A Comparison of Cycloplegic, Non Cycloplegic & Retinoscopy Refraction on Automated Refractometer in Children aging 5-12 Years.
Ophthalmol Update Jan ;16(2):600-2.

Aims :To get to know about the comparison of cycloplegic refraction , non cycloplegic refraction and retinoscopy refraction on automated refractometer in children. Methods: A cross sectional study was done in Fatima Memorial Hospital, Lahore in which 185 children aged 5 to 12 years were included. All children had their refractive status measured with the RMA-3000 autor-efractometer (noncycloplegic autorefraction [AR]. Subsequently all children underwent cycloplegia and the refractive status was estimated again with the autorefractometer (cycloplegic autorefraction [ARC]) and traditional retinoscopy (RC) by examiners who were unaware of the results from the other techniques. Results : From 80 left eyes with negative sphere the spherical power was 0.75 D in AR than in ARC (P = 0.001) and RC (P = 0.001). From the 105 normal and hyperopic right eyes we observed that the sphere power was significantly lower (more than 0.75 diopters) in AR than in ARC (P= 0.0001) and RC (P= 0.0001) Conclusion: The use of the autorefractometer in children without cycloplegia may underestimate the actual hyperopia and overestimate the actual myopia. hence manual refraction is far better that automated refractometer.
