Preschool vision screening Sarah K Snowdon Sarah L Stewart-Brown Health Services Research Unit, Department of Public Health, University of Oxford Final manuscript received April 1997 Published September 1997 This report should be referenced as follows: Snowdon SK, Stewart-Brown SL. Preschool vision screening. Health Technol Assessment 1997; 1(8). NHS R&D HTA Programme he overall aim of the NHS R&D Health Technology Assessment (HTA) programme T is to ensure that high-quality research information on the costs, effectiveness and broader impact of health technologies is produced in the most efficient way for those who use, manage and work in the NHS. Research is undertaken in those areas where the evidence will lead to the greatest benefits to patients, either through improved patient outcomes or the most efficient use of NHS resources. The Standing Group on Health Technology advises on national priorities for health technology assessment. Six advisory panels assist the Standing Group in identifying and prioritising projects. These priorities are then considered by the HTA Commissioning Board supported by the National Coordinating Centre for HTA (NCCHTA). This report is one of a series covering acute care, diagnostics and imaging, methodology, pharmaceuticals, population screening, and primary and community care. It was identified as a priority by the Population Screening Panel (see inside back cover). The views expressed in this publication are those of the authors and not necessarily those of the Standing Group, the Commissioning Board, the Panel members or the Department of Health.
