The photorefraction results were calibrated to those of cycloplegic retinoscopy. A good agreement was found between the 2 sets of values. The frequency distribution of refraction errors were similar to those presented by Ingram (1979). The aim to detect hyperopia ≥+2 or myopia ≥‐4 diopters together with significant anisometropia or astigmatism was fullfilled with high reliability. Low degrees of hyperopia, myopia and astigmatism might be missed. Photorefraction therefore is considered to be a reliable, simple and cheap tool with high sensitivity and specificity in screening small children for significant refraction errors.Read More
