Purpose: To compare refractive measurements of noncycloplegic photoscreener Plusoptix S12R with cycloplegic retinoscopy, noncycloplegic autorefractor, and cycloplegic autorefractor in children.
Methods: The study population (200 eyes of 100 children) was divided into two groups: Group 1 (age 3-7 years) and Group 2 (age 8-15 years). In Group 1, Plusoptix was compared with cycloplegic retinoscopy. In Group 2, Plusoptix was compared with cycloplegic retinoscopy and autorefraction. The second group was made because the younger group was found to be uncooperative for autorefraction. Paired t-test and Pearson's correlation were used for statistical analysis.
Results: The mean difference in sphere (DS), spherical equivalent (DSE), and cylinder (DC) between cycloplegic retinoscopy and Plusoptix in Group 1 was 0.68 ± 0.55 (P < 0.001), 0.77 ± 0.61 (P < 0.001), and 0.18 ± 0.28 (P < 0.001), respectively. In Group 2, DS, DSE, and DC between cycloplegic retinoscopy and Plusoptix were 0.86 ± 0.49 (P < 0.001), 0.97 ± 0.51 (P < 0.001), and 0.23 ± 0.28 (P < 0.001); between cycloplegic autorefractor and Plusoptix were 0.69 ± 0.47 (P < 0.001), 0.74 ± 0.49 (P < 0.001), and 0.10 ± 0.31 (P = 0.002); and between noncycloplegic autorefractor and Plusoptix were - 0.25 ± 0.39 (P < 0.001), -0.19 ± 0.41 (P < 0.001), and 0.11 ± 0.31 (P < 0.001), respectively. Pearson's correlation coefficients of S, SE, and C between Plusoptix and cycloplegic retinoscopy were 0.948, 0.938, and 0.924 in Group 1 and 0.972, 0.972, and 0.946 in Group 2, and these values were statistically significant. Bland-Altman plots showed good agreement between cycloplegic retinoscopy and Plusoptix in both groups. Plusoptix gave axis values within 10° of cycloplegic retinoscopy in 81.56% of eyes in Group 1 and in 71.44% of eyes in Group 2.
Conclusion: Plusoptix photoscreener can be used for prescription of axis of cylinder in children; however, other refractive measurements must be refined by cycloplegic retinoscopy.
