PURPOSE: To characterize twenty-four-hour pattern of IOP in patients with primary open-angle glaucoma (POAG). METHODS: Thirty persons of 40 to 65 years were selected in patients with POAG group. IOP were measured with Tono-pen tonometer within 24 hours. Measurements were taken every 2 hours in each eye (12 times in 24 hours). Both the sitting IOP and the supine IOP were measured between 7:00 and 23:00 (once in 2 hours). RESULTS: In both volunteers and patients with POAG, The lowest IOP occurred in 17: 30, the peak IOP occurred at 1:30. The value between trough and peak in twenty-four-hour pattern of the sitting and supine IOP was higher than the supine IOP. CONCLUSIONS: The peak of IOP in most of patients with POAG occureed in the period of the sleeping time at night. Nocturnal intraocular of the patients with POAG pressure should be paid more attention. LA: Chinese
