Figure 1.

Comparison of the total proportion of eyes with elevated IOP among the different tamponade groups.

Notes: The proportion of eyes with elevated IOP was significantly higher in the silicone oil group than in the others group (combined air, BSS, and SF6 groups; P=0.002, Pearson’s χ² test). The proportion of eyes with elevated IOP was significantly higher in the C3F8 group than in the others group (P=0.034, Pearson’s χ² test). There was no significant difference in the proportion of eyes with elevated IOP between the silicone oil group and the C3F8 group (P=0.166, Pearson’s χ² test). ^*Significant; ^**highly significant.

Abbreviations: SF6, sulfur hexafluoride; C3F8, perfluoropropane; BSS, balanced salt solution; IOP, intraocular pressure; NS, not significant.
