Intraocular pressure variability in patients who reached target intraocular pressure.

摘要

AIM: To assess the intraocular pressure (IOP) variability in patients with primary open angle glaucoma (POAG) under clinical treatment who reached an established target pressure based on isolated office readings. METHODS: Retrospective analysis of 65 eyes from 65 POAG patients under clinical therapy who submitted to modified diurnal tension curve (mDTC) (measurements at every 3 hours between 8 am and 5 pm) followed by a water drinking test (WDT). All subjects had established target IOP /=17 mm Hg in 16 of 65 eyes (24.6%). Nine eyes (13.8%) presented values >/=18 mm Hg. The highest IOP detected by mDTC was 20 mm Hg in one patient (1.5%). WDT demonstrated IOP values >/=17 mm Hg in 32 of 65 eyes (49.2%). 22 eyes (33.8%) presented values >/=18 mm Hg after water ingestion. Moreover, IOP levels >/=20 mm Hg were observed in 14 eyes (21.5%). CONCLUSION: A great percentage of POAG patients undergoing clinical treatment and with IOP control based on single office measurement present significantly higher IOP measurements when performing mDTC and, especially, the WDT.
