Purpose: To find out relationship of mean ocular perfusion pressure(MOPP), Systolic ocular perfusion pressure (SPP) & diastolic ocular perfusion pressure with occurrence of primary open angle glaucoma(POAG) Study Design: Hospital based cross sectional study Study period: August '2016-February '2017. A period of 6 months. Setting: Sankara eye hospital, krishnankoil, tamilnadu. Method: In a period of 6 months we examined total 836 patients of 40-80 years age group from southern part of Tamilnadu,

... of which 431 patients were male & 405 were female. All patients are evaluated with dilated fundus bio microscopy with +90D lens,IOP measurement by applanation tonometer,gonioscopy by goldman 4 mirror goniolens& Humphrey 30-2 perimetry test. Only primary open angle glaucoma patients were included. Blood pressure was checked in each patient with digital BP measuring instrument. OAG risk. Lower DBP (OR= 1.65; 95% CI, 1.12 -2.82, comparing persons in the lowest quartile with those in highest quartile [Q1 vs. Q4] of DBP), lower MOPP (OR=1.63; 95% CI, 1.02-2.85; [Q1 vs. Q4]) and lower DPP (OR,=1.56; 95% CI, 1.23-2.92; [Q1 vs. Q4]) were significantly associated with OAG risk. Higher SBP wasnot associated with increased risk of glaucoma(p= 0.64)
