of veterans with varying ages, backgrounds, and visual pathologies.
