Abstract Details

Purpose:

To compare photorefration using Plusoptix vision screening to that of standard cycloplegic refraction, to detect variability between different observers and to detect existence of over or under estimation of the measured refractive errors.

Setting:

Aswan university , faculty of medicine , Egypt

Methods:

203 eyes of 203 children were included. Refraction was done for each child using PlusOptix photorefraction screener by two separate observers. Under effect of cyclopentolate eye drops, retinoscopic cyclorefraction was done for those under 4 years old and autorefraction cyclorefraction using autorefractometer was done for those 4 years or older.

Results:

In the present study 203 eyes were included. There was no significant difference between the two observers as regards to mean spherical equivalent (+0.52 ± 1.54 with range of -3.8 to +5.38 for the observer 1 and 0.540 ± 1.62 with range of -3.8 to +4.8 for observer 2). In all age groups, there was no significant difference between photorefraction results and the final subjective refraction as regards to mean spherical equivalent (0.540 ± 1.62 and 0.549 ± 1.62 respectively). Although, significant difference in axis of astigmatism between both (P value <0.001) were found.

Conclusions:

Compared to standard cycloplegic refraction, photorefraction using Plusoptix screener was found to be valuable and reproducible method in spite of mild underestimation of higher refractive errors in children.
