Baseline IOP and OPP levels were compared to those during active treatment with TZ and 3 days after stopping the medication. OPP was calculated as 2/3 [diastolic BP + 1/3 (systolic BP – diastolic BP)] – IOP.Results: TZ significantly reduced the mean diurnal and nocturnal IOP levels compared to baseline at all time points. During treatment, mean IOP decreased from 17.1±3.4 to 14.7±3.0 mmHg during the diurnal period (P<0.01) and from 19.9±3.6 to 18.8±3.5 mmHg during the nocturnal period (P<0.01). Once treatment was discontinued, mean IOP remained at levels significantly less than baseline during both the diurnal (15.6±3.2 mmHg) and nocturnal (18.7±3.7 mmHg) periods. Mean OPP was not significantly changed with treatment during either period. Conclusion: In this population of NTG patients, TZ significantly lowers IOP at all time points throughout the diurnal and nocturnal periods. The treatment effect on IOP endures for up to 3 days after the last dose. Treatment did not significantly improve OPP.Keywords: ocular perfusion pressure, intraocular pressure, 24-hour, diurnal, nocturnal, sofZia®Seibold LKKahook MYDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2014, Iss default, Pp 2189-2193 (2014)
