Variability of intraocular pressure measurements in observation participants in the ocular hypertension treatment study.

ABSTRACT:

Purpose

To describe variability of intraocular pressure (IOP) measurements within the same eye and between right and left eyes over a 60-month period in participants in the Ocular Hypertension Treatment Study.

Design

Analysis of data from a prospective, randomized clinical trial.

Participants

Eight hundred ten participants randomized to the observation group.

Methods

Intraocular pressure measurements were obtained at the baseline visit and every 6 months thereafter. Pearson correlation coefficients were calculated for IOP measurements in the same eye between visits and for IOP measurements between right and left eyes of participants at each visit. Differences in IOP measurements between visits are reported in percent change (>15%, >20%, and >30%) and in millime
