Highlighting the Profile of Stereoscopic Acuity of School Children Aged 3 to 5 Years in Cameroon | Chapter 13 | Current Practice in Medical Science Vol. 8

The current study establishes a profile of the stereoscopic acuity of schoolchildren in the Yaounde 2 subdistrict who are between the ages of 3 and 5. Binocular vision is the fundamental increase of the visual function. Stereoscopic vision, fusion vision, and spontaneous vision are its three levels. Stereopsis is the term used to describe the ability of binocular vision to recognise depths and landscapes.

In the current study, a probabilistic sampling at four levels in nursery schools was used in a cross-sectional and descriptive investigation. The Pigassou chart was used to measure far vision, while the TNO stereo test was used to evaluate stereoscopic vision. Study participants included 365 kids, of which 362 (99.2%) had stereoscopic acuity. 10.4 percent of the latter group exhibited abnormal stereoscopic vision. With ageing, the stereoscopic acuity median values improved. At 3 years, they were 120 inches; at 4 and 5 years, they were 60 inches. With age, the percentage of kids with stereoacuities of 60 or higher rose: 32.3 percent at 3 years, 66.1 percent at 4 years, and 79.6 percent at 5 years.

The profile of stereoscopic acuity in Cameroonian children lacks precision when compared to the literature. The stereoacuity keeps getting better between the ages of 3 and 5 until it reaches adult threshold levels. This test is suggested for identifying vision issues in children.
