Or contact Direct Mail Works (see contact details above) by email, post, fax or phone. HTA on CD is currently free of charge worldwide.The website also provides information about the HTA Programme and lists the membership of the various committees. HTA NIHR Health Technology Assessment ProgrammeT he Health Technology Assessment (HTA) programme, now part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the costs, effectiveness and broader impact of health technologies for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined to include all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care, rather than settings of care. The research findings from the HTA Programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component of the 'National Knowledge Service'. The HTA Programme is needs-led in that it fills gaps in the evidence needed by the NHS. There are three routes to the start of projects. First is the commissioned route. Suggestions for research are actively sought from people working in the NHS, the public and consumer groups and professional bodies such as r...

“…10,11 The studies revealed wide variation of FDT performance and the reported sensitivity and specificity ranged between 19 and 99%, and 57 and 87%, respectively. [33][34][35][36][37] The novelty of DMCO compared with the previous evaluations of possible visual field tests is simply related to its free accessibility. However, continuous improvement of the website is important and necessary to implement DMCO as a diagnostic tool.…”

Purpose To evaluate Damato Multifixation Campimetry Online (DMCO), a free-of-charge internet-based visual field test. DMCO exists in three versions: DMCO BASIC, DMCO STANDARD, and DMCO ADVANCED. The main focus was (i) to investigate the sensitivity and the specificity of the existing DMCO versions in the detection of glaucomatous visual field loss and (ii) to define and evaluate algorithms for the interpretation of DMCO results. Methods The study design was an evaluation of a diagnostic test and included 97 individuals performing DMCO and whiteon-white perimetry. Interpretation algorithms were devised to define abnormality, and these were evaluated using the Glaucoma Staging System as gold standard. Receiver operating characteristic (ROC) curves and area under the ROC (AUC) were calculated. Results AUCs from 15 algorithms ranged from 0.79 to 0.90. The most promising algorithm combined results from two successive DMCO STANDARD tests. The sensitivity was highly dependent on the severity of glaucoma. Hence, for eyes with mild, moderate, advanced, and severe glaucoma, the DMCO test demonstrated a sensitivity of 11.8, 71.4, 100, and 100%, respectively. The specificity was as high as 98.1%. Median duration per eye to complete the DMCO STANDARD test was 86 s for the control group and 125 s in participants with glaucoma. Conclusions DMCO shows promise as a freeof-charge online tool to identify glaucomatous visual field defects in a preselected population. Ongoing studies are evaluating the use of DMCO in a nonselected population.

To determine the predictive value of frequency-doubling threshold perimetry for glaucoma in a population-based study. Methods: The Beijing Eye Study, a population-based study on subjects 40 years or older, included an ophthalmic examination with fundus photography and frequency-doubling threshold perimetry. Glaucoma was defined by a glaucomatous optic disc appearance. Results: The study population consisted of 4349 subjects (8615 eyes). Among 207 glaucomatous eyes (2.4%), 74 (35.7%) did not show any abnormality on frequencydoubling threshold perimetry, suggesting a diagnostic sensitivity of 64.3%. In the total study population, a visual field defect was found in 905 eyes (10.5%). In 133 (14.7%) of these eyes, a glaucomatous appearance of the optic disc was detected, and 772 eyes (85.3%) had a nonglaucomatous optic disc appearance (either normal or with nonglaucomatous optic nerve damage, retinal disease, corneal disease, or cataract). For 450 eyes (49.7%) with a visual field defect, the cause of the perimetric defect was not detected. Conclusions: In a population-based study, frequencydoubling threshold perimetry has a sensitivity of about 64% to detect glaucoma. If the result is abnormal, the probability of glaucoma is about 15%. When results of frequency-doubling threshold perimetry are abnormal, the cause of the visual field defect may not be detectable in 50% of subjects.
