Abstract
Objectives: The aim of this study was to compare sonoelastographic findings in the retina– choroid–sclera (RCS) complex and vitreous in glaucomatous and healthy eyes.
Methods: For this cross-sectional comparative study, 20 patients with primary open-angle glaucoma (POAG) and 20 healthy volunteers were recruited. Ultrasound elastography measurements were taken with a sonographic scanner of the RCS complex, anterior vitreous (AV), posterior vitreous (PV), retrobulbar fat tissue (RFT), optic disc, and optic nerve in each eye.
Results: The elasticity index of the RCS complex, RFT, optic disc, optic nerve, AV, and PV were similar in both groups (p > 0.05), though the AV/PV strain ratio in the group of patients with glaucoma was significantly higher (p = 0.04).
Conclusion: Glaucoma increases the AV/PV strain ratio. In providing reproducible and consistent values, the real-time elastography technique may be helpful in elucidating the mechanisms of glaucoma in some aspects.
