Abstract Details

Purpose:

To evaluate the effectiveness of Kaleidos (auto-refractor) photoscreening in detecting amblyopia risk factors meeting 2013 the American Association of Pediatric Ophthalmology and Strabismus (AAPOS) criteria in Chinese 4 -14years

Setting:

Shenyang He Eye Hospital, Liaoning, China.

Methods:

Bilateral eyes of 502 children (1004 eyes), aged between 4 to 14 years (9.49 ± 2.7 years) underwent complete ophthalmologic examination, Kaleidos photoscreening, and KR8800 auto-refraction. The agreement of the results obtained with the photoscreening and KR800 was evaluated by linear regression and Bland-Altman plots. The sensitivity and specificity of detecting amblyopia risk factors were calculated based on the AAPOS 2013 guidelines. The overall effectiveness of detecting amblyopia risk factors was analyzed with Receiver Operating Characteristic (ROC) curves.

Results:

The mean refractive errors measured with the Kaleidos were: spherical equivalent (SE) = -1.45 ± 1.76 D, J0 = -0.02 ± 0.53 D, J45 =-0.02± 0.61D. The mean results from KR8800 were: SE = -1.05 ± 2.20 D, J0 = -0.1 ± 1.37 D, J45 = 0.05± 1.09 D. There was a strong linear agreement between results obtained from those two methods (R2 = 0.782, P<0.01). Bland– Altman plot indicated a moderate agreement of cylinder values between the two methods. Based on the criteria specified by the AAPOS 2013 guidelines, the sensitivity and specificity 80.1% and 75%.

Conclusions:

The refractive values measured from Kaleidos photoscreener showed a moderate agreement with the results from KR8800 auto-refraction. The performance in detecting individual amblyopia risk factors was satisfactory.
