This study evaluated the effects of providing comprehensive low vision services to elderly persons with visual impairments in New Zealand. The 93 participants were matched on age, gender, and visual function with 93 who did not have access to comprehensive low vision services. No significant differences were found between the groups at posttest and follow-up on the three primary dependent variables of visual function, instrumental activities of daily living, and quality of life.

The records of 1,661 children and adolescents who received 3,188 clinical low vision evaluations from a single examiner at low vision clinics sponsored by the Iowa Braille School over a 22-year period were surveyed to determine the characteristics of this population. The factors that were reviewed included age, sex, ocular condition, best-corrected vision at far and near, habitual working distance, and recommended optical devices.
