Abstract: Accommodative and vergence dysfunctions are reported to be highly prevalent among newlineschool children with estimates of close to 30% according to recent populationand#8208;based newlinestudies (Jang and Park, 2015). As these dysfunctions are latent, they are termed as nonstrabismic binocular vision anomalies (NSBVA). Due to the hidden (latent) nature of NSBVA, detection without clinical tests, just based on observation as in manifest squint, is not possible. To the best of our knowledge, there exists no data in the Indian literature on the prevalence of binocular vision (BV) anomalies so as to understand the visual morbidity due to these disorders. Among the various types of NSBVA, with constant change in the near visual demands, and worldwide increase in prevalence of NSBVA (Jang and Park., 2015; Wajuhian, 2015), it becomes important to understand the current status of visual morbidity due to NSBVA among school children in the indigenous population. Hence the BAND (Binocular vision anomalies and normative data) study group aimed to study the prevalence of BV anomalies among school children in rural and urban Tamilnadu. To classify children as normal or abnormal as indicated by various authors (Scheiman et al, newline2014), it becomes necessary to know the normal mean values for a battery of different tests conducted as part of BV assessment. Extensive literature is available for the normative data parameters for vergence and accommodation parameters in Caucasian population. If the difference in ethnicity and race are taken into account, clinical practice based on the Caucasian data compiled from various authors for different age groups might complicate the interpretation and management. Racial differences in BV parameters have been reported in the literature (Chen and Iqbal, 2000), and this demands the need for a separate Indian data. newlineMoreover, the normative data could have significant implications for the clinical practice and management of BV anomalies. newline
