The Effect of Topical 1 Cyclopentolate on lOLMaster Biometry

摘要

Purpose. To investigate the effects of topical cyclopentolate on ocular biometry parameters in healthy young adults. Methods. Ocular biometry measurements were performed twice with 45-minute intervals by use of the lOLMaster. Effects of topical application of 1% cyclopentolate were examined in 25 eyes from 25 young adults (group 1) before and after its application. As a control (cyclopentolate-free, group 2), 30 eyes from 30 age- and sex-matched healthy subjects were evaluated within the same period.Results. There was no difference between the groups with respect to mean (±SD) ages (group 1: 23 [+3.19] years [range, 18 to 28 years] vs. group 2: 22.6 [+2.7] years [range, 18 to 28 years], p = 0.61 6). In group 1, the anterior chamber depth and horizontal iris width (white-to-white distance) measurements between the two sessions were significantly different, whereas the axial length was not. In group 2, none of these parameters were different between the two sessions. Conclusions. Topical application of 1% cyclopentolate caused an increase in the anterior chamber depth and white-to-white distance values without any significant effect on axial length measurement. It is necessary to consider these effects on measurements taken with an lOLMaster in young adults in whom 1% cyclopentolate has been applied.
