PURPOSE: To compare intraocular pressure (IOP) readings of Goldmann applanation tonometry (GAT) and dynamic contour tonometry (DCT), and to correlate central corneal thickness (CCT) with these readings. METHODS: This transversal study included patients in two groups: open-angle glaucoma (OAG) and normal eyes (NE). IOP measurements were obtained in all patients using GAT and DCT. The same examiner made all GAT measurements. Another examiner, who was masked to the GAT readings, made DCT measurements. CCT was determined by ultrasound pachimetry. RESULTS: […]

PURPOSE: To evaluate the influence of the body weight and body mass index (BMI) on the intraocular pressure (IOP) peaks and fluctuation in the water-drinking test (WDT) in primary open angle (POAG) and normal tension glaucoma (NTG) patients, as well as normal eyes (NE). METHODS: Thirty-two eyes of 32 POAG patients, 30 eyes of 30 NTG patients and 20 eyes of 20 normal patients were evaluated in this transversal study. None of the patients were using antiglaucomatous drugs at the […]

PURPOSE: To evaluate intraocular pressure variation due to postural changing of supine to sitting position and, to correlate this variation with visual field defects in primary open angle and normal tension glaucoma patients, as well as normal eyes. METHODS: Thirty-two eyes of 32 POAG patients, 30 eyes of 30 NTG patients and 20 eyes of 20 normal patients were evaluated in the study. Intraocular pressure was measured at 6 o’clock in supine position and 5 minutes after in sitting position […]
