Özet:
The topics presented at the XIIIth Symposium embraced all aspects of perimetric science. A total of ten sessions were held and covered: fundamentals of perimetry, visual psychophysics, new perimetric techniques, new algorithms for estimating threshold, perimetric variability, color perimetry, optic nerve head imaging, and visual field investigation in glaucoma and in retinal and neurological disorders. The new perimetric techniques included frequency doubling technology, flicker perimetry and pupil perimetry. The new algorithms included the Swedish Interactive Threshold Algorithm (SITA) and Tendency Orientated Perimetry (TOP). The session on perimetric variability addressed some of the issues contributing to short-term fluctuation, and also contained papers on the use of univariate linear regression of point-wise sensitivity against time to follow-up for the identification of progressive visual field loss. The session on color perimetry was almost exclusively concerned with Short Wavelength Automated Perimetry (SWAP), particularly in glaucoma and high risk ocular hypertension. However, one group described a seemingly promising additional use for SWAP; namely, in the detection of diabetic macular edema. The presentations within the imaging session described the latest morphometric and topographic parameters derived by optic nerve head and nerve fiber layer analysis, and compared these structural measures with those of the functional assessment.
