Abstract: | Background: The purpose of this study was to assess ocular hemodynamics in patients with unilateral tilted disc syndrome (TDS) using color Doppler ultrasonography (CDUS). Methods: Fifteen consecutive patients with unilateral TDS and normal-appearing contralateral optic nerves were enrolled. Both eyes of all participants underwent detailed ophthalmological examination including automated visual field testing. CDUS was performed in the eyes with tilted discs and fellow unaffected eyes. Peak systolic velocities, end diastolic velocities, and vessel resistance were measured in the ophthalmic artery (OA), central retinal artery (CRA), nasal posterior ciliary artery (NPCA), and temporal posterior ciliary artery (TPCA). The minimum and maximum blood flow velocities were also measured in the central retinal vein (CRV). Results: No statistically significant differences were found between eyes with tilted discs and fellow normal eyes in terms of OA, CRA, NPCA, or TPCA mean peak systolic or end diastolic velocities, resistivity indices, and the mean maximal and minimal CRV blood flow velocities. Conclusion: Ocular hemodynamic measurements determined by CDUS do not appear to be altered in tilted disc syndrome.
