POAG patients are shown to have markedly reduced diastolic purfussion pressure in ophthalmic artery, besides prolonged filling time of the retinal artery and vein, diminished erythrocyte deformability and increased platele...展开更多

METHODS: The B/YP and CCT were checked respectively in 72 OHT patients with normal white-on-white perimetry (W/WP) and normal optic nerve head. The B/YP was tested by Octopus 101 automated perimetry using G2 strategy, while the CCT was checked with DGH-550 ultrasound pachymeter. All patients were chosen randomly one eye for statistical analysis, a binary regression model was used to determine the independent contribution of variables included in the model, and the differences of the intraocular pressure (TOP), CCT, age, refraction and gender between the normal B/YP group and abnormal B/YP group were compared. RESULTS: Forty-nine out of 72 patients with OHT showed normal B/YP results, whereas 23 of 72 patients (31.9%) demonstrated abnormal B/YP results. CCT showed a correlation with the B/YP results (B=-0.038, SE=0.019, P=0.044), whereas none of the TOP, age, refraction and gender was found to be correlated with the B/YP results. The mean CCT in OHT patients with abnormal B/YP group was lower than that with normal B/YP group (t=2.066, P=0.043). There was a significant positive correlation between TOP and CCT (R(2)=0.513, P=0.000). CONCLUSION: The mean CCT in OHT patients with abnormal B/YP results was lower than that with normal B/YP results. There was a significant positive correlation between TOP and CCT in OHT patients. The age, refraction and gender didn't influence the B/YP results in OHT patients.展开更多
