Circadian (24-hour) Pattern of Intraocular Pressure and Visual Field Damage in Eyes with Normal-Tension Glaucoma

Abstract

In the 177 NTG patients, there was a significant nighttime elevation of habitual-position IOP, and nocturnal seated IOP was significantly less than nocturnal habitual-position IOP. Subgroup analysis indicated three distinct daily patterns of peak IOP in the patients. There was no relationship between nocturnal elevation of habitual IOP and the magnitude of VF damage.
