Brazilian guideline for pediatric cycloplegia and mydriasis

Reduced vision throughout early childhood is typically due to errors of refraction. Objective: To compare refractive status in children (age 5 to 15 years) checked with subjective refraction under cycloplegia versus post mydiatric test (PMT). Methods: Comparative cross-sectional study was conducted in pediatric ophthalmic clinic of College of ophthalmology and Allied vision sciences /Mayo hospital Lahore including 120 non-pathological eyes of 60 subjects. Individuals with nystagmus and deviation of eyes were excluded. Power of SE (P1) was taken as proposed number of glasses to be dispensed. After three days PMT was done and prescription of glasses with BCVA (P2) was noted and prescribed. At PMT (P2-P1) was noted and evaluated. All data entered and analyzed by using SPSS-23. P-value equal or less than 0.05 was taken as significant. Results: Among 120 eyes (n=120), the distribution of myopia was 57.5% and hyperopia was 42%. The mean age of 60 individuals (female: 35% and male: 65%) was 9.47 ± 2.50 years. Among 120 eyes (n=120), the distribution of myopia was 57.5% (n = 69 eyes) and hyperopia was 42% (n = 51 eyes). Interclass correlation: Two-way mixed effects model where people effects are random and measures effects are fixed. a. The estimator is the same, whether the interaction effect is present or not. b. Type C intraclass correlation coefficients using a consistency definition. The between-measure variance is excluded from the denominator variance. c. This estimate is computed assuming the interaction effect is absent, because it is not estimable otherwise.

Background This study compared the refraction measurements of the QuickSee wavefront autorefractor with those from clinical refraction measurements in preschool and elementary school children from public schools in Amazonas, Brazil. Methodology Refractometry was performed on 368 eyes from 368 healthy Brazilian public school students aged 4 to 7 years using both the QuickSee and subjective clinical methods under cycloplegia. Only right-eye data were analyzed. The results were converted into spherical equivalents and vector magnitudes for comparison. Results The difference in spherical equivalents between QuickSee and subjective clinical refractometry under cycloplegia was +0.38 ± 0.60 Diopters (D) (p < 0.0001). Along the 90° axis, the vector difference was +0.20 ± 0.33 D (p < 0.0001), and the oblique vector difference was +0.03 ± 0.22 D (p = 0.0395). Conclusions While a statistically significant difference was found between the QuickSee and subjective clinical refractometry results, the difference was not clinically meaningful. The strong agreement between these methods supports the utility of QuickSee as an effective tool for refractive assessment in children with limited access to eye care. These findings provide confidence in using QuickSee in public school settings as a reliable alternative for vision screening.
