Diagnostic ability of different tools for detection of glaucoma with confocal scanning laser tomography (Heidelberg Retina Tomograph II).

We evaluated the diagnostic ability of various diagnostic tools to detect glaucomatous damage in 101 normal eyes and 102 glaucomatous eyes. Mikelberg's linear discriminant function (LDF) obtained the best sensitivity followed by our own four formulas. With respect to specificity, Burk's LDF showed better results than Mikelberg's LDF and our formulae. Several Heidelberg retina tomograph analysis tools are useful to discriminate healthy from patients with glaucoma. Alternative tools based on normative databases derived from different autochthon populations add evidence needed to support their global use.
