摘      要：Background: To compare two methods of measuring intraocular pressure (IOP) and to evaluate whether repeated measurements taken with the Ocuton S applanation s elf-tonometer can improve reliability. Methods: Ocuton S and Goldmann applanati on tonometry (GAT), and corneal thickness measurements taken with the Orbscan to pography system, were successfully performed in 64 of 68 glaucoma patients. Resu lts: The median IOPs were 15.5mmHg using GAT, and 16 mmHg using the first self- taken Ocuton S measurement (n=64). The differences between the median of the GAT measurements and the first Ocuton S measurement, and the medians of the three a nd six separate Ocuton S measurements were within 3 mmHg in 52%, 59%and 67%of cases, respectively. The mean corneal thickness of all evaluated eyes was 545.3 μm. There was no effect of corneal thickness on the accuracy of either of the two devices (P 0.05). Conclusion: Repeated measurements can improve the reliab ility of the Ocuton S. However, ever with repeated measurements only every secon d patient succeeds in obtaining reliable measurements.
