Influences of topical cyclopentolate on anterior chamber parameters with a dual-Scheimpflug analyzer in healthy children.
OBJECTIVE
To evaluate the changes of anterior segment parameters following the topical instillation of cyclopentolate hydrochloride 1% with the Galilei dual-Scheimpflug analyzer (GSA) (Ziemer Ophthalmology Co., Port, Switzerland) in healthy children.


METHODS
Fifty children (29 boys, 21 girls) were evaluated before and 60 minutes after instillation of three drops of 1% cyclopentolate hydrochloride using the GSA. The measurements before and after cycloplegia, including anterior chamber depth (ACD), anterior chamber angle (ACA), anterior chamber volume (ACV), central corneal thickness (CCT), and pupil size, were evaluated using the paired t test.


RESULTS
The mean age of the patients was 10.27 ± 3.32 years (range: 5 to 15 years). Measurements between the two sessions were significantly different for all parameters (P < .05), except for CCT (P > .05).


CONCLUSIONS
The GSA demonstrated a statistically significant increase in ACD, ACV, ACA, and pupil size following the topical application of cyclopentolate hydrochloride 1%. These results should be considered during biometric measurement and refractive surgery planning.
