Abstract

Myopia is usually defined as equivalent sphere ≥-0.50D in most reported studies. However, the literature is scanty on the sensitivity and specificity of the defined myopia when researchers report the prevalence or distribution of myopia in the population under study. The objective of this study was to differentiate the sensitivity and specificity of each myopia definition of-0.50 D,-0.75 D and-1.00 D and to establish each myopia definition's capability to predict visual acuity less than log MAR 0.3 (6/12) in Malay schoolchildren. Eight hundred sixty six schoolchildren aged 7-10 years were involved in this study. Visual acuity was measured using log MAR chart and refractive error was determined using retinoscopy without cycloplegia. Our results showed that the sensitivity and specificity for myopia defined as ≥-0.50 D were 54.5% and 97.8%, respectively, for myopia defined as ≥-0.75 D were 71.1% and 97.5%, respectively, and for myopia defined as ≥-1.00 D were 83.3% and 97.2%, respectively. Areas under ROC curve for each myopia definition of-0.50 D,-0.75 D and-1.00 D were 0.676, 0.839 and 0.957, respectively. In conclusion, our results showed the optimal myopia definition for Malay schoolchildren aged 7-10 years was ≥-1.00 D using retinoscopy without cycloplegia. This myopia definition was able to establish 95.7% schoolchildren with visual acuity less than log MAR 0.3 and it has good combination of sensitivity (83.9%) and specificity (95.7%).
