Clinical data; Demographic details and clinical data including diagnosis, years with glaucoma, highest known IOP by Goldmann applanation tonometer, cup-to-disc ratio (CDR), CH parameters and global indices from qualifying visual field. Results: Mean corneal hysteresis (CH) was lower in the primary open angle glaucoma patients. Conclusions: Corneas in glaucomatous patients have weaker biomechanical properties ER -
