.03). SBP and DBP were significantly lower for sevoflurane than for ketamine at all
measurements from two minutes onward, and HR was lower for sevoflurane than for
ketamine at two, four, and six minutes.
CONCLUSIONS: IOP measured after ketamine sedation is more likely to represent the
awake IOP than that after sevoflurane anesthesia. Changes in SBP, DBP, and HR
caused by sevoflurane suggest that hemodynamic alterations may underlie its effects
on IOP.

PURPOSE: To study the effect of extraocular muscle surgery on intraocular pressure
(IOP) in patients with thyroid-associated ophthalmopathy.
METHODS: The medical records of patients with restrictive myopathy secondary to
thyroid-associated ophthalmopathy who underwent strabismus surgery from July 1,
1997 through July 31, 2003 were reviewed and analyzed retrospectively. Seventeen
patients met the criteria and were included in this study. All patients were seen at the
Thyroid Eye Center at the University of California, San Diego, a university-based tertiary
referral center. The main outcome measure was IOP readings obtained before and after
surgery in both primary gaze and upgaze.
RESULTS: A statistically significant decrease in IOP in upgaze was noted after
extraocular muscle recession. The mean IOP before surgery was 16.6 +/- 3.78 mm Hg
in primary gaze and 23.2 +/- 7.27 mm Hg in upgaze. After strabismus surgery, the mean
IOP after one month was 15.7 +/- 2.36 mm Hg (P = .215) in primary gaze and 18.9 +/-
2.96 mm Hg in upgaze (P = .001).
CONCLUSIONS: Strabismus surgery resulted in a significant reduction in IOP in the
early postoperative period in patients with restrictive myopathy secondary to thyroidassociated
ophthalmopathy.
