AIM: To compare the difference of prevalence of peripapillary atrophypzone (pzone) of normal, primary open angle glaucoma (POAG) and primary angle-closure glaucoma( PACG) subjects . METHODS:Of matching age and refract error,135 right eyes of 135 normal subjects, 101 eyes of 58 POAG subjects, 81 eyes of 50 PACG subjects were selected. The color optic disc fundus photographs (30(degrees)) of subjects were collected with Heidelberg color fundus camera. Vertical cup/disc diameter of the glaucoma groups were calculated with computer software,then the prevalence of pzone and vertical cup/disc diameter ratio were analyzed with Chi-square test. RESULTS: The prevalence of pzone in the normal, POAG,PACG group was 23.0%, 69.3%, 49.4% respectively. (X(2) = 51. 3, P = 0. 000). The prevalence of pzone of POAG was higher than that of PACG (^ = 7.5, P = 0.005). In the three groups, the prevalence of horizontal temporal section was highest in the four section and the nasal section had the lowest prevalence (x (2)= 19.4, P = 0.000: X(2) = 50.3,P=0.000:X(2) =11.7,P = 0.009). In the POAG group, the prevalence of pzone of serious optic nerve damage group was higher than that of the minor group (x(2)=14.0, P= 0.000). In the PACG group, the prevalence of pzone between serious optic nerve damage group and the minor group was not different(X(2) =0.6,P = 0.287). CONCLUSION: The prevalence of pzone of POAG and PACG are both higher than that of normal group. The prevalence and the area of pzone of POAG is higher than that of PACG. The prevalence of pzone of serious optic nerve damage group is higher than that of the minor group. LA: Chinese
