Corneal thickness and daily curve of intraocular pressure in suspected and glaucomatous patients
PURPOSE: To evaluate in suspected and glaucomatous patients the correlation between central corneal thickness (CCT) and intraocular pressure (IOP), measured during the daily curve of intraocular pressure (DCPo), including CCT and IOP measurements in bed at 6 am. The ocular axial length was also compared. METHODS: 114 eyes from 73 patients, 30 eyes suspected of glaucoma (group I) and 84 eyes with chronic open-angle glaucoma (group II) were prospectively studied. Both groups were subjected to DCPo with measurements of IOP at 9 am, 12 pm, 6 pm, 10:30 pm and on the next day at 6 am in bed and in darkness before the patient gets up. Using the ultrasonic DGH 5100® device, CCT measurements were performed at 9 am, 6 pm, 10:30 pm and the next day at 6 am in bed before the patient gets up. The ocular axial length was also measured. RESULTS: In the total sample and, separately in each group, the mean IOP was more elevated in bed at 6 am. There were no significant CCT changes during the day within each group or between both groups. No statistically significant difference was found between the mean ocular axial length of both groups. CONCLUSIONS: In suspected and glaucomatous patients, there were no statistically significant CCT variations during the day; therefore, only one CCT measurement is sufficient. Also, there was no statistically significant difference between ocular axial length of both groups.
