PURPOSE: To evaluate the effect of an eyelid speculum on intraocular pressure (IOP) measurements in newborns. METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.
