Abstract

Purpose

To compare the postoperative intraocular pressure (IOP) of eyes following pars plana vitrectomy (PPV) combined with intravitreal silicone oil (SO) tamponade by Corneal Visualization Scheimpflug Technology (CST), Goldmann applanation tonometry (GAT) and non-contact tonometry (NCT).

Methods

Thirty-eight participants who had undergone PPV combined with SO tamponade to treat vitreoretinal diseases were enrolled. Postoperative IOP measurements were obtained using CST, NCT and GAT. Inter-device agreement was assessed by Bland–Altman analysis. The correlation coefficient was used to describe the potential postoperative factors affecting the postoperative IOP differences between each device.

Results

Bland–Altman analysis revealed the bias between CST and GAT, between CST and NCT, and between GAT and NCT to be −0.2, 2.1 and 2.4 mmHg, respectively. CST and GAT correlated well with each other. NCT values were lower than those of GAT and CST (all p < 0.05), whereas CST values did not differ from the GAT readings. Central corneal thickness, corneal biomechanical properties and age showed significant correlation with the differences of CST–NCT and GAT–NCT.

Conclusions

In SO tamponade eyes, NCT obtains lower IOP than other tonometry techniques, and CST is highly consistent with GAT. CST offers an optional non-contact method for measuring postoperative IOP in SO tamponade eyes.
