| Abstract |
|
IOP was measured with 3 different tools, namely, the Pulsair peumotonometer(A), the Oculab Tono-pen(B), and the Goldmann applanation tonometer(C), in order to evaluate the clinical usefulness of each. 174 eyes without corneal opacity and corneal edema were measured. The results were as follows; 1. The correlation coefficient was 0.85(P<0.005) between A and C, 0.82(P<0.005) between B and C and 0.83(P<0.005) between A and B. The correlative formulas between the measurements of IOPs were produced to be: A = 0.73 X C + 5.49, B = 0.76 X C + 5.33, A = 0.78 X B + 3.87. 2. At low IOPs(<10 mmHg) as Measured by C(11 eyes), the correlation Coefficient was 0.81(P<0.05) between B and C. However, A and B valuse tended to be highter than C value. 3. At relatively high IOPs(>20 mmHg)as measured by C(56 eyes), the correleation coefficient was 0.83 between A and C(P<0.0001) and 0.82(P<0.0001) between B and C. However, A and B values tended to be lower than c value. 4. At relatively high IOPs(>20 mmHg)as measurde by C, the sensitivity of A was 60.53% and that of B was 73.68%. According to this study, no significant difference could be found among these three tools. However, at low IOPs(<10 mmHg), the Oculab Tono-pen and Pulsair pneumotonometer tended to show higher values than the Goldmann applanation tonometer. In case of relatively high IOPs(>20 mmHg as measured by the Goldman tonometer), the Oculab Tono-pen and Pulsair pneumotonometer tended to show lower values than the Goldmana applanation tono meter and the sensitivity of the Oculab Tono-pen showed higher than that of the Pulsair pneumotonomer. |
