Abstract     BACKGROUND. Glaucoma defined as progressive optic ncuropathy with optic nerve head (ONH) changes and visual field loss is one of the leading causes of irreversible blindness. Morphology of the ONH is of importance in the diagnosis and follow up of glaucoma and its changes often precede the onset of visual field defects. In contrast to ophthalmoscopy of the ONH which shows wide variation among observers, the new imaging devices enable quantitative and objective interpretation of the ONH appearance. To evaluate glaucomatous eyes it is necessary to obtain reliable comparative data and study the topographic morphology of the ONH in normal eyes. AIM. To study the ONH characteristics with confocal scanning laser tomography using the Heidelberg retina tomograph (IiRI') and retinal thickness analyser (RTA) and thereby to obtain database for comparison of healthy and glaucomatous eyes. Our aim was also to determine the repeatability (reproducibility) of measurements of HRT and RTA and to investigate the agreement of measurements between the two methods and define their clinical usefulness. HYPOTHESIS. We tested the hypothesis that ONH measurements across parameters obtained in our study are comparable to the nonnal data included in the HRT and RTA software, that measurements obtained by HRT and RTA are reproducible and also that there is good clinical agreement benveen the two methods that can be used interchangeably. METHODS. Fifty healthy volunteers (55,5 +- 9,5 years) of both sexes with no history of ocular pathology were recruited from the outpatients requiring presbyopic correction. ONH imgaing was performed with HRT and followed by RTA. (Abstract truncated at 2000 characters).
