The mean age of the pre-school children was 5.3 +/- 0.7 years old.<br />Results: The Lea Symbols chart showed a higher sensitivity (97.5%) compared to the Sheridan Gardiner chart (57.1%). While the Sheridan Gardiner chart showed higher specificity (92.0%) compared to the Lea Symbols chart (45.0%).<br />Conclusion: The Lea Symbols chart offers a better pick-up rate of visual impairment during a vision-screening program especially cases of amblyopia among pre-school children compared to the Sheridan Gardiner chart in Malaysia.
