Popis: Purpose: Cycloplegic refraction is mandatory for children to know the eye's refractive status. In this study, we compared cycloplegia induced by cyclopentolate 1% to that induced by atropine 1% by means of retinoscopy. Methods: In this parallel-designed interventional study, we included 67 children aged between 4 and 17 years. After the initial retinoscopy under cyclopentolate 1% (used twice in each eye), we repeated it a week later under atropine ointment 1% (used twice a day for 3 days); both were done by the same trained optometrist masked to the drug. Each eye's refraction was converted to spherical equivalents (SEs), and the values averaged between the two eyes of each child under each drug. We compared SE with paired t-test (JASP 16.4). In addition, we performed correlational analysis, and looked for agreement using the Bland–Altman plot. Significance was set at P < 0.05. Wherever possible, 95% confidence intervals (CIs) are quoted. Results: The mean SE with atropine was +1.93 ± 2.0 D, compared to +1.75 ± 1.95 D under cyclopentolate. On average, atropine induced greater cycloplegia by a mere 0.18 D (95% CI: 0.07 to 0.29 D, P value 0.002). The two cycloplegic refractions correlated significantly (Pearson's r: 0.975, P < 0.001). The Bland–Altman plot revealed the limits of agreement as 1.06 and −0.71 D. Conclusion: Our study suggests that cyclopentolate works for the most part as well as atropine to attain cycloplegia. Atropine may be considered for children less than 15 years of age with greater than 5.0 D of hyperopia. Cycloplentolate, with its advantages of quick action and short duration, should form the first go-to topical cycloplegic in busy outpatient clinics.
