目的 评价Tono -Pen眼压计的临床应用价值。方法 93例青光眼患者的 93眼纳入本研究 ,分别进行了Goldmann眼压计和Tono -Pen眼压计的测量。对两种眼压计的测量结果进行比较并评价Tono -Pen眼压计的特异度与灵敏度。结果 两种眼压计测量值相差范围 -12～ 8mmHg ,差值的绝对值≤ 2mmHg占 61 3 % ,≤ 3mmHg为 75 3 % ,≥ 7mmHg者 5 4% ,总体相关系数 0 944(P <0 0 0 1) ,眼压≤ 2 1mmHg ,Tono -Pen眼压计偏高估计眼压 0 70± 2 3 1mmHg (P <0 0 5 ) ,2 2～3 0mmHg ,Tono -Pen眼压计偏低估计眼压 1 71± 3 15mmHg (P <0 0 5 ) ,>3 0mmHg ,两种测量手段所得结果无差异 (P >0 0 5 )。Tono -Pen眼压计的特异度与灵敏度分别为 93 6%和 84 8%。结论Tono -Pen眼压计可用于青光眼的筛查 ,但不适合用于其诊断和随访。
Objective To evaluate the clinical value of Tono -Pen tonometer. Methods Ninety-three eyes of 93 patients with glaucoma were enrolled in this study and measurements of the Goldmann tonometer and Tono-Penn tonometer were performed. The tonometer measurements were compared and the Tono -Pen tonometer was evaluated for specificity and sensitivity. Results The difference between the two tonometers was -12 ~ 8mmHg, the absolute value of the difference ≤2mmHg accounted for 61.3%, ≤3mmHg was 75.3%, ≥7mmHg was 54%, the overall correlation coefficient was 0 944 (P <0 0 0 1), IOP ≤ 2 1mmHg, Tono -Pen Tonometer high estimated intraocular pressure 0 70 ± 2 3 1mmHg (P <0 05), 2 2 ~ 3 0mmHg Tono -Pen tonometer low The intraocular pressure was estimated to be 1 71 ± 3 15 mmHg (P <0 05) and> 3 0 mmHg, with no difference between the two measurements (P 0 05). Tono -Pen tonometer specificity and sensitivity were 93 6% and 84 8%. Conclusion Tono -Pen tonometer can be used for screening glaucoma, but not suitable for its diagnosis and follow-up.
