PURPOSE: To identify factors for different values of intraocular pressure (IOP) using the noncontact tonometer (NCT) and Goldmann applanation tonometer (GAT). METHODS: A total of 228 eyes in 114 outpatients were measured for IOP by NCT and GAT, corneal thickness, and width of palpebral fissure. RESULTS: IOP measured by NCT and GAT showed a significant correlation (p < 0.000). The difference in IOP by NCT and GAT was significantly correlated with the corneal thickness (right eye: p = 0.026, left eye: p = 0.020). The difference by NCT and GAT readings showed no correlation with the width of palpebral fissure. CONCLUSION: IOP reading by NCT is influenced by corneal thickness. LA: Japanese
