    • Low Vision and Blindness Lois Gumataotao and Gladys Uy ED 443G: Assistive and Adaptive Technology November 5, 2008 Dr. Jacqui Cyrus
    • Objectives
      • 1. Be able to divide visual disabilities into two functional subgroups
      • 2. Discuss ways to accommodate the general education setting for students with visual disabilities
      • 3. Describe types of assistive technology that benefit people with visual disabilities at school, in the workplace and in independent living.
    • IDEA Definition
      • ...means an impairment in vision that, even with correction, adversely affects a child’s educational performance. The term includes both partial sight and blindness.
    • Two functional Subgroups
      • Low vision is also called partial sight. Sight that cannot be satisfactorily corrected with glasses, contacts, or surgery.
      • 2. Blindness or being legally blind is
the permanent loss of sight in both eyes, with a corrected visual acuity worse than 20/200 in both eyes or a field of vision less than 20 degrees in both eyes.

    • Types of Visual Loss
      • Activity 1:
      • Tunnel Vision
      • Peripheral Vision
      • Temporary Blindness
      • Peripheral vision: vision from the sides of your eyes
      • Tunnel vision:
      • vision that is directly
      • In front of you
    • Prevalence/Incidence
      • Nationally:
      • 1.3 million Americans are legally blind
      • 10 million have low vision
      • About 23,973 students between ages 6-17 receive SPED because of low vision or blindness
      • Locally:
      • GPSS is servicing 10 students that are legally blind or have visual inpairments for SY 08-09
    • Signs of Visual Problems
      • Appearance of the eyes:
      • Excessively watery
      • Are red or continually inflamed
      • Appear crusty
      • Are swollen
      • Problems with School Work:
      • The student has difficulty:
      • Reading small print
      • Identifying details in pictures
      • Difficulty distinguishing letters
    • Causes and Prevention
      • Causes:
      • Prenatal factors…heredity…accidents
      • Treatments:
      • Laser treatment, surgery, corneal implants
      • Prevention:
      • Wear protective eye gear
      • Eat vegetables high in Vitamin A
    • Activity 2
      • Due to vision loss, our other senses are enhanced.
      • Listen to the following sounds and try to identify them.
      • Identify the items in the bags through your sense of touch and smell
    • Assessment
      • Two types of eye specialists provide diagnosis and treatment:
      • Ophthalmologists (medical
      • doctors who specialize
      • in eye disorders)
      • Optometrists (professionals
      • who measure vision and
      • prescribe corrective lenses

      • Occupational therapist
      • Physical therapist
      • Orientation and mobility instructor
      • Social worker
    • Teaching Tips
      • Understand the child’s visual functioning capabilities

      • Identify visual features that enhance the child’s visual functions (color, contrast, size)
    • Accommodating for Inclusive Environments
      • Making the Classroom safe :
      • Open or close the doors fully
      • Eliminate clutter from the room, especially from the aisles and movement paths

      • Walking Canes $29.95
      • Magnifiers $30
      • Talking watches $30
      • Talking calculators
      • $8 - $300

    • Transition
      • Postsecondary Options:
      • Begin the search for the right college program
      • Register for classes as early as possible
      • Contact readers, locate assistive devices and arrange for accommodations
      • Stay in close communication with faculty
      • Transition to work:
      • Community employment during high school
      • Internships in real work settings during high school
    • Collaboration
      • Teachers should collaborate with the
      • same professionals as in early intervention
      • processes. They are experts in their fields and are able to assist for effective instruction.

    • Thought Provoking Questions
      • If a blind student refuses an auditory/oral test and insists on a braille one, yet you have no materials, what would you do?
      • What kind of classroom rules would you implement if you had all visually impaired or blind students?
      • How would you teach a blind student if the parent refuses special education?
