To evaluate the effect of pupil dilation obtained with cyclopentolate on biometric measurements using swept-source optical coherence tomography biometry.
This study involved 63 eyes of 63 healthy volunteers. After ophthalmic examination, biometry measurements of the participants were obtained with IOL Master 700 (Carl Zeiss Meditec AG, Jena, Germany). After pre-dilation measurements were taken, subjects were given one drop of cyclopentolate hydrochloride ophthalmic solution three times at 10-minute intervals. When cycloplegia had been achieved, a dilated fundus examination was conducted and post-dilation measurements were taken with IOL Master 700. The biometric parameters were recorded and SPSS Software 22.0 was used for statistical analysis.
There was a significant increase in anterior chamber depth, anterior aqueous depth and central corneal thickness values after pupil dilation (p < 0.05). A significant decrease was observed in lens thickness values after cycloplegia (p < 0.05). There were no statistically significant differences between pre-dilation and post-dilation axial length, keratometry (K1, K2) and white-to-white values (p > 0.05).
This study demonstrated there is no significant difference in axial length and keratometry measurements using swept-source optical coherence tomography biometry before and after cycloplegia.
评估使用环喷托酯散瞳对扫频源光学相干断层扫描生物测量法进行生物测量的影响。
本研究纳入了63名健康志愿者的63只眼睛。眼科检查后，使用IOL Master 700（德国耶拿卡尔蔡司医疗技术公司）对参与者进行生物测量。在进行散瞳前测量后，受试者每隔10分钟滴一滴盐酸环喷托酯眼药水，共滴三次。当达到睫状肌麻痹状态时，进行散瞳眼底检查，并使用IOL Master 700进行散瞳后测量。记录生物测量参数，并使用SPSS软件22.0进行统计分析。
散瞳后前房深度、眼前房深度和中央角膜厚度值显著增加（p < 0.05）。睫状肌麻痹后晶状体厚度值显著降低（p < 0.05）。散瞳前后的眼轴长度、角膜曲率计测量值（K1、K2）和白对白值之间无统计学显著差异（p > 0.05）。
本研究表明，睫状肌麻痹前后使用扫频源光学相干断层扫描生物测量法测量眼轴长度和角膜曲率计测量值无显著差异。
