To assess the effect of a pediatric eyelid speculum on the measurement of intraocular pressure (IOP) in children.
Observational case series.
Intraocular pressure measurements were performed during examination under anesthesia immediately after induction. The measurements were made with and without a pediatric eyelid speculum in place.
Intraocular pressure measurements were made in 77 eyes of 45 consecutive children. The mean IOP without the speculum was 16.33 mm Hg in the right eye and 16.55 mm Hg in the left eye. With the lid speculum in place the mean IOP was 20.26 mm Hg in the right eye and 20.05 mm Hg in the left eye (P <.05).
The presence of an eyelid speculum raised IOP an average of 4 mm Hg. This effect should be considered when interpreting IOP measurements in children.
评估儿童眼睑撑开器对儿童眼压测量的影响。
观察性病例系列。
在诱导麻醉后立即进行麻醉下检查时测量眼压。分别在使用和不使用儿童眼睑撑开器的情况下进行测量。
对45例连续儿童的77只眼进行了眼压测量。不使用撑开器时，右眼平均眼压为16.33毫米汞柱，左眼为16.55毫米汞柱。使用眼睑撑开器时，右眼平均眼压为20.26毫米汞柱，左眼为20.05毫米汞柱（P<.05）。
眼睑撑开器的存在使眼压平均升高4毫米汞柱。在解读儿童眼压测量结果时应考虑到这种影响。
