“…We hypothesise that the conscious act of self-measuring could contribute to this difference, possibly due to the stress induced, given that anxiety or emotional stress has been documented to elevate IOP. [27][28][29] On the other hand, the act of self-measurement would mean stopping other activities and thus cessation of influencing factor and possibly leading to decreased IOP levels in some cases. Regression analyses revealed significant correlations between selfmeasurements and automated measurements on day 2, although weaker than the correlations between the automated measurements of day 1 and day 2.…”

BackgroundIntraocular pressure (IOP) monitoring in glaucoma management is evolving with novel devices. We investigated the reproducibility of 24 hour profiles on two consecutive days and after 30 days of self-measurements via telemetric IOP monitoring.MethodsSeven primary patients with open-angle glaucoma previously implanted with a telemetric IOP sensor in one eye underwent automatic measurements throughout 24 hours on two consecutive days (‘day 1’ and ‘day 2’). Patients wore an antenna adjacent to the study eye connected to a reader device to record IOP every 5 min. Also, self-measurements in six of seven patients were collected for a period of 30 days. Analysis included calculation of hourly averages to correlate time-pairs of day 1 versus day 2 and the self-measurements vers day 2.ResultsThe number of IOP measurements per patient ranged between 151 and 268 on day 1, 175 and 268 on day 2 and 19 and 1236 during 30 days of self-measurements. IOP time-pairs of automatic measurements on day 1 and day 2 were significantly correlated at the group level (R=0.83, p<0.001) and in four individual patients (1, 2, 6 and 7). IOP time-pairs of self-measurements and day 2 were significantly correlated at the group level (R=0.4, p<0.001) and in four individual patients (2, 5, 6 and 7).ConclusionsTwenty-four hour automatic measurements of IOP are correlated on consecutive days and, though to a lesser degree, with self-measurements. Therefore a virtual 24-hour IOP curve might be constructed from self-measurements. Both options provide an alternative to frequent in-office IOP measurements.
