目的:寻找穿透性小梁切除术后患者眼压测量的简单方法。方法:随机选取行穿透性小梁切除术后3d的患者120例120眼。分别用Goldmann眼压计和Tono-pen眼压计测量眼压,比较两种眼压测量值的差异。结果:120眼中,Goldmann眼压计所测量眼压的平均数值14.69±4.60mmHg。Tono-pen所测眼压的平均数值14.72±4.62mmHg。经统计学检验,P>0.05,Tono-pen眼压计与Goldman眼压计的测量结果无显著性差异。对于穿透性小梁切除术后的眼压测量,Tonopen眼压计与Goldman眼压计的测量结果有高度相关性。Tono-pen眼压计可以准确地估计眼压值。结论:对于穿透性小梁切除术后的的患者眼压在7～32mmHg间时Tono-pen眼压计可以作为一种准确测量眼压的简单方法。
OBJECTIVE: To find a simple method for measuring intraocular pressure in patients after penetrating trabeculectomy. Methods: One hundred and twenty eyes of 120 patients were randomly selected for the first 3 days after penetrating trabeculectomy. The intraocular pressure was measured with a Goldmann tonometer and a Tono-pen tonometer, respectively, and the differences between the two measurements were compared. RESULTS: In the 120 eyes, the mean IOP measured by the Goldmann tonometer was 14.69 ± 4.60 mmHg. Tono-pen measured intraocular pressure average 14.72 ± 4.62mmHg. Statistically, P> 0.05, Tono-pen tonometer and Goldman tonometer did not show any significant difference. For IOP measurements after penetrating trabeculectomy, the Tonopen tonometer is highly correlated with the Goldman tonometer measurements. Tono-pen tonometer can accurately estimate the intraocular pressure value. CONCLUSIONS: The Tono-pen tonometer can be used as a simple way to accurately measure intraocular pressure in patients with penetrating trabeculectomy who have an intraocular pressure between 7 and 32 mmHg.
