    JOSA A FEATURE ANNOUNCEMENT
    Aging of the Human Visual System
    Submission Deadline: February 1, 2001

    The editors of JOSA A are soliciting papers for a special issue on aging of
    the visual system and vision. The study of lifespan changes in human vision
    and physiological optics is a topic of continuing interest of members of
    the Optical Society of America. The population as a whole is aging; it
    therefore becomes crucial to study how vision changes and how to maximize
    useful vision for as long as possible.
    A complete understanding of vision includes the mechanisms at work for
    people of all ages, and how these change. An accurate view is not limited
    to a snapshot of young adults. In the human visual system, both structure
    and function continue to change from birth onward. A broad scientific
    approach, encompassing a wide variety of perspectives and disciplines, is
    essential for understanding these changes and their impact on function and
    performance.
    The functional impairment caused by aging is of primary interest. New,
    large scale studies are examining how function changes with age in an ever
    broadening range of real world situations, such as dim illumination. Some
    understanding of optical and neural contributions to the decline in vision
    function with age has been achieved. There are many potential ways to help
    offset the optical problems associated with the aging cornea and lens. As
    the understanding of the optical changes improves, the associated
    functional problems are now being addressed in novel ways. Basic scientists
    are investigating the properties of retina and support cells, looking for
    new means of preserving neural function or augmenting support.
    For any thorough understanding of aging, it is necessary to separate normal
    aging changes from the earliest signs of disease. Many of the primary
    diseases causing vision loss have increased incidence with increasing age.
    Understanding why this occurs is important in the study of vision. It is
    also crucial in combating disease. Optical means for the early detection of
    visual system or systemic disease, as distinguished from normal aging, must
    be designed based on the changes in the aging eye. Finally, if the eye is
    the window to the soul, it is also the window to blood supply and neural
    circuitry. Many systemic changes occur with age that impact on the quality
    of life, and these can be measured using novel optical techniques.
    Suggested topics include:
    Optics:
    Aging, image quality and optical aberrations
    Changes in optical properties of the lens with age and prebyopia
    Myopia and hyperopia in older eyes
    Changes in the optical properties of the cornea with age and tear film
    Aging and intraocular scattering
    Changes in the vitreous affecting image quality
    New instrumentation and techniques for anterior segment measurements in
    older adults
    Retina and retina pigment epithelium:
    Changes in the optical properties of the retina with age
    Optical measurements in aged eyes of the structure or function of the
    photoreceptor/retinal pigment epithelial complex
    Optical measurements in aged eyes of the structure or function of the
    neural retina
    Changes in the microenvironment of the retina
    Optical measurements of structure and function of the retina with aging or
    in older adults
    New instrumentation and techniques for retinal imaging in older adults
    Image analysis in the aged eye
    Changes in retinal or choroidal blood flow with aging
    Distinguishing aging from early retinal disease
    Psychophysics and function:
    Visual system limitations on human performance in older adults
    Spatial vision and aging
    Color vision and aging
    Changes with aging in dark adaptation, visual function in dim illumination
    Changes in peripheral vision
    Glare recovery
    Changes with aging in electrophysiology
    Optical limits on performance
    Changes with aging in gaze or eye movements
    New instrumentation and techniques for functional measurements in older adults
    Papers should be identified as a Aging of the Human Visual System feature
