AIM: To determine the correlation of disc damage likelihood scale (DDLS) with optic disc parameters measured with Heidelberg retina tomograph II (HRT-II) in patients with primary open-angle glaucoma (POAG). METHODS: The vertical diameter of optic disc of 48 patients (92 eyes) with POAG was measured with + 90D lens under slit lamp microscope. DDLS was recorded according to the criteria formulated by the scale. The optic disc parameters of the participants were measured with HRT-II. The correlation of DDLS with rim area (RA) and rim volume (RV) were evaluated. The data were assessed by the correlation coefficients. RESULTS: There was strong negative correlation between DDLS and RA ( = -0.835, P < 0.01). There was negative correlation between DDLS and RV (r = -0.697, P < 0. 01) also. There was positive correlation between DDLS and the glaucomatous stage of the patients (r = 0.804, P < 0.01). CONCLUSION: There is a significant correlation between DDLS and the optic disc parameters measured with HRT-II in patients with POAG.
