Aim. To establish the profile of the stereoscopic acuity of school children aged 3 to 5 years in the Yaounde 2 sub-division. Methodology. We conducted a cross-sectional and descriptive study on a probabilistic sampling at 4 levels in nursery schools. Far vision was measured using the Pigassou chart, and the stereoscopic vision was assessed by means of TNO stereotest. Results. We examined 365 children among whom 362 (99.2%) had a stereoscopic acuity. Out of the latter, 10.4% had an abnormal stereoscopic vision. The median values of the stereoscopic acuity were refined with the age. They varied from 120'' at 3 years, to 60'' at 4 and 5 years. The proportion of children having a stereoacuity ≤ 60'' increased with the age; 32.3% at 3 years, 66.1% at 4 years, and 79.6% at 5 years. Conclusion. The profile of the stereoscopic acuity in Cameroonian children does not have any specificity compared to the literature. The stereoacuity continues to be refined between age 3 and 5 to reach the threshold values of the adult. This examination is recommended for the screening of visual disorders in childhood.
