Sequential changes in intraocular pressure (IOP) according to the operated muscle in patients with thyroid eye disease (TED). The surgical procedures for strabismus performed on all patients consisted of medial rectus (MR) recession, inferior rectus (IR) recession, and superior rectus (SR) recession. There were similar patterns of sequential change in the IOP during strabismus surgery among the three muscles. A repeated-measure ANOVA analysis showed statistically significant group-by-time effects for the change of IOP among the three muscles during surgery (p < 0.001). The mean IOP of MR were higher during surgery compared with those of other two muscles (p = 0.027 with IR recession; p = 1.000 with SR recession). The mean IOP of IR were lower during surgery compared with those of other two muscles (p = 0.051 with SR recession)
