Abstract

This paper highlights our experience of ophthalmic screening with vision screener (plus optix) for a sample size of 256 mentally challenged subjects. A team of optometrists and ophthalmologist visited 6 special schools to assess ocular problems among mentally challenged population where initial eye screening by vision screener followed comprehensive ophthalmic examination. Among 256 students 169 had ocular problem and 87 subjects had no ocular problem. Ophthalmologist screened 111subjects to have ocular problem. Vision screener showed accuracy of 65%. PlusoptiX had a sensitivity of 91.1% , specificity 52.4% , positive predictive value 59.2% , and negative predictive value was 87.4% .Ocular morbidities detected were squint 21%, myopia 38%, astigmatism 19 %Hypermetropia 1%,absorbed cataract% ,chorioretinal Colobama, 1% Pseudophakia 5% .Vision screener is a promising portable tool to detect ocular problem among subjects with cognitive delay that simplifies the ocular examination.
