The Ocutech Vision Enhancing System (VES): utilization and preference study.

An NIH-sponsored user and prescriber preference trial was conducted comparing a new low vision telescope system, the Ocutech Vision Enhancing System (VES) to two conventional Keplarian spectacle telescope systems in a controlled cross-over clinical study performed at four independent low vision clinics. Fifty-five visually impaired individuals, 18-81 years of age, with both previous and no telescope experience, were followed for 8-16 weeks. The experimental and control devices were compared on a series of subject-selected visual tasks using a standardized clinical protocol. Subjects were trained in the use of the systems with standardized clinical methods. The data shows a statistically significant preference of the new design by both patient and clinician with the overriding factors relating to appearance, weight, adjustability and the fit of the frame.

Chemoimmunotherapy for maintenance in acute myeloblastic leukemia.

Of 30 adult patients with acute myeloblastic leukemia, 14 achieved complete remission. Eight of these were given chemoimmunotherapy for maintenance. The immunotherapy consisted of intradermal pooled allogeneic leukemic cells (snap-frozen irradiated) and BCG vaccine given by Heaf gun, given twice in 4 weeks. The chemotherapy was given for 1 week in 4 weeks. The median duration of remission in these eight patients was 115+ weeks and the median duration of survival was 147+ weeks. The other six patients who were given chemotherapy only for maintenance had a median duration of remission of 15 weeks and a median survival of 52 weeks. The two groups cannot be compared properly, however, as allocation of patients was not random, and the chemotherapy differed significantly.
