[Comparison of refraction with or without cycloplegia using Retinomax®or Plusoptix®devices].
OBJECTIVE
To evaluate the refraction in children measured with Plusoptix®without cycloplegia vs. Retinomax®apparatus with cycloplegia.


METHODS
Measure of refraction with Plusoptix®in children>1year old referred for systematic vision screening, then measurement after cycloplegia with cyclopentolate by the Retinomax®device.


RESULTS
Thirty-three children were included, i.e. 66eyes. Mean age was 40.7months (minimum 12; maximum 114). The Spearman correlation coefficient for the spherical equivalent was 0.52 (Plusoptix®vs. Retinomax®comparison; P<0.0001=moderate correlation). The Spearman correlation coefficient was 0.73 for astigmatism (Plusoptix®vs. Retinomax®comparison; P<0.0001=strong correlation). The Plusoptix®sensitivity for measurement of refraction was 57%, 43% and 43% respectively for spherical equivalent, sphere and astigmatism.


CONCLUSIONS
The correlation of astigmatism values is strong, whereas the correlation of sphere values is moderate. Plusoptix®seems to be unable to measure the exact refraction, because there is too large a dispersion of refraction measurements with Plusoptix®, compared to the exact refraction measured with the Retinomax®. Moreover, the sensitivity of Plusoptix®is low. Cycloplegic refraction remains indispensable in children.
