BACKGROUND AND OBJECTIVE: To investigate retinal nerve fiber layer thickness and optic disc parameters in eyes with tilted disc syndrome. PATIENTS AND METHODS: Thirty-eight eyes with tilted disc syndrome (20 myopic control eyes, and 20 emmetropic control eyes) were examined. After a routine ophthalmologic examination of all eyes, scanning laser polarimetry (for retinal nerve fiber layer thickness) and scanning laser tomography (for optic disc parameters) were performed. Scanning laser polarimetry and scanning laser tomography parameters were compared in the different groups. RESULTS: On scanning laser polarimetry evaluation, statistically significant differences were found in the superior integral, nasal integral, and superior nasal quadrants of eyes with tilted disc syndrome compared with control groups (P = .01, P = .04, P = .00, P = .00, P = .00, and P = ,00, respectively). On scanning laser tomography evaluation, statistically significant differences were found in average diameter, total contour area, effective area, average depth, volume above, neuroretinal rim area, and cup-disc ratio in eyes with tilted disc syndrome compared with control groups (P = .00, P = .00, P = .00, P = .04, P = .02, P = .00, and P = .01, respectively). CONCLUSION: Parameters acquired through imaging with scanning laser polarimetry and scanning laser tomography in eyes with tilted disc syndrome are different from those of normal eyes.
