摘要

Oculab Tono-Pen tonometry and non-con tact computerized tonometry were compared with Perkins applanation tonometry in 206 eyes of 106 patients without corneal disorders. We found 82% of the Tono-Pen readings to be within ±2 mmHg of the Perkins applanation tonometry (r=0.96). There is no significant difference between Tono-Pen and Perkins readings in the 11-35 mmHg interval (p＜0.05). However, Tono-Pen reading tends to overestimate in the 2-10 mmHg interval and underestimate in the 36-50 mmHg interval. In non-contact computerized tonometry, 68% of the readings to be within ±3 mmHg of the Perkins applanation tonometry (r=0.92). No significant difference under 36 mmHg was noticed between non-contact tonometry and Perkins readings, but it tends to underestimate above 36 mmHg. It is quite accurate, safe and convinent in using Tono-Pen for screening and clinical evaluation of glaucoma patients.
