PURPOSE: To investigate the effects of cyclopentolate hydrochloride 1% on the main numerical parameters of anterior segment with Pentacam rotating Scheimpflug camera in children.
SETTING: Ege University Faculty of Medicine, Department of Ophthalmology.
METHODS: Pentacam measurements of 50 (23 boys and 27 girls) children before and after 45 min of cyclopentolate hydrochloride 1% instillation were performed and compared with 31 (17 boys and 14 girls) no medication instilled control group. Measurements of the control group (cycloplegia-free) were taken at two separate sessions with 45-min intervals. For comparison of the test parameters, paired t-test in the groups and unpaired t-test in between the groups were used.
RESULTS: Mean ages in the study and control groups were 10.06 ± 2.87 (range 6 and 16 years) and 9.87 ± 2.72 (range 6 and 16 years), respectively, and the difference was statistically insignificant (p > 0.05). In the study group, measurements between two sessions were significantly different for the parameters of anterior chamber depth (ACD), anterior chamber volume (ACV) and central corneal thickness (CCT) (p < 0.05), whereas none of the parameters was different between two sessions for control group.
CONCLUSIONS: Cyclopentolate hydrochloride 1% instillation leads to significant decrement in CCT. ACD and ACV are the other important refractive parameters that increase significantly after cycloplegia. Effects of cycloplegia on these parameters for Pentacam measurements should be regarded for proper clinical interpretation in children.
