AIM: To determine the correlation between the disc damage likelihood scale and visual field damage in patients with open-angle glaucoma(OAG),and study the method of early diagnosis of OAG. METHODS: Optic nerves of OAG (31 cases, 58 eyes) and suspected glaucoma patients (29 cases, 58 eyes) were photographed using a digital stereoscopic camera system (Discam, Marcher, Ltd, U.K). Disc damage likelihood scale (DDLS) stages in a screen Vu stereoscope. A system of the Humphrey Field Analyzer (program 30-2, USA) was used to obtain the mean deviation (MD) and pattern standard deviation (PSD) values. The correlations between DDLS and the visual field parameters was evaluated. Findings were assessed by the Pearson correlation coefficients. RESULTS: One hundred and sixteen eyes are with moderate optic nerves (2-3 mm). In 58 eyes with open-angle glaucoma, the DDLS was significantly correlated with MD (Pearson, r = -0.664, P < 0.01) and PSD (Pearson, r = 0.554, P < 0.01). There was no significant correlation of these parameters in suspectious glaucoma patients. CONCLUSION: DDLS is significantly correlated with the degree of glaucomatous visual field damage in patients with open angle glaucoma, and thus it is helpful in early diagnosis of open-angle glaucoma.
