Comparison between Topcon SL-45 and SL-45B with different correction methods for factors influencing Scheimpflug examination.

Topcon Tokyo manufactured the first series of SL-45 in 1980 and a second in 1982/83, which were completed in Bonn with all technical improvements developed so far. In 1987, the SL-45B was manufactured which included all previously added improvements. To compare both camera types, we carried out a test with 10 volunteers and the following technical variables for the SL-45: (1) miosis; (2) mydriasis; (3) flashbulb 1; (4) flashbulb 2; (5) film batch 1; (6) film batch 2, and (7) different types of film. Afterwards, 5 of these volunteers were photographed with the SL-45B. Photographer and reader were identical in all cases. Based on microdensitometry it could be demonstrated that, with the exception of a different film type, all variables can be compensated for by using the corneal peak as an external standard.

[Basic school problems for the physically handicapped].

Describing the current status of the "school for the physically disabled" and the developmental tendencies observable in this type of school, the author in particular contrasts recently evolved practice with the existing legislative and administrative orientations. It is found that on account of demographic and socio-medical developments and pressures, actual practice has gone far beyond the administrative framework, entailing a need to catch up in terms of conceptual thinking and administrative provision. This need to catch up essentially pertains to conceptual integration of the consequences that arise from the inclusion of students with increasingly severe disablement, to questions of occupational outlook for physically handicapped students with learning disabilities, adequate conclusions as regards creating a flexible organizational structure in the individual school, as well as the problems involved in statutory provision relative to the necessary paramedical services and the linkages between therapy and education, also in terms of cooperation between school and public health services.
