AIM : To evaluate the frequency of blue-on-yellow perimetry (B/YP) deficits in ocular hypertension (OHT) patients and to correlate these findings with central corneal thickness (CCT), and to investigate the influence of age, refraction and gender on the B/YP results in OHT patients.

METHODS : The B/YP and CCT were checked respectively in 50 OHT patients with normal white-on-white perimetry(W/WP) and normal ONH. 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 (IOP), CCT, age, refraction and gender between the normal B/YP group and abnormal B/YP group were compared.

CONCLUSION : Mean CCT in OHT patients with abnormal B/YP results was lower than that with normal B/YP. IOP and CCT were positively correlated in OHT patients. The age, refraction and gender didn’t influence the B/YP results in OHT patients.
