Abstract
OBJECTIVE: Our aim is to measure the stiffness values in different regions of the eye with shear wave elastography (SWE) in patients with glaucoma and to compare the results with healthy eyes to investigate whether there is a change in the elasticity of the ocular compartments in glaucoma patients.MATERIAL AND METHODS: In this study, we compared 12 patients with open-angle glaucoma and 32 healthy volunteers using an SWE-equipped ultrasonography device. Only the right eye was evaluated in all patients. First, the eye globe was generally examined in B-mode. Then, the stiffness values of the optic nerve head, retro-orbital nerve, sclera-retina complex and retro-orbital adipose tissue in the posterior segment and the stiffness values of the cornea, lens and anterior chamber in the anterior segment of the eye were measured with SWE in kiloPascal and both groups were compared statistically.RESULTS: No statistically significant differences were found between the patient and control groups in terms of the stiffness values recorded in the measurements performed in different parts of the eye.CONCLUSIONS: Although SWE is an easily applicable method, no significant differences were found between glaucoma and control groups. However, thanks to this study, reference values for different parts of the eye in normal individuals have been determined.
