This study was conducted to determine abnormalities of the GDx glaucoma scanning system parameters in patients with tilted discs, in order to set guidelines for the evaluation of glaucomatous damage in this situation. The objective was to determine which GDx parameters displayed the highest level of variation, and which remained unchanged in tilted disc syndrome. Retinal nerve fiber layer analysis was polarimetrically conducted on 45 eyes of 26 subjects with tilted discs, and 43 normal eyes with the Nerve Fiber Analyzer II (Laser Diagnostic Technologies). All parameters except inferior maximum, average thickness, ellipse average, and inferior average displayed a significant difference between the two groups (p < 0.05). Although nerve fiber analysis is useful in the diagnosis of glaucoma, the majority of GDx parameters, as shown in this study, are unreliable in tilted disc syndrome in this respect.
