To evaluate the effect of an eyelid speculum on intraocular pressure (IOP) measurements in newborns.
A total of 54 eyes of 27 newborns were involved in the study. The IOP measurements were obtained under topical anesthesia with the Icare PRO (Icare Finland Oy) before and after inserting the infant type of Barraquer wire eyelid speculum. A paired test was used to compare the measurements.
The mean IOP without the eyelid speculum was 9.04 ± 2.13 mm Hg (range: 6.00 to 13.20 mm Hg) in the right eye and 9.26 ± 1.59 mm Hg (range: 7.10 to 13.00 mm Hg) in the left eye. With the eyelid speculum in place, the mean IOP was 11.91 ± 2.23 mm Hg (range: 9.10 to 15.80 mm Hg) in the right eye and 11.70 ± 1.89 mm Hg (range: 8.40 to 14.50 mm Hg) in the left eye ( ≤ .001). The mean differences in IOP between measurements with and without the eyelid speculum were 2.87 ± 2.23 mm Hg (range: 0.20 to 5.20 mm Hg) in the right eye and 2.44 ± 1.48 mm Hg (range: 0.00 to 4.90 mm Hg) in the left eye. The mean difference in IOP between measurements with and without the eyelid speculum for all eyes was 2.65 ± 1.89 mm Hg (range: 0.00 to 5.20 mm Hg). There was no correlation between the difference in IOP after the placement of the eyelid speculum and postconceptual age or weight at the examination ( = 0.11, = .41, = 0.32, = .14, respectively).
The Barraquer wire eyelid speculum caused an increase in IOP in newborns under topical anesthesia without a significant difference between postconceptual age and sex in both eyes. The average IOP rise after the eyelid speculum was inserted was 2.65 mm Hg. This effect should be considered when interpreting IOP measurements in newborns. .
评估眼睑拉钩对新生儿眼内压（IOP）测量的影响。
本研究纳入了 27 例新生儿的 54 只眼。在局部麻醉下使用 Icare PRO（Icare Finland Oy）进行 IOP 测量，然后插入婴儿型 Barraquer 金属丝眼睑拉钩。采用配对 t 检验比较测量结果。
右眼无眼睑拉钩时的平均 IOP 为 9.04 ± 2.13 mm Hg（范围：6.00 至 13.20 mm Hg），左眼为 9.26 ± 1.59 mm Hg（范围：7.10 至 13.00 mm Hg）。使用眼睑拉钩时，右眼的平均 IOP 为 11.91 ± 2.23 mm Hg（范围：9.10 至 15.80 mm Hg），左眼为 11.70 ± 1.89 mm Hg（范围：8.40 至 14.50 mm Hg）（≤0.001）。有和无眼睑拉钩时 IOP 的平均差异分别为右眼 2.87 ± 2.23 mm Hg（范围：0.20 至 5.20 mm Hg）和左眼 2.44 ± 1.48 mm Hg（范围：0.00 至 4.90 mm Hg）。所有眼的有和无眼睑拉钩时 IOP 的平均差异为 2.65 ± 1.89 mm Hg（范围：0.00 至 5.20 mm Hg）。放置眼睑拉钩后 IOP 的差异与出生后年龄或检查时体重之间无相关性（ = 0.11， =.41， = 0.32， =.14）。
在局部麻醉下，Barraquer 金属丝眼睑拉钩会导致新生儿的 IOP 升高，双眼的出生后年龄和性别之间无显著差异。插入眼睑拉钩后，IOP 平均升高 2.65 mm Hg。在解释新生儿的 IOP 测量值时，应考虑到这一影响。
