Sanjaa-Uyen-Tumur ophthalmometer: An introduction of the objective ophthalmometer

PURPOSE: The purpose is to present the objective of the Sanjaa-Uyen-Tumur (SUT) ophthalmometer and compare its measurements with the standard Hertel exophthalmometer. METHODS: Eyeball position of 88 healthy eyes of the patients was measured using both the SUT ophthalmometer and Hertel exophthalmometer. Both methods were performed in one session by the same experienced ophthalmologist. Data were analyzed using Bland–Altman method. RESULTS: Mean age of the participants was 41.11 ± 14.08, further, 59% (26) were male and 41% (18) were female, respectively. The mean difference was 0.1420455 and the standard deviation of the difference was 0.9221067, 95% confidence interval, respectively. Based on the Bland–Altman analysis, lower limit of agreement in our study was from −2.284538 to −1.614211 and upper limit of agreement was from 1.33012 to 2.000447. According to the results of our studies, there is no relationship between the difference and the level of measurement in either plot. CONCLUSION: This SUT ophthalmometer can be used same as the Hertel exophthalmometer in ophthalmology practice as can be accurate, affordable, and objective.
