Expert agreement in evaluating the optic disc for glaucoma.

摘要: The authors studied intraobserver and interobserver agreement, under monoscopic stereoscopic conditions, in estimating vertical cup-to-disc ratios assessing whether a disc had glaucomatous damage. Six glaucoma experts evaluated 75 optic photographs both viewing conditions. also re-evaluated 25 photographs. Intraobserver agreement cup-to was high (median weighted kappa, 0.79). Interobserver cup-todisc moderate (stereoscopic median 0.67); individual differed by as much 0.2 diameters (DD) monoscopically 0.16 DD stereoscopically. observers estimated larger when evaluating the same discs conditions than damage substantial 0.76). 0.50). This study confirms ability of to reliably evaluate within themselves emphasizes need for developing standardized methods evaluation glaucoma.
