Popis: Purpose Ocular components are traditionally measured using A-scan ultrasound. With ultrasound, the probe makes contact with the cornea, so there is some problem in children. The IOLMaster is non-contact device that can measure ocular components, so it can be used in children with poor cooperation. We evaluated change of ocular components after cycloplegia in children using the IOLMaster. Methods One hundred and sixty eight children aged from 3 to 15 years were recruited from the Kangbuk Samsung Hospital, Sungkyunkwan University, School of Medicine. Children with ocular problem except refractive error were excluded. Pre- and post-cycloplegic corneal curvature (CC), anterior chamber depth (ACD) and axial length (AL) on the right eye were measured with the IOLMaster. We evaluated the change of ocular components after cycloplegia by age and refractive error. Results ACD was 0.134 ± 0.134mm deeper after cycloplegia (p=.000). The amount of change had statistically significant negative correlation with age (Pearson correlation -0.332, p=.006), but it was not significantly different between myopic and hyperopic group after age correction (p=.398). AL was also significantly elongated after cycloplegia (p=.000), but the amount of change was very small (0.011 ± 0.022mm). There was no change in CC after cycloplegia (p=.428). Conclusion Effect of cycloplegia on ACD in children measured with the IOLMaster was significant. We suppose that the negative correlation between the change of ACD and age may be associated with decreasing accommodation with age.
