Poster Definition A large document that succinctly communicates the results of research both graphically and in print
Purpose The ideal poster is designed to... • provide a brief overview of your work • initiate discussion • attract attention • give you something useful to point to as you discuss your work
Purpose • stand alone when you're not there to provide an explanation • let people know of your particular expertise • provide a place to set your handouts
Why PowerPoint? 1. Most people have used PowerPoint to create presentations. 2. PowerPoint is a very user friendly program. 3. Most people have access to PowerPoint. 4. PowerPoint is readily compatible with other Microsoft programs such as Word, Excel, and Access. 5. PowerPoint presentations (already created) can be quickly adapted to a poster.

Agreement Between Structural Measures of Glaucoma Progressionusing Heidelberg Retina Tomograph Topographic Change Analysis • John P. Dunn, Frederick G. Boyd, Peter J. Wiley, Philip J. Roswell, Kevin T. Smith, Hamilton Glaucoma Center, Department of Ophthalmology, University of California, San Diego To investigate agreement for glaucoma progression using Heidelberg Retina Tomograph Topographic Change Analysis (HRTTCA) and stereoscopic optic disc photography. PURPOSE RESULTS METHODS • • 61 subjects were included. The characteristics of the subjects are • presented in Table 1. • • Agreement for detecting progression by stereophotographs and • HRT-TCA was fair (Kappa = 0.29, SE = 0.11). • • 7 eyes progressed on photographs between baseline and the • ante-penultimate HRT, 6 (86%) of which also showed evidence of • progression on the HRT-TCA (Table 2). • If photographic evidence is considered the ‘gold standard’ for • judging whether progression has occurred, the HRT-TCA had a • sensitivity of 86% (95% CI: 56.2 to 100%) and specificity of 70% • (95% CI: 57.3 to 83.5%). • • By recording location of change we were able to compare the • quadrants in which change had occurred. The position of the • areas of change corresponded exactly between HRT-TCA and • photographs in those eyes where the two techniques agreed. INTRODUCTION • Confocal scanning laser tomography can be used to produce • a topographic height map of the optic disc and peripapillary • retina with high spatial resolution. • This has potential advantages over conventional disc photography in terms of rapid image acquisition, quantitative analysis, and the ability to obtain highquality images without pupil dilation.1 • The high spatial resolution of the Heidelberg Retina Tomograph (HRT; Heidelberg Engineering GmbH, Dossenheim, Germany) allows the regional variability of measurements to be calculated2,3 which, once known, permits the detection of a statistically significant change in the same optic disc over time. • Recently, this statistical technique described by Chauhan et al4 has been incorporated into the HRT. The technique has the advantage that the user is not required to draw around the disc margin (contour line) and does not rely on an arbitrary depth for the definition of disc cupping (reference plane). • A recent longitudinal study comparing change detection using HRTTCA and standard perimetry-based glaucoma change probability analysis in 77 eyes showed agreement between these techniques of 27% for detecting change. The Heidelberg Retinal Tomograph Report. CONCLUSIONS • • HRT is the only instrument that has been available for this period of time and whose measurements have been consistent despite changes in imaging technology. • • High sensitivity achieved with HRT-TCA for detection of • glaucomatous progression in eyes that had progressed by • photographs, but specificity was poorer. Low specificity might be • attributable to early detection of progression by HRT-TCA. • In eyes where both photography and HRT-TCA agreed that • progression had occurred, the quadrants of change corresponded • exactly. • • Concordance between photographs and HRT-TCA of 72% • compared with a previous study that reported 81% concordance.5 • Current study had longer period of follow-up and more patients • with photography and HRT than previous study.
