Correlation between Intraocular Pressure Fluctuation with Postural Change and Postoperative Intraocular Pressure in Relation to the Time Course after Trabeculectomy.

Hirooka K, Tenkumo K, Nitta E, Sato S - J Ophthalmol (2014)

Bottom Line: Postural IOP changes were less than 3 mmHg in those patients who did not require needle revision at every visit.However, in patients who did require needle revision, the increase in the posture-induced IOP was greater than 3 mmHg prior to the increase in the sitting position IOP.Conclusions.

ABSTRACT
Background. To investigate the correlation between intraocular pressure (IOP) fluctuation with postural change and IOP in relation to the time course after trabeculectomy. Methods. A total of 29 patients who had previously undergone primary trabeculectomy with mitomycin C were examined. IOP was obtained at 1, 2, 3, 6, and 12 months and then every 6 months postoperatively. Results. The postural IOP difference before surgery was 3.0 ± 1.8 mmHg, which was reduced to 0.9 ± 1.1 mmHg at 1 month, 1.0 ± 1.0 mmHg at 2 months, 1.3 ± 2.0 mmHg at 3 months, 1.3 ± 1.4 mmHg at 6 months, 1.4 ± 1.5 mmHg at 12 months, and 1.1 ± 0.7 mmHg at 18 months after trabeculectomy (P < 0.01 each visit). The filtering surgery failed in 7 out of 29 eyes. Postural IOP changes were less than 3 mmHg in those patients who did not require needle revision at every visit. However, in patients who did require needle revision, the increase in the posture-induced IOP was greater than 3 mmHg prior to the increase in the sitting position IOP. Conclusions. Assessment of postural IOP changes after trabeculectomy might be potentially useful for predicting IOP changes after trabeculectomy.

Mentions: Figure 1 shows the correlation between the Goldmann applanation tonometer and ICare on subjects in the sitting position at baseline. Both were in close agreement with a correlation coefficient of 0.86 (P < 0.001).
