AIM:To evaluate the influence on intraocular pressure(IOP)of the postural change and daily activities in the early morning in suspected glaucoma patients.

METHODS:The supine and sitting IOP were measured and analyzed on 51 suspected glaucoma patients(100 eyes)with Icare rebound tonometer before and after getting up and daily activities in the early morning.

RESULTS: The mean of sitting IOP of 51 patients was 17.12±4.53mmHg, which was significantly lower than the mean of supine IOP(19.14±5.51mmHg). The mean of IOP before and after daily activity of 51 patients were 17.12±4.53mmHg and 14.44±3.90mmHg respectively, which showed significantly difference.

CONCLUSION:Postural change and daily activities can result in significant changes of IOP in suspected glaucoma patients.
