A High School Equivalency Program for Visually Impaired Students

The instruction includes the teaching of math, spelling and grammar, literature, history, and science. The use of various materials, special aids and modifications for visually impaired students is discussed.

Some delays in visual-motor activities were found, as well as differences in the sequence of acquiring skills. The subgroup of visually impaired children with multiple handicaps acquired milestones at a slower rate than did the subgroup of visually impaired children with no additional handicapping conditions.

Visual deficits are often first detected through required preschool vision screenings. These screenings vary in their comprehensiveness and administration. No standardization for testing or administration exists. Referrals for further examination appear to be higher for those children receiving a thorough battery, suggesting that some of the testing procedures used have inappropriately high rates of false negatives.

Apparently, oxygen administration alone does not account for all these ROP babies. Birth-weight, gestational age, and duration of administration of oxygen are primary contributors to ROP development. The stages of severity range from no visual damage to total blindness. Treatments are either pharmacological or surgical. Vitamin E therapy, photocoagulation procedures, cryotherapy, scleral buckling procedures, and vitrectomy are common treatments, but none is totally successful in ameliorating this condition. The educational problems of children with ROP parallel those of other visually impaired children, with deficits found primarily in exploration, mobility, and language. Referral to early intervention programs can provide a comprehensive structured learning situation and support to the entire family.

Although distance learning has been in existence since 1920, its application to the preparation of teachers is more recent. In 1998, 44% of all institutions of higher education offered distance education courses, and the number continues to rise (Huebner & Weiner, 2001). The implementation of a distance learning model for preparing teachers of students with visual impairments is the direct result of a national shortage of such teachers and the limited accessibility of teacher preparation programs throughout the country (Cooper

Twenty-two hospitals were surveyed. Approximately .33 percent of the children born at these hospitals were diagnosed and classified as multiply impaired. Of these, 44 percent had visual impairments. Forty-nine preschool programs for the multihandicapped were also surveyed. Many of the children in these programs had not been registered as visually impaired, but instead had been classified according to their other disabilities. Of the preschool population, 9.3 percent were multiply impaired, with one of the impairments being a visual disability, and an additional .8 percent were identified as being visually impaired alone.

Diabetic retinopathy, senile cataracts, senile macular degeneration and glaucoma are the leading causes of blindness in elderly persons. Environmental modifications, such as levels of illumination and reduction of glare, can enhance an individual's ability to function in society. The nursing home population needs to pay attention to environmental factors as well as standardization of procedures for vision assessment. Much work is needed to develop programs to properly screen and treat the visual problems in elderly persons.
