Abstrakt: Purpose: To evaluate whether manual upper eyelid elevation (MUEE) affects intraocular pressure (IOP) values obtained with a noncontact tonometer (NT).
Methods: This cross-sectional study included 122 eyes of 122 non-glaucomatous adults. All patients underwent IOP measurement using both NT and Goldmann applanation tonometer (GAT). The order of measurements was NT without MUEE, NT with MUEE, and GAT. Both eyes of each patient were measured and one of the eyes was randomly selected for inclusion in the study. Central corneal thickness (CCT) and palpebral fissure height (PFH; distance between upper and lower eyelids) was recorded.
Results: The patients' mean age was 43.91 ± 12.36 (20-61) years and 62.3% were women. Mean IOP values measured by NT without MUEE, NT with MUEE, and GAT were 15.98 ± 2.39, 15.84 ± 2.53, and 14.33 ± 2.3 mmHg, respectively. There was no statistically significant difference in mean IOP between NT without and with MUEE (p = 0.506). Mean IOP values obtained by NT with and without MUEE were significantly higher than those obtained by GAT (p < 0.001). The difference in IOP values measured by NT without and with MUEE was positively correlated with PFH (r = 0.214; p = 0.018). CCT and IOP values obtained by NT without MUEE and GAT were positively correlated (r = 0.300; p = 0.001 and r = 0.311; p = 0.001, respectively).
Conclusion: MUEE does not have a significant effect on IOP measurements by NT. The difference between IOP measured by NT without and with MUEE increases with greater PFH.
