Hi, Its Kim here, I have oculo cutaneous albinism (type 2) and I live near Sydney in Australia and i am very interested in the introduction of bioptic driving in australia. I have been speaking to simon who runs this site and i will be developing a site for australia linked to this one for australians interested in getting bioptic driving happenning! I will need lots of support and help from all those interested in making this a reality! So until things are up on a web page please email me with expressions of interest on kimmy@idx.com.au talk soon kim

Measuring the effectiveness of BiOptic telescopes for persons with central vision loss. Szlyk JP, Seiple W, Laderman DJ, Kelsch R, Stelmack J, McMahon T. Department of Research and Development, Chicago VA Health Care System, UIC Eye Center, University of Illinois at Chicago College of Medicine, 60612, USA. PURPOSE: 1) To evaluate a vision rehabilitation program aimed at training persons with central vision loss to use a bioptic telescope for improving life skills, including driving and 2) to compare the outcomes of subjects who are given bioptic telescopes and training, with subjects who are prescribed telescopic lenses without training. METHODS: Twenty-five subjects ranging in age from 16 to 78 years were included in the study. Each subject was randomized to one of three groups: Group 1 received bioptic telescopes and training during the first approximately 3-month-long period of the approximately 6-month-long study; Group 2 received lenses and training during the second approximately 3-month-long period of the study; and Group 3 received the lenses for approximately 3 months without any training. An assessment battery consisting of clinical vision tests, functional tasks evaluated by an orientation and mobility specialist, driving skills evaluated by a kinesiotherapist specializing in driver's education, and psychophysical measures was administered to Groups 1 and 2 at baseline, and at approximately 3 and 6 months, and to Group 3 at baseline and at approximately 3 months. The tasks were categorized into 6 major functional categories: Recognition, Mobility, Peripheral Identification, Scanning, Tracking, and Visual Memory. Training consisted of 5 weeks of laboratory-based training focusing on skills within these 6 categories, and 8 weeks of on-road driving training. RESULTS: There was significant improvement in all task categories with use of the telescopes. There was improvement in all task groups with training, though a significant difference between the trained and untrained groups existed only in the Recognition, Peripheral Identification, and Scanning Categories, but not in Mobility, Tracking, or Visual Memory. When the tasks involving driving-related skills were analyzed separately, training also had a significant effect. CONCLUSION: There was significant improvement in visual skills with the use of a bioptic telescope. This improvement was greater with training in the use of the lenses in a number of visual skills categories including driving-related skills.
